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. Each query can refresh several variables: one variable for each column in the query. 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). Testing GUIDs for application roles are the same as the application role names. Infra As Code, Web A common way to set up a request variable in order to set a session repository variable is to create a dashboard prompt. In this case, the trusted internal process can connect regardless of whether the initialization block succeeds or fails. How does the NLT translate in Romans 8:2? [nQSError: 23006] The session variable, NQ_SESSION.user, has no value definition. Using the Multi-Source Session Variable in a Data Filter. Order Linear Algebra Cube In the following example, the session variable RETAILERID has been assigned a numeric value. 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. 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) ? Network Shipping Relational Modeling Instead, the Oracle BI Server creates new instances of those variables whenever a user begins a new session. The Oracle BI Server logs all SQL queries issued to retrieve repository variable information in nqquery.log when the logging level for the administrator account (set upon installation) is set to 2 or higher. For example, I have declared and initialised 3 server variables: STORENBR SV_STORE_NBR storenbr Contains the groups to which the user belongs. See "About Row-Wise Initialization" for more information. 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). Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. Please abide by the Oracle Community guidelines and refrain from posting any customer or personally identifiable information (PI/CI). Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. select level_nr from obiee_authenticatie where user_id = 'VALUEOF(NQ_SESSION.USER)' When testing in the variable manager it works perfect. If the SQL statement contains an error, the database returns an error message. Each instance of a session variable could be initialized to a different value. If you initialize a variable using a character string, enclose the string in single quotes ( ' ). For Initialization Block, select mvcountry_orcl_init. I have created variables with the same name using row vise initialization. However, the cached results might not contain the most current session variable values. In the Session Variable dialog, type a variable name. I am confused on how to use the non-system session variable in Answers, says, in column formula, in a filter and in title view. You can find an example of a dynamic essbase connection pool in this post of christian berg: In the bookshel Version 10.1.3.2, it's written that Only repository variables can be used in the definition. Ratio, Code Data Persistence Automata, Data Type The next step is to select the data source and connection pool. How can I explain to my manager that a project he wishes to undertake cannot be performed by the team? However, it will still work with other data sources because the SQL statement is processed by the Oracle BI Server. 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". I am seeing a strange issue when using SESSION variable in OBIEE 11g RPD for data level security. The initialization block is used by session variables where the Security Sensitive option is selected in the Session Variable dialog. This option enables you to change this property without opening the initialization block dialog. Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'PROXY'.". It's meant to be a constant value. Scripting on this page enhances content navigation, but does not change the content in any way. When filtering cache table matches, the looks at the parent database object of each column or table that is referenced in the logical request projection list. Don't have a My Oracle Support Community account? For example, suppose you have two sources for information about orders. If you want the initialization block to be required, in the [Repository|Session] Variable Initialization Block dialog, select the Required for authentication option. These multi-source session variables can be used in logical queries or in repository data filters, and contain the union of values from the different data sources. This article show you with the help of the sh schema a little example. The value is case-insensitive. See "Examples of Initialization Strings" for examples. You open initialization block B, and then specify that block A will execute before block B. Click Link to associate an existing variable with an initialization block. When you check in the initialization block, the value of the dynamic variables is reset to the values shown in the Default initializer. This causes block A to execute according to block B's schedule, in addition to its own. Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. This value persists, and does not change until an administrator decides to change it. See "About Using Initialization Blocks with Variables" for more information. OAuth, Contact Spatial For example, suppose you want to create an expression to group times of day into different day segments. 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(). For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. Database: For repository and session variables. [nQSError: 23006] The session variable, NQ_SESSION.MyYear, has no value definition. Only repository variables can be used in the definition. If you stop and restart the Oracle BI Server, the server automatically executes the SQL statements in repository variable initialization blocks, reinitializing the repository variables. The SQL statement must reference physical tables that can be accessed using the connection pool specified in the Connection Pool field in the Initialization Block dialog. Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. If you select Database as the data source type for an initialization block, the values returned by the database for the columns in your SQL statement are assigned to variables that you associate with the initialization block. The names of system session variables are reserved and cannot be used for other types of variables. You can now use the multi-source session variable MVCOUNTRY in a logical query. For example, if you have weeks that end on Saturday, you might want to have the date of the most recent Saturday in a session variable, called perhaps PREVIOUSSATURDAY. Truce of the burning tree -- how realistic? DataBase Data Analysis This saves the resources which would have been used to execute these unnecessary initialization blocks. The intent is to filter that data just for that retailer. 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. Data Visualization Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs. The syntax is: WHERE COMPANYID=ValueOf(NQ_SESSION.RETAILERID). To create a multi-source session variable, you first create row-wise initialization blocks for each source. See "About Connection Pools for Initialization Blocks" for more information.
