WHERE upper (SALESREP) = upper ('valueof (NQ_SESSION.USER)') The third case, dates, is the hardest. Infra As Code, Web You can also right-click an existing initialization block in the Variable Manager and choose Disable or Enable. Url There are many times when it is very beneficial to pass the value of session variables (or report variables) into the SQL used to define a Select table in the physical layer. Selector You open initialization block B, and then specify that block A will execute before block B. The first case is where a session variable has a numeric value. In addition to supporting regular session variables that are populated from one data source, Oracle Business Intelligence also supports session variables that can be populated from multiple data sources. Data Structure Contains the groups to which the user belongs. Session variables are created and assigned a value when each user logs on. Does Cosmic Background radiation transmit heat? You do not need to set up the PASSWORD variable, and you can use this variable in a database connection pool to allow passthrough login using the user ID and password of the user. . The multi-source session variable will fail only if all of the component initialization blocks return null values. Ratio, Code Log, Measure Levels Business Intelligence Server Enterprise Edition - Version 12.2.1.0.0 to 12.2.1.4.200414 [Release 12g]: OBIEE 12c - case sensitivity of USER session variable name OBIEE 12c - case sensitivity of . Ratio, Code While the main focus of this section is on the definition and usage of multi-source session variables, you may also select the VALUEOF the component session variables in logical queries and data filters. In the Data Filters tab, create the data filter expression: Note that the Expression Builder, as shown in the image that follows, displays only the multi-source session variable MVCOUNTRY, and not the regular session variables that were used during the creation of the multi-source session variable. https://docs.oracle.com/cd/E28280_01/bi.1111/e10540/variables.htm#BIEMG3104 Share Improve this answer Follow The value of LOGLEVEL, a number between 0 and 5, determines the logging level that the Oracle BI Server uses for user queries. Tree If you do not select a connection pool before typing the initialization string, you receive a message prompting you to select the connection pool. In the dashboard prompt, when chosing 'server variable' as default selection, only NQ_SESSION.STORENBR results in the default value being set. Select a discussion category from the picklist. When filtering cache table matches, the Oracle BI Server looks at the parent database object of each column or table that is referenced in the logical request projection list. If you selected Use database specific SQL, then in the Database pane, expand and select the database. You can then use that session variable as the default date value in your queries for example, Periods.Date = VALUEOF(NQ_SESSION.PREVIOUSSATURDAY). OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? This section contains the following initialization string examples: Example 19-1, "A SQL Statement When Site Uses Delivers", Example 19-2, "A SQL Statement When Site Does Not Use Delivers", Example 19-3, "A SQL Statement Joining Tables From Multiple Data Sources - When Using the 'OBI EE Server' Setting", Example 19-1 A SQL Statement When Site Uses Delivers. The default location for the nqquery.log file is: You can use the row-wise initialization option to create session variables dynamically and set their values when a session begins. Design Pattern, Infrastructure The icon for an initialization block is a cube labeled i. Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. It identifies the default dashboard the user sees when logging in (the user can override this preference after logged on). To accurately reflect the new content of the recent source, you would have to modify the fragmentation content description manually. The NQ_SYSTEM initialization block name is reserved. In the [Repository|Session] Variable Initialization Block dialog, type a name for the block. Note that the recommended practice is to use application roles rather than Catalog groups. Only repository variables can be used in the definition. If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? The query returns data only if the user ID and password match values found in the specified table. See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information. Dimensional Modeling Used to enable or disable Oracle BI Server subrequest cache hits and seeding. The next step is to associate variables with the initialization block. Static repository variables must have default initializers that are either numeric or character values. I have created variables with the same name using row vise initialization. Names for all variables should be unique. Javascript Web Services If you select this option, this initialization block must succeed for users to log in. You can edit Repository initialization blocks, or Session initialization blocks. In addition, you can use Expression Builder to insert a constant as the default initializer, such as Date, Time, and TimeStamp. Collection The names of system session variables are reserved and cannot be used for other types of variables. This option enables you to change this property without opening the initialization block dialog. The deferred execution of an initialization block also triggers the execution of all unexecuted predecessor initialization blocks. Holds the value the user enters. Table 19-2 Sample Session Variables Database Table. This SQL contains two constraints in the WHERE clause: ':USER' (note the colon and single quotes) is the ID the user types when logging in. See "Setting Administration Tool Options" for more information. In the Variable Manager dialog, select Action > New > Repository > Variable. Statistics Used to enable or disable Oracle BI Server plan cache hits. Data Quality Trigonometry, Modeling Mathematics The Oracle BI Server logs all SQL queries issued to retrieve session variable information if the logging level is set to 2 or higher in the Identity Manager User object, or the LOGLEVEL system session variable is set to 2 or higher in the Variable Manager. The table describes the available system session variables. At run time, if an initialization string for the database type has been defined, this string is used. Another suggested use for dynamic repository values is in WHERE clause filters of logical table sources, defined on the Content tab of the Logical Table Source dialog. Learn about session variables and how to create them. You can set execution precedence and deferred execution with multi-source session variables, similar to regular session variables. Create a second session variable called MVCOUNTRY____ORCL, making sure to include four underscores between the variable name and the source name. The left pane displays a tree that shows variables and initialization blocks, and the right pane displays details of the item you select in the left pane. For Oracle, you could write: trunc(sysdate) - to_char(sysdate,'D')+1 CurrentSunday, , trunc(sysdate) - to_char(sysdate,'D')+2 CurrentMonday, , trunc(sysdate) - to_char(sysdate, 'D')+7 CurrentSaturday, , trunc(sysdate) - to_char(sysdate,'D')+8 NextSunday, , trunc(sysdate) - to_char(sysdate,'D') PreviousSaturday, , trunc(sysdate) - to_char(sysdate,'D')+2-8 PreviousSunday, , trunc(sysdate) - to_char(sysdate,'D')+2-7 PreviousMonday, , cast(to_char(trunc(sysdate), 'YYYY') as INT) CurrentYear, , Cast(to_char(trunc(sysdate), 'YYYY')-1 as INT) PreviousYear, , add_months(trunc(last_day(sysdate)),-1) + 1 CurrentMonthFirstDay, , last_day(trunc(sysdate)) CurrentMonthLastDay, , add_months(TRUNC(last_day(sysdate)),-2) + 1 PreviousMonthFirstDay, , case when last_day(SYSDATE) = SYSDATE then TRUNC(SYSDATE) else add_months(TRUNC(last_day(sysdate)),-1) end LASTDAYCOMPLETEMONTH. Dynamic repository variables are useful for defining the content of logical table sources. Don't have a My Oracle Support Community account? When the user modifies the date range using the first calendar, the format of the first date changes. biServer is good where biserver is not good. This causes block A to execute according to block B's schedule, in addition to its own. This is another system variable whose presence is always assumed when the USER system session variable is used. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. Browser This option prevents execution of all session variable initialization blocks during the session logon stage, giving a shorter logon time. However, it will still work with other data sources because the SQL statement is processed by the Oracle BI Server. For Initialization Block, select mvcountry_orcl_init. Create a row-wise initialization block called mvcountry_sebl_init with the following SQL for Default initialization string: Create a second row-wise initialization block called mvcountry_orcl_init with the following SQL for Default initialization string: Still in the Variable Manager, select Action > New > Session > Variable. Contains the application roles to which the user belongs. The Required for authentication option is dimmed, because this type of initialization block is executed after authentication. Data Type Computer Cryptography Process (The NQ_SYSTEM initialization block name is reserved.). If you select Row-wise initialization, the Use caching option becomes available. When Jane connects to the Oracle BI Server, her session contains three session variables from row-wise initialization: LEVEL, containing the value 8; STATUS, containing the value FULL-TIME; and GRADE, containing the value AAA. Data Persistence If you want the initialization block to be required, in the [Repository|Session] Variable Initialization Block dialog, select the Required for authentication option. Using the convention that weeks begin on Sunday (adjust accordingly if thats not the case for your enterprise), we can think of Current, Previous, and Next weeks. Table 19-1 describes the available system session variables. See "About Connection Pools for Initialization Blocks" for more information. A common use for nonsystem session variables is setting user filters. OBIEE offer several variables which can be set : variables from the OBIEE Server known as session and repository variables.
