NQ_SESSION.ROLES is a session variable that returns a semicolon delimited string of roles assigned to the . If a semicolon must be included as part of a role name, precede the semicolon with a backslash character (\). You should test this SQL using the Test button in the [Repository|Session] Variable Initialization Block Data Source dialog. The Required for authentication option is dimmed, because this type of initialization block is executed after authentication. Unlike dynamic repository variables, session variables are not updated at scheduled time intervals. 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. If a semicolon must be included as part of a Catalog group name, precede the semicolon with a backslash character (\). Does Cast a Spell make you a spellcaster? There is no restriction on the number of values that the multi-source session variable can hold.

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). For repository variable initialization blocks, when you open a repository in online mode, the value shown in the Default initialization string field of the Initialization Block dialog is the current value of that variable as known to the Oracle BI Server. Data Concurrency, Data Science Function In the Administration Tool, select Manage, then select Variables. was shown. This allows the select statement to focus on just the data you want, rather than creating a view with potentially millions of rows and then subsequently applying a filter to that result set.

If a SQL initialization string for that database type has been defined when the initialization block is instantiated, this string is used. Cube Any legal SQL can be executed using an initialization block, including SQL that writes to the database or alters database structures, assuming the database permits the user ID associated with the connection pool to perform these actions. Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. Select this option to set session variables after the initialization block has populated the value (at user login) by calling the ODBC stored procedure NQSSetSessionValue(). rev2023.3.1.43269.
