This variable has a possible value of 0 or 1. There are two types of session variables: system and nonsystem. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. Browser When a user belongs to multiple roles, include the role names in the same column, separated by semicolons,for example, RoleA;RoleB;RoleC. Holds the Oracle BI Presentation Services user interface display language. Don't forget the quotes which enclose the Variable Name.

Data Concurrency, Data Science For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. With the version 10.1.3.4, a warning is generated: But BI Server process it without problem. It seems that OBIEE save the default initializer value in the same space than for a repository variable. Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user.

This article gives an How-to : OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? The Variable Manager dialog has two panes. You can use the Variable Manager in the Administration Tool to enable and disable initialization blocks. For this example, you would provide the following SQL statement for the initialization string: Note that NQ_SESSION.USERID has already been initialized using another initialization block. When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC).

The values of dynamic repository variables are set by queries defined in the Default initialization string field of the Initialization Block dialog. Dates are, frankly, inordinately messy in OBIEE. Nominal Function See "About Row-Wise Initialization" for more information. The only way I can actually address the other two values to set the default value, is through the default selection type 'sql result', in which I look up the variable value using the dimension to which it refer: WHERE "dimension". If these date prompts are setting report variables, you need to be able to deal with both formats. Data Partition One source contains recent orders and the other source contains historical data. The following example illustrates how to create and use a multi-source session variable: In the Variable Manager in the Administration Tool, select Action > New > Session > Initialization Block. I try to display the variable by define it in column formula as VALUEOF (NQ_SESSION."ABC") but error message "The session variable, NQ_SESSION.ABC, has no value definition." was shown. To add a Default initializer value, type the value in the Default initializer box, or click the Expression Builder button to use Expression Builder. This happens automatically when you double-click the variables to paste them into the expression. The Required for authentication option is selected in the Session Variable Initialization Block dialog. The names and values of the session variables reside in an external database that you access through a connection pool. Testing The names of system session variables are reserved and cannot be used for other types of variables. By default, when you open the Initialization Block dialog for editing in online mode, the initialization block object is automatically checked out. The presentation service can also send this error : Try to use the same letter case for the name of the variable (upper and lower). "store number" = VALUEOF(NQ_SESSION. Allow deferred execution. The next step is to establish execution precedence. This variable has a possible value of 0 or 1. Values in repository and session variables are not secure, because object permissions do not apply to variables. In other words, if you change the SQL Server back-end database to Oracle, the query will still work. In the [Repository|Session] Variable Initialization Block Variable Target dialog, perform one of the following steps: Associate variables with the initialization block by doing one of the following: Click New, and in the Variable dialog, create a new variable. OBIEE - Where can I use a BI Server variable (session/repository) ? Data Quality Expression Builder pastes it into the expression at the active cursor insertion point. Required for authentication. The above query example in the initialization block uses a join query with multiple tables from different data sources (for example, SQLServer, Oracle and XML Files). Data Concurrency, Data Science Network Monitoring In the following example, the session variable RETAILERID has been assigned a numeric value.

If you want the initialization block to be required, in the [Repository|Session] Variable Initialization Block dialog, select the Required for authentication option. 2. If you can get to set a number request variable because it always add quotes, it's a bug because the value is independent from the data type of your presentation variable (works for the version 10.3.4.1). A common use of these variables is to set filters for use in Oracle BI Presentation Services. See "Creating Initialization Blocks" for more information. Init block 'B_blk' does not have "Allowed deferred execution" flag set. For static repository variables, the value you specify in the Default initializer window persists. See "Creating Repository Variables" or "Creating Session Variables" for information about creating variables.

You can set execution precedence and deferred execution with multi-source session variables, similar to regular session variables. In RPD, I created a new init block with session variable PRODUCT and row wise initialization is set. When the execution of session variable initialization blocks cannot be deferred, a message is displayed that explains why. BETWEEN case when substr('valueof(NQ_SESSION. You use the same procedure to define nonsystem session variables as for system session variables.

Repository variables can be used instead of literals or constants in Expression Builder in the Administration Tool. Select Row-wise initialization. The initialization block is used to set your session variable to a dynamic value. Process The values remain unchanged for the duration of the session. Cache hits would only occur on cache entries that included and matched all security-sensitive variables. Security Sensitive. To learn more, see our tips on writing great answers. For example, using the table values in the previous example, you would type the following SQL statement for the initialization string: This SQL statement populates the variable LIST_OF_USERS with a list, separated by colons, of the values JOHN and JANE (for example, JOHN:JANE).

It identifies the default dashboard the user sees when logging in (the user can override this preference after logged on). You can then use that session variable as the default date value in your queries for example, Periods.Date = VALUEOF(NQ_SESSION.PREVIOUSSATURDAY). In addition, you can use Expression Builder to insert a constant as the default initializer, such as Date, Time, and TimeStamp. If you are using a calendar thats different from the normal Gregorian calendar (i.e. vegan) just to try it, does this inconvenience the caterers and staff? Number Values can still be added to the multi-source session variable from other component initialization blocks that succeed in returning values. Holds the value the user enters as his or her logon name. You should test the SQL statement using the Test button or a SQL tool such as the Oracle BI Client utility. Click here to get started. Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs. Data Warehouse Is there a reason you can't use user variable? Then, you explicitly define session variables for each source. See "When Execution of Session Variable Initialization Blocks Cannot Be Deferred" for more information.
