How to avoid: By default, MicroStrategy uses database connection caching. the alias) is sum_quantity. The SQL COUNT() function is used to count the rows in a table, and can be used with ‘ALL’ and ‘DISTINCT’ arguments. This article describes how to use wildcards to display temporary table names in pre/post statements. The above example would not be valid with multiple months in the answer because the >= expects single values for its operands. Transformations allow you to apply an attribute-element based offset to compare metric data. Calculating a Compound Metric. Select one: To create a new security filter, click New. They act as containers for non-standard SQL expressions that MicroStrategy does not support. (For information on object levels, see Order of Precedence . CREATE and INSERT statements are not supported. ) From the Tools menu, select Show Advanced Settings. This article describes how to create a metric with an attribute as a filter using a Case statement in a Visual Insight dashboard in MicroStrategy Web. , row number) is non-deterministic. In MicroStrategy Developer, log into the Server Project Source as a user with administrative privileges. Action If the CASE expression has only one branch -- i. Grouping. The location of each property in the CREATE TABLE statement is given below. So when the value was changed to 'Check for NULL in all queries' at the report level, the MicroStrategy SQL Generation Engine issued a NULL validation for the metric. Browse to the filter you want to convert and click Open. The user should locate the VLDB. This flexibility is an important benefit of VLDB properties because it permits adjustment of many levels such as: REPORT - highest priority. 7. There are two options for this property: CREATE and INSERT statements are supported. Customizing a CREATE TABLE statement is only possible for a permanent table. In general, a user specifies a list of conditions and corresponding return values. Create a new plug-in and give it a meaningful name. MicroStrategy SQL Generation Engine will not automatically add parentheses around the list. Case can be used for categorizing data based on multiple conditions. The 'Where clause driving table' Very Large Database (VLDB) property indicates to the MicroStrategy Engine which table to use when a filter needs to be applied. Interact with the engaged MicroStrategy Community to get answers to all your. In MicroStrategy, a hint can be defined in VLDB properties to appear within a MicroStrategy-issued SQL statement. There is no VLDB setting associated with this option. The following three options are available for the VLDB property. Why MicroStrategy Why MicroStrategy; Customer Stories; PlatformExecute the report and see the result below. exist as a separate pass in SQL. The SQL SUM () Function. x. Multiple passes are generated only when necessary to resolve all the metric definitions. The option is available in the Project Level VLDB properties under "Query Optimizations" as seen below. Each conditional metric contains a copy of employee list (in an IF statement) Employee list filter is moved to a separate metric (Flag metric) Employee list filter is moved to a Filter object. Unless the defaults are changed, the function ranks the values in ascending order by the value of the metric, and the rank is an integer. Select Data/VLDB Properties. x attempts to combine metric calculations and attribute lookups into one pass of SQL. Example. The Use default inherited value option indicates the level that is active, while the SQL preview box. We will calculate the total value of SQL numbers using the SUM() function. This information is available for each property in the VLDB Properties dialog box at each level. Set up the Enterprise Manager. •. g. Using Apply functions is recommended only when corresponding functionality does not exist in MicroStrategy. This metric divides the sum of VOL fact at report level by [Net Weight] after applying it a character replace at BBDD level with ORACLE's replace function (it seems that the BBDD is ORACLE), and breaks it down by product. There are three options available: No interaction - static custom group; Apply report filter to custom group This article notes how to remove LTRIM functions from SQL generated against Oracle Ca se functions Microstrategy Case functions return specified data in a SQL query based on the evaluation of user-defined conditions. See full list on When calculating the grand total over yearly revenue, the Analytical Engine simply sums the three distinct values and produces the right total, without the inflation that would occur if the sum were taken over the 12 rows displayed in the report. If the select level is the same as the table key level and the table's true key property is selected, DISTINCT is not used. Syntax. This VLDB settings influence the table creation type in the SQL passed to the Teradata database when Intermediate Table Type is set to True Temporary. Pass-through expressions, also called Apply functions, allow use of special functions or syntactic constructs beyond what MicroStrategy can create on its own, but can be obtained through the relational database. Tutorial project is used here. the aggregation function is not applied to the fact for the metric calculation. They act as containers for non-standard SQL expressions that MicroStrategy does not support. x, the only options were to drop tables or do nothing. Note: This behavior does not apply to server-level partitioning, in which tables are partitioned natively within the database. ; In some limited cases you can rewrite the aggregate to avoid. Two different passes of SQL for metrics which only differ via a simple filter are note merged via SQL Global Optimization levels 3 and 4 despite notes that it can. For DataFrames, specifying axis=None will apply the aggregation across both axes. When you need to use an Apply function, MicroStrategy encourages you to submit an enhancement request for inclusion of the desired feature in a future product release. The following steps describes how to create such derived metric. They can also help you take more advantage of the data. Qualify on the attribute form that you want to compare (presumably the Year ID), and then in the Operator section, change the dropdown from its default 'Value' to 'Custom'. Join common key on both sides. x mixed case columns names for a DB2 database by default have SQL generated with quote characters enclosing the name . The following settings are advanced properties which are. The VLDB property "Attribute ID Constraint" is used during creation of intermediate tables to specify whether the attribute ID columns in those tables will or will not allow null values, or to use other constraints allowed in the warehouse's SQL implementation. To configure:-. Instead, it. If you are upgrading to MicroStrategy 10. It does not apply to situations where index creation occurs before insertion of data. To do this, the "Preserve all final pass result elements" VLDB property must be set at both attribute and report level. In general, a user specifies a list of conditions and corresponding return values. This article describes the purpose of the Sub Query Type VLDB property in MicroStrategy. The database was created with files stored directly in Azure blob storage , using a Premium Storage. The Security Role Editor opens. This article describes how to modify MicroStrategy to remove coalesce functionsOpen the VLDB Properties Editor: . The Security Filter Editor opens. What function does the MicroStrategy Intelligence Server serve? Ans: Query processing; Metadata repository management; Data caching and Intelligent Cubes; Security and authentication; Load balancing; 47. This function is used to display the ranking of values in a list relative to the other values. Mostly you should do nothing about it. Default value changed for "Separate Count Distinct" VLDB setting for Impala 2. Note that the SUM() function ignores NULL values. In the Attribute Editor, on the Tools menu, select VLDB Properties. Sum is a group-value function. The window size is a parameter which tells the function how many of the values should be included in the calculation. In general, a user specifies a list of conditions and corresponding return values. Wherever you can define an expression, you can use a function. 1) Create Metric 1 which is the sum of the fact that is to be in the columns. Since the report or template is not associated with a specific database instance, the primary. This article describes a scenario where SQL will be generated with intermediate tables regardless of the intermediate table type VLDB propertyMany of MicroStrategy’s OLAP functions are calculated via SQL in SAP HANA rather than in the MicroStrategy analytical engine. Ca se functions Microstrategy Case functions return specified data in a SQL query based on the evaluation of user-defined conditions. All of the template attributes will be considered as a unit. Visit the MicroStrategy download site to download the latest supported version of this product. a temp table is created but not referenced in a later pass. on how division by zero is handled and can cause failures when your queries use features like indexed views, computed columns or XML methods. How to change the syntax is described in detail by using examples. The apply functions act as containers for non-standard SQL expressions being passed to the database. The 1NF table will have one number per row, and will contain more rows than the initial table. In the latter case, intermediate tables would be left on the database; administrators could remove them using a database-side scheduled task. 1 client subtotal behavior. , a temporary table is created but not referenced in a later pass; Reuses redundant SQL passes KB37567: MySQL table specific SQL hints cannot be used in reports against MicroStrategy 9. In general, a user specifies a list of conditions and corresponding return values. Unless the defaults are changed, the function ranks the values in ascending order by the value of the metric, and the rank is an integer. SQL. By default, MicroStrategy generates multi-pass SQL using derived tables with Teradata 12 (and higher). For use cases, examples, sample code, and other information on every VLDB property. To modify the VLDB Properties at the report level edit datamart report and select Data > VLDB Properties…. CAUSE: The MicroStrategy SQL Generation Engine distinguishes between the SQL passes generated for the Report (to return the data for the result set) and the passes generated for the datamart (to create and populate the datamart table) when applying the VLDB settings. ) User-defined. =SUMIF (range, criteria, [sum_range]) Range = range of cells where you want to check the criteria. The database was created with files stored directly in Azure blob storage , using a Premium Storage. Select the Security Filters tab. The name of the new result column (i. Need to find the sum of the bill amount for particular orders. The VLDB Properties Editor opens. so that SQL generated for one report can be manipulated separately from the SQL generated for a different report. For example, in the following formula - MovingSum (Revenue, 3) - only the previous three values are to be included in the. Criteria= the condition. It is a new feature in. It is used to insert any single-value, database-specific functions and simple operators directly into SQL. Number of Views 822. ADDITIONAL INFORMATION:. Database Instance. You can use them in many different capacities, which include, creating or modifying both schema and user objects. Metric definition: Sum (IF (Employee@ID In (1,2,4,5),Revenue,0)){~+} This is good as a quick solution, since. the aggregation function is not applied to the fact for the metric calculation. The possible values for this VLDB property are: • Permanent table46. For example, if a ranking window function is used, the rank is computed with respect to the specified order. Set up the Enterprise Manager. What I ended up doing is run the query without the Sum () Function and then use the Totals feature that is available on forms in Datasheet view. [TOT_DOLLAR_SALES]) AS Revenue into [ZZEA00] from. The metric join type, described in the previous section, is not the only VLDB property that affects metrics. This document discusses Microsoft SQL Server Database support in MicroStrategy, provides an overview of the integration, summarizes supported workflows, and describes configuration and implementation details. This is an OLAP function. Apply (Pass-Through) Functions MicroStrategy Apply Functions provide access to functions or syntactic constructs that are not standard in MicroStrategy but are provided by various Relational. In MicroStrategy, SQL Global Optimization reduces the total number of SQL passes with the following optimizations: Eliminates unused SQL passes, e. 3. For example, if attribute Region is 'Central' then derived metric value should be 'Profit + Cost'. (For step by step instructions on creating a new plug-in, please navigate to Home > Web SDK > Customizing MicroStrategy Web > Web Customization Editor. As you see, the sum of values in the quantity column in the table product is 7. Follow the steps below to change the property. The types of arguments determine how the parameter markers inside the pattern are replaced. The MicroStrategy SQL Generation Engine can produce the following SQL in some circumstances, typically involving incorrect use of attribute roles in the schema. In MicroStrategy, there is a Very Large Data Base (VLDB) property, "Additional Final Pass Option," that configures whether or not the engine will optimize SQL into a single pass when possible. Function. Note how adding an unrelated dataset unexpectedly changes the data returned by M02=Sum(Case): Cause This is a known issue in MicroStrategy 2019. Syntax. Let us create one simple table named numbers and store the. sum #. The formula of a simple metric is based on group functions (such as sum or average). Transformations − They are the data transformation features used for time-series based analysis of the data. For example, when counting from the ‘Employees’ table, ‘TotalEmployees’ (using ‘ALL’) is 5, indicating there are 5 employee IDs in total, whereas ‘UniqueDepartments’ (using ‘DISTINCT’) is 3, indicating. 1. This is a single-value function. This is a known issue prior to MicroStrategy SQL Engine 9. Group by position. For any Apply function, the attribute form in the arguments should be a single form—not a form. You can change VLDB properties to alter the syntax of a SQL statement and take advantage of database-specific optimizations. We're sorry. ; Distinct is a TRUE/FALSE parameter that allows you to. x. Each of the functions in this category substitutes for one of the function types mentioned above and can be used wherever that type is. This allows the FOJ to be rewritten to a different kind of join in the query. There is no VLDB setting associated with this option. In general, a user specifies a list of conditions and corresponding return values. Why MicroStrategy Why MicroStrategy; Customer Stories; PlatformYou can use the SQL DISTINCT clause within the SQL SUM function. Rank) calculated in Analytical Engine" found under the 'Metrics' folder in the list of VLDB properties. In MicroStrategy Developer, log into the Server Project Source as a user with administrative privileges. Note: There is an additional "Do not do downward outer join" setting that automatically orders the metrics based on dimensionality. select distinct a11. They are treated as 0s in the calculation. The attribute uses a CASE statement to replace NULL values with -999. 6. UnderstandingFunctionsinMicroStrategy 5 TheBasicsofMicroStrategyObjects,ObjectDefinitions,andFunctions 6 FunctionSyntaxandFormulaComponents 9 Ca se functions Microstrategy Case functions return specified data in a SQL query based on the evaluation of user-defined conditions. pass as Prompt answer. This procedure assumes you are already working with a metric in the Metric Editor. The SUM() function, like other aggregate functions, is typically used with the GROUP BY clause. Case This function evaluates multiple expressions until a condition is determined to be true, then returns a corresponding value. Governor. With MicroStrategy, SQL optimization is performed, by default, across passes corresponding to different elements of a Custom group when possible. Examples of SQL SUM() Given below are the examples of SQL SUM(): Example #1 – Using a single column. Select the filter or prompt to apply to the metric using one of the following methods: To type the filter or prompt directly, begin typing the name of the filter or prompt in the field in the Condition area. Intermediate Table Type. This type of formula is called a base formula, which can contain arithmetic operators, attributes, facts, group functions, and non-group functions. The impact is limited to MicroStrategy Command Manager 9. You can change VLDB properties to alter the syntax of a SQL statement and take advantage of database-specific optimizations. The Apply functions are not meant to take the place of the standard MicroStrategy functions. After running a report containing the attribute "Subcategory" and metric "Sum of COST", "Sum of COST" is found not aggregated but just listed all the related records in the data source file. That is, we can define the order in which operations are performed, optimization level, joins intermediate steps, Hints, and many more things that even go into advanced complexity. However, the expression '' alone will not check for NULLs although the Very Large Database (VLDB) setting is activated. This setting provides two options - 'Permanent table' or 'True temporary table'. These settings can be changed in the VLDB Properties dialog box for either reports or the database instance. Loading × Sorry to interruptIn the Functions pane, hover over the If or Case function and click Edit. Choose the database instance and then open VLDB Properties. There is a method to change the default syntax for table and column names while generating MicroStrategy SQL during report execution in MicroStrategy by using VLDB properties. Note: The above caveats apply only when the "Do not do downward outer join" setting without automatic ordering is used. To use an element list prompt with Freeform SQL, the following conditions must be met: The prompt must be based on an attribute in the project's primary schema (a Freeform SQL or. CAUSE: The attribute form used for the 'group by' clause of the SQL generated is not an ID form. You can, however, use a function that does not match the function or functions used to define the metric. Analyze the low performance query using DBA knowledge, add. When a Database Instance is configured to use the “Azure SQL Data Warehouse” database connection type, the recommended values for all VLDB properties will automatically be. The following. In general, a user specifies a list of conditions and corresponding return values. IMPORTANT: If Report Pre and Post Statements are defined in report or template level VLDB Properties, these will override the settings in database instances. How to confirm if the parameterized queries feature is on or off? Edit your DB instance from Developer path Administrator -> Configuration Managers -> Database Instances , or the DB role from Web data import page Add External Data -> Oracle ->Any. In the VLDB Properties window, expand the folder called 'Tables'KB14618: How do pre/post statements in the VLDB properties affect the SQL statement when executing reports in Microstrateg… Number of Views 3. DBMS - most general. Several additional VLDB properties are introduced with MicroStrategy 9. For more information on the SUM() function, you can read this complete explanation of the SQL SUM() function. The types of arguments determine how the parameter markers inside the pattern are replaced. Viewing and Changing VLDB Properties. Hi, I am having the same problem with Microstrategy Version 8. Go to Tools menu to enable the option “Show advanced settings” if it is not. Ca se functions Microstrategy Case functions return specified data in a SQL query based on the evaluation of user-defined conditions. As shown below, for a specific report, the 'Group By ID Attribute' VLDB property is set to 'Group by column' instead of 'Group by expression' to avoid using an ApplySimple. x. Choose the database instance and then open VLDB Properties. This section focuses on the VLDB properties that are set at the metric and report level. Each conditional metric contains a copy of employee list (in an IF statement) Employee list filter is moved to a separate metric (Flag metric) Employee list filter is moved to a Filter object. Case functions return specified data in a SQL query based on the evaluation of user-defined conditions. CAUSE: MicroStrategy can support multiple (more than 5) pre-statements to put in a report. ')"; [Net Weight. This knowledge base article describes an issue in MicroStrategy 10. This is a database instance level VLDB setting. Create a formula in it of. x and 10. Watch free 3-5 minutes tutorial videos, with subtitles available in 9 languages, to build product fluency! Start learning. Always consider to collect database statistics as the query execution plan is generated based on that. [M1]:. Uncheck the 'Use default inherited value' check box, if it is checked, and set the option to 'Permanent Table,' as. e ('Call [SP]') it does not. In the condition you can use logical operator (<,>,<>,=) and wildcards (*,$) for partial conditions. Apply functions: These functions provide access to functions and syntactic constructs that are not standard in MicroStrategy but are offered by various relational database. Select VLDB Properties from the Data menu to access the VLDB Properties (Report) dialog box. Attribute. Database instance, report, and templateSYMPTOM: The user has a report where the VLDB property of SQL Global Optimization has been set as "Level 4: Level 2 + Merge All Passes with Different WHERE. Example include ApplySimple, ApplyComparison, etc. If M1 does not equal any of the values in the list, then it returns a default value. Double-click the security role you want to assign to the user or group. Controls whether two fact tables are directly joined together. If you are not, do one of the following:Here are the series of steps to setup report objects in which metrics and subtotals so only the subtotal field will contain the RunningSum and the regular metric values will be standard sum values. This means that the MicroStrategy internal OLAP function 'MovingSum' will be performed on the Sum() aggregation, sorted by the month ID with a window size of 2 (2 last values). Enable Set Operator Optimization (if supported by database and [Sub Query Type]): Use set operators when possible. This issue has been addressed starting in MicroStrategy 9. The SQL hint VLDB property places the desired custom SQL inbetween the select keyword and the columns in SQLThis article notes how to setup Ranking for metrics that do not return data for all attribute elementsThis property is found in the Select/Insert folder of the VLDB property editor: This property has four options: Group by expression. REGION_NAME) REGION_NAME,Apply functions: These functions provide access to functions and syntactic constructs that are not standard in MicroStrategy but are offered by various relational database management system (RDBMS) platforms. . The CaseV function takes a numeric value M1 as input and compares it to another numeric value V1. There are multiple ways to intervene the database to generate a better SQL execution plan. Returns the date of the first day of the month in which date or timestamp occurs. 0 or above, to pick up the fix, enable project level setting "Data Engine Version" to 11. Case This function evaluates multiple expressions until a condition is determined to be true, then returns a corresponding value. 0 and higher). ACTION: This is addressed MicroStrategy 11. Apply Functions provide the capability for MicroStrategy customers to leverage functions specific to RDBMS but not standard in MicroStrategy. MicroStrategy SQL Generation Engine will not automatically add parentheses around the list. Aggregate functions and subqueries are not. To access the VLDB properties editor at the project level in the MicroStrategy Cloud Environment, please use either a Desktop Designer or Architect user account to connect to MicroStrategy Developer. The chart below shows the order of precedence of the VLDB properties: The arrows depict the override authority of. MicroStrategy pushes the calculations for the following list of built-in OLAP functions down to SAP HANA using the associated SQL patterns. This calculation can be aggregated from the Employee level to the Region level. g. VLDB properties allow you to customize the SQL that MicroStrategy generates. This VLDB setting is located in the 'Indexing' folder and has the following options:The 'Create Individual Index' VLDB setting was introduced in MicroStrategy 8. The following list of articles can be used for further reference regarding the 'derived table' behavior with MicroStrategy SQL engine. The VLDB property's behavior will be demonstrated using the following attribute and report. Report as Filter inherits its parent report's VLDB setting instead of using its own. `Temporary view` intermediate table type VLDB settings is not applied in MicroStrategy when using Warehouse Partition Mapping Table. The functionality of Apply functions is provided by wrapping the expression, as a string, inside a dedicated (Apply) function call. Subqueries (or correlated subqueries) are used infrequently but significantly in the MicroStrategy SQL Generation Engine. 0 and above. METRIC. However, the SQL used to execute the report can still be viewed and obtained. In general, a user specifies a list of conditions and corresponding return values. REGION_ID REGION_ID, max(a13. x. In contrast with warehouse partitioning, a metadata partitioning solution does not require a Partition Mapping Table (PMT) stored in the warehouse. Case This function evaluates multiple expressions until a condition is determined to be true, then returns a corresponding value. As seen below, the total subtotal function and dynamic aggregation function for MetricTest was changed from Sum to Maximum. Launch Project Configuration, select "SQL Data warehouses" under "Database instances" tab. The resulting SQL will contain just the Metric Alias. x where report SQL statement containing semi-colon (;) in the Report Pre Statement 5 VLDB properties will cause report to fail in MicroStrategy 10. Developers can retrieve the report SQL statement when running a report with the following customization: Launch the Web Customization Editor. Users can explore, filter, and visualize data with drag-and-drop functionality. Case This function evaluates multiple expressions until a condition is determined to be true, then returns a corresponding value. The VLDB setting "Do not do downward outer join for databases that support full outer join" is appropriate in the following situations:The following steps provide an overview for configuring secure Freeform SQL text prompts: Step 1: Identify Database Support for Parameterized Queries. x. The SQL SUM () Function. Rank) calculated in Analytical Engine" found under the 'Metrics' folder in the list of VLDB properties. If the option for multiple passes is selected, all metric calculations will be performed in separate passes. x as the SQL hint VLDB property doesn't generate the desired SQL. 1. VLDB properties allow you to customize the SQL that MicroStrategy generates, and determine how data is processed by the Analytical Engine. MicroStrategy value prompts do not allow multiple values. If an attribute is the lowest level attribute in a hierarchy, then the MicroStrategy SQL Engine will place a key beside this attribute in its logical table view. IMPORTANT: If Report Pre and Post Statements are defined in report or template level VLDB Properties, these will override the settings in database instances. x and higher. This sometimes produces SQL that is expensive to run on the database, particularly if multiple attribute lookup tables are combined using cross joins. " In MicroStrategy SQL Generation Engine 8. This article explains how the preserve all final pass result elements property works at the attribute level in MicroStrategyIn MicroStrategy Developer, the report SQL View shows this time as "Total Other Processing time" in summary and as "Other Processing Time" in the first SQL Pass. This means that the MicroStrategy internal OLAP function 'MovingSum' will be performed on the Sum() aggregation, sorted by the month ID with a window size of 2 (2 last values). With VLDB properties correctly configured, a report can join to some lookup tables using outer join and others using inner join. In this case, the report SQL may not be possible to complete on the database. If all conditions are false, a default value is returned. In the Source area, select a database instance for the database to access using Freeform SQL. 8 and up . In MicroStrategy SQL Generation Engine, non-aggregatable metrics are used for this kind of calculation. Sum <Distinct, FactID, UseLookupForAttributes>(Argument)Where: Argument is an attribute, fact, or metric representing a list of numbers. The maximum number of rows returned to the Server for the final result set. Example: Create a new custom subtotal object. There are three options available: No interaction - static custom group; Apply report filter to custom groupThis article notes how to remove LTRIM functions from SQL generated against OracleCa se functions Microstrategy Case functions return specified data in a SQL query based on the evaluation of user-defined conditions. 2 metric aggregations will not be dimensionality aware. Functions can be pushed down to. In MicroStrategy Developer, choose File > New > Report. This is an OLAP function. Although transformations can be applied to any attribute hierarchy, the Time hierarchy is used most often. There are two examples for each subsection, comparing the SQL syntax when the database performs the OLAP function calculations with the one when the Intelligence Server. KB17514: Using the 'Preserve all final pass result elements' VLDB property at attribute level in MicroStrategy SQL Generat… Number of Views 6. The Apply functions are not meant to take the place of the standard MicroStrategy functions. Write VLDB properties? VLDB stands for Very Large Data Base Properties. The SUM () function returns the total sum of a numeric column. Example include ApplySimple, ApplyComparison, etc. This property is found in the Select/Insert folder of the VLDB property editor: This property has four options: Group by expression. Pass-through expressions, also called Apply functions, allow use of special functions or syntactic constructs beyond what MicroStrategy can create on its own, but can be obtained through the relational database. The following list summarizes the metric-specific VLDB properties that can be set at the metric level. In that case, MicroStrategy accesses the partitioned data transparently by referring to a single table name. x does not parse the contents of the SQL string and it cannot anticipate differences in database implementations of standard (or nonstandard) functions. You can change VLDB properties to alter the syntax of a SQL statement and take advantage of database-specific optimizations. `Temporary view` intermediate table type VLDB settings is not applied in MicroStrategy when using Warehouse Partition Mapping Table. DataFrame. . Case. These are called pass-through functions because Microstrategy does not check the actual SQL construct and dumps it as is on the database. Multipass SQL statements in Freeform SQL are not supported in Microstrategy. Metric-specific VLDB properties in Microstrategy - Metric-specific VLDB properties in Microstrategy courses with reference manuals and examples pdf. expression is an expression of the exact numeric or approximate numeric data type category, except for the bit data type. (0 = time limit not enforced by this governing setting)MicroStrategy has a VLDB (Very Large Database) setting that can be configured to indicate the underlying database software does not support Full Outer Join operation. EXAMPLE: Consider a situation in which a metric must be created and that will sum values; however, it should only sum the values where an attribute tag is set to a desired value. They act as containers for non-standard SQL expressions that MicroStrategy does not support. Within a project, a security filter may be specified for any user. The following list of articles can be used for further reference regarding the 'derived table' behavior with MicroStrategy SQL engine. Or embed self-service capabilities for users to visualize key drivers or what-if scenarios. 6. Determines how distinct counts of values are retrieved from partitioned tables. Generally, when null checking is used in metrics, the null checking is performed as part of the initial metric calculation. You can use the SQL DISTINCT clause within the SQL SUM function. This function is commonly used in metrics and subtotals. The metric join type, described in the previous section, is not the only VLDB property that affects metrics. Reuses redundant SQL. Simple metrics always contain at least one aggregate function, such as sum or average, applied to a fact. The First option, 'CREATE and. The 'Create Individual Index' VLDB setting was introduced in MicroStrategy 8. Let us create one simple table named numbers and store the. Passes that hit the same fact table across different elements of a custom group are merged provided that they satisfy certain conditions. Right-click the Customer attribute and select New Attribute form. MicroStrategy value prompts do not allow multiple values. DAY_DATE DAY_DATE, a12. Other databases, such as some versions of Teradata, have a mix of the join standards and therefore need their own setting. 4. Note: To create custom expression qualifications, the advanced qualification option must be enabled in the report designer's preferences in MicroStrategy Desktop 8. From the Select a Project drop-down list, select the project for which to assign the security role. DATABASE INSTANCE. As you type, matching objects are displayed in a drop-down. g. x and 10. This article describes how MicroStrategy uses subqueries and how the options of the "Sub Query Type" VLDB property control the SQL syntax used. This function is commonly used in metrics and subtotals. This article notes a scenario where no aggregation occurs in the SQL generated by MicroStrategy. With VLDB properties correctly configured, a report can join to some lookup tables using outer join and others using inner join. Multiple passes are generated only when necessary to resolve all the metric definitions. For more information on the SUM() function, you can read this complete explanation of the SQL SUM() function. Place attributes Country and Distribution Center on report template, and the above metric either on report template, or in Report Objects window if you have an OLAP license. In the event of a code change in future builds, MicroStrategy may not be able to provide additional code on this matter even though this customization is provided. Select the Database Instance used for the project warehouse, right-click and select 'VLDB properties'. CAUSE: By checking the SQL statements of the report, there is no "sum" or "group by" statement. Generate report SQL (see the table below under ‘Without Setting’). The "Grouping" property has six possible settings, of which four specify non-aggregating behavior: Beginning (fact) Ending (fact)This issue has been classified as a defect by MicroStrategy. The following examples demonstrate how Level 1 and Level 2 SQL Global Optimization settings work in MicroStrategy SQL Generation Engine 9. The above example would not be valid with multiple months in the answer because the >= expects single values for its operands. Here’s the result: sum_quantity. MONTH_ID IN (#E1). You can click an object or continue to type. Tutorial project is used here. They act as containers for non-standard SQL expressions that MicroStrategy does not support. For complete details about all VLDB properties, see SQL Generation and Data Processing: VLDB Properties. A possible workaround is to change those VLDB properties from MicroStrategy Developer. Beginning with MicroStrategy SQL Engine 9.
