Rather than entering the numbers 17 and 23 into this expression as constants, you could use the Variable tab of the Variable dialog to set up a static repository variable named prime_begin and initialize it to a value of 17, and create another variable named prime_end and initialize it to a value of 23. The syntax is: WHERE COMPANYID=ValueOf(NQ_SESSION.RETAILERID). How can the mass of an unstable composite particle become complex? Create an Agent with OBIEE Analytics Agents enable you to automate your business processes. Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. Execution of session variable initialization blocks cannot be deferred in some circumstances. The call for a session variable is: VALUEOF("NQ_SESSION.Variable Name") Data Persistence It will not change unless you change it. Data Structure You can find the nqquery.log file in: For more information about user-level logging, see "Managing the Query Log" in Oracle Fusion Middleware System Administrator's Guide for Oracle Business Intelligence Enterprise Edition. Data Science Selector Network For example, the following CASE statement is identical to the one explained in the preceding example, except that variables have been substituted for the constants: You cannot use variables to represent columns or other repository objects. It seems that OBIEE save the default initializer value in the same space than for a repository variable. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. Data Persistence When the value of a dynamic repository variable changes, all cache entries associated with a business model that reference the value of that variable are purged automatically. Versioning This section contains the following topics: The value of a static repository variable is initialized in the Variable dialog. In addition, if an initialization block fails for a particular connection pool during Oracle BI Server start-up, no more initialization blocks using that connection pool are processed.

Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. When a repository has multiple initialization blocks, you can set the order (establish the precedence) in which the blocks will be initialized. In the Browse dialog, select the blocks that should be initialized before the block that you have open, and then click OK.

WHERE upper(SALESREP) = upper('valueof(NQ_SESSION.USER)'). A repository variable has a single value at any point in time. 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. Data (State) Data Warehouse This behavior ensures that you cannot use the same connection pool for initialization blocks that you use for queries. The icon for an initialization block is a cube labeled i. If the administrator user (defined upon install) has a Logging level defined as 4 and the session variable LOGLEVEL defined in the repository has a value of 0 (zero), the value of 0 applies. The other two can not be addressed it seems, I have tried variations: The same goes for default selection type 'variable expression': the expected result is achieved when using @{biServer.variables['NQ_SESSION.STORENBR']}, yet no such luck using: @{biServer.variables['NQ_SESSION.SV_STORE_NBR']}, @{biServer.variables['NQ_SESSION.

See Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. An error will generate if a session variable is used. Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs. See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information. In the Administration Tool, select Manage, then select Variables. If you want the query for an initialization block to have database-specific SQL, you can select a database type for that query. variables is plural. Not the answer you're looking for? Used to enable or disable Oracle BI Server result cache hits. For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. Cube However, it will still work with other data sources because the SQL statement is processed by the Oracle BI Server. Browser Cube Log, Measure Levels You can also use this variable in a SQL statement. If any of the row-wise initialization blocks returns null results, this is logged in the Oracle BI Server log, nqserver.log. Data Warehouse If the SQL statement contains an error, the database returns an error message. 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. To associate variables with initialization blocks: In the Variable Manager dialog, double-click the initialization block you want to edit. Used for Oracle BI Presentation Services. "storenbr"), What am I missing? Order For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user.

The value of LOGLEVEL (a number between 0 and 5) determines the logging level that the Oracle BI Server uses for user queries. If you order a special airline meal (e.g. Such directories begin with sk_. Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. The presentation service can also send this error : Try to use the same letter case for the name of the variable (upper and lower). See "Testing Initialization Blocks" for more information. Values in repository and session variables are not secure, because object permissions do not apply to variables. If you select this option, execution of the initialization block is deferred until an associated session variable is accessed for the first time during the session. This option prevents execution of all session variable initialization blocks during the session logon stage, giving a shorter logon time. OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? What are some tools or methods I can purchase to trace a water leak?

Compiler Select this option to identify the variable as sensitive to security when using a row-level database security strategy, such as a Virtual Private Database (VPD). While the initialization block is checked out, the Oracle BI Server may continue to refresh the value of dynamic variables refreshed by this initialization block, depending on the refresh intervals that are set. If the database object has the Virtual Private Database option selected, the Oracle BI Server matches a list of security-sensitive variables to each prospective cache hit. For example, the format of a date report variable can vary, depending on whether the user has changed the default value set by a dashboard calendar prompt. Then, enter its associated string. See "Examples of Initialization Strings" for additional examples. The number of associated variables can be different from the number of columns being retrieved. At run time, if an initialization string for the database type has been defined, this string is used. About Using Initialization Blocks with Variables, Associating Variables with Initialization Blocks, When Execution of Session Variable Initialization Blocks Cannot Be Deferred, Enabling and Disabling Initialization Blocks. For example, to filter a column on the value of the dynamic repository variable CurrentMonth, set the filter to the variable CurrentMonth.

Dom Because of this, if your repository has been upgraded from a previous release, you may see warnings in the Consistency Checker similar to the following: If you see warnings similar to this, update the relevant static repository variables so that the default initializers have constant values. Making statements based on opinion; back them up with references or personal experience. This section explains how to create session variables. It is recommended that you create a dedicated connection pool for initialization blocks where you select Database as the data source type.
