The presentation service can also send this error : Try to use the same letter case for the name of the variable (upper and lower). For session variable initialization blocks, you can select Row-wise initialization. See "Testing Initialization Blocks" for more information. A proxy user is a user that has been authorized to act for another user. You would initialize a session variable named Client, for example, that could be Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user. For the syntax, add NQ_SESSION if the variable is a session variable and see the relevant section for the function call. If you do not select a connection pool before typing the initialization string, you receive a message prompting you to select the connection pool.

Data Processing Legacy groups are mapped to application roles automatically. Infra As Code, Web To use row-wise initialization, create an initialization block and select the Row-wise initialization option (refer to "Creating Initialization Blocks"). I need to create a Dashboard, where I can fill out one Dashboard prompt and set some request variables, and then have the default values in another dashboard prompt, or the prompt for an analysis be based on the variables set in the first prompt. A repository variable has a single value at any point in time. There are a plethora of ways that dates can get formatted depending on which application is being used to select the dates. Used to enable or disable Oracle BI Server subrequest cache hits and seeding. Legacy groups are mapped to application roles automatically. Click OK to return to the Initialization Block dialog. In one of my report columns I need to get value of session variables like VALUEOF (NQ_SESSION.COLUMN1). In the dashboard prompt, when chosing 'server variable' as default selection, only NQ_SESSION.STORENBR results in the default value being set. 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. Why do you need to use session or request variables? For repository variables, you can specify the day, date, and time for the start date, as well as a refresh interval. In RPD, I created a new init block with session variable PRODUCT and row wise initialization is set. In the [Repository|Session] Variable Initialization Block dialog, click Edit Data Source.

OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? Using the Multi-Source Session Variable in a Logical Query. You use the same procedure to define nonsystem session variables as for system session variables. For example, you have Without using dynamic repository variables, you would describe the content of the source containing recent data with an expression such as: This content statement becomes invalid as new data is added to the recent source and older data is moved to the historical source. Debugging 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. Data Partition Please abide by the Oracle Community guidelines and refrain from posting any customer or personally identifiable information (PI/CI). In online mode, Initialization Block tests do not work with connection pools set to use :USER and :PASSWORD as the user name and password.

Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. 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. Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. In the body, insert detailed information, including Oracle product and version. Add is only available if there are initialization blocks that have not yet been selected. Values can still be added to the multi-source session variable from other component initialization blocks that succeed in returning values. If you selected Custom Authenticator for your data source type, perform the following steps: Click Browse to select an existing custom authenticator, or click New to create one. Why is the error occurring only for User B? If there are more variables than columns, the additional variables are not refreshed (they retain their original values, whatever they may be).

The multi-source session variable will fail only if all of the component initialization blocks return null values. Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. In the Session Variable dialog, type a variable name. 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. In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. Contains the application roles to which the user belongs. There seems to be a glitch in the way obiee (11.1.1.6.0) interprets server variables when using them as default values for a dashboard prompt: only when the variable name is in uppercase and contains no underscores will it be recognised. See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. Otherwise, the default initialization SQL for the database type is used. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. There are three cases to consider, depending on whether the session variable is intended to filter a column that has a numeric, varchar, or date data type. This variable has a possible value of 0 or 1. Initializing Dynamic Repository Variables. For example, an initialization block might use the function pi(), which is specific to SQL Server. When using external table authentication with Delivers, the portion of the SQL statement that makes up the :PASSWORD constraint must be embedded between NQS_PASSWORD_CLAUSE clauses. Used to enable or disable Oracle BI Server result cache seeding. The Required for authentication option is selected in the Session Variable Initialization Block dialog. It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. OBIEE - Connection Pool: The picture below show a repository variable call but you can use in the same way the session variable syntax. Used to enable or disable Oracle BI Server subrequest cache hits and seeding. See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information.

Lexical Parser Contains a description of the user, typically populated from the LDAP profile of the user. Allow deferred execution. This variable has a possible value of 0 or 1. The string you enter here is processed by the Oracle BI Server, and therefore as long as it is supported by the Oracle BI Server, the string will work with different data sources. There is no restriction on the number of values that the multi-source session variable can hold. You also set up a schedule that the Oracle BI Server will follow to execute the query and periodically refresh the value of the variable. In the Administration Tool, select Manage, then select Variables. Holds the value the user enters. The value is case-insensitive. Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Presentation Services. You need to describe the content of these sources on the Content tab of the Logical Table Source dialog. 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. File System Design Pattern, Infrastructure 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. (HY000) SQL Issued: SET VARIABLE MYYEAR='1998';SELECT TIMES_VIEW.calendar_year saw_0 FROM Test ORDER BY saw_0 Try to use the same letter case for the name of the variable (upper and lower).
