Data Concurrency, Data Science Text If this option is not selected, then the variable cannot be set. When you select the Use OBI EE Server option, there is no need for a connection pool, because the SQL statement is sent to the Oracle BI Server and not directly to the underlying database. CREATE TABLE OBIEE_PROXY_USER ( PROXYID VARCHAR2 (100) NOT NULL, TARGETID VARCHAR2 (100) NOT NULL, PROXYLEVEL VARCHAR2 (100) NOT NULL) Insert some data : Create Session Variables for Proxy Functionality (inside the repository) Modify the instanceconfig.xml File for Proxy Functionality Here comes the more tricky parts The names of system session variables are reserved and cannot be used for other types of 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. Used for Oracle BI Presentation Services.

OBIEE offer several variables which can be set : variables from the OBIEE Server known as session and repository variables. Does Cosmic Background radiation transmit heat? Each query can refresh several variables: one variable for each column in the query. Data Structure It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. 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. Holds the value the user enters. To associate variables with initialization blocks: In the Variable Manager dialog, double-click the initialization block you want to edit. Logical Data Modeling 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. The new value is only valuable for the query. Used to enable or disable Oracle BI Server plan cache seeding. COLUMN1 is having values VARIABLE1 , VARIABLE2 etc .

You use the same procedure to define nonsystem session variables as for system session variables. This logical WHERE clause expands into a physical IN clause, as shown in the following statement: See "About Using Initialization Blocks with Variables" for more information about initialization blocks. System session variables have reserved names that cannot be used for other kinds of variables such as static or dynamic repository variables and nonsystem session variables. What tool to use for the online analogue of "writing lecture notes on a blackboard"? Statistics Http I need it to be the values of TestVar1 and TestVar3, that were applied in a previous prompt as request variables, multiplied, but all I get is the original values from the session variables. A repository variable has a single value at any point in time. Data Analysis You can only test this SQL statement using the Test button in the [Repository|Session] Variable Initialization Block Data Source dialog when in online mode. Tags: You can then use that session variable as the default date value in your queries for example, Periods.Date = VALUEOF(NQ_SESSION.PREVIOUSSATURDAY). You can use a variable to specify the names of catalog and schema objects. In the logical table source TIMES Fact from the logical fact table Times, let's fill in the where clause with the repository session variable. In the [Repository|Session] Variable Initialization Block Data Source dialog, click Test. Security When a user belongs to multiple roles, include the role names in the same column, separated by semicolons (for example, RoleA;RoleB;RoleC).

User A was able to login to OBIEE presentation and see assigned product ID's being filtered in the report. Click Link to associate an existing variable with an initialization block. To create a multi-source session variable, you first create row-wise initialization blocks for each source. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. Another suggested use for dynamic repository values is in WHERE clause filters of logical table sources, defined on the Content tab of the Logical Table Source dialog. There are two "flavors" of system variables: System session variables: User ID, the user's data security groups, and the user's web catalog group(s) are all examples of system . Identifies the query as a SELECT_PHYSICAL query. System session variables are session variables that the Oracle BI Server and Oracle BI Presentation Services use for specific purposes. Status. Select a discussion category from the picklist. 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. Browser Order Example 19-2 A SQL Statement When Site Does Not Use Delivers. This variable has a possible value of 0 or 1. OBIEE - Connection Pool: The picture below show a repository variable call but you can use in the same way the session variable syntax. Data Persistence The next step is to associate variables with the initialization block. Why must a product of symmetric random variables be symmetric? Unlike dynamic repository variables, session variables are not updated at scheduled time intervals. The query works because when you select the Use OBI EE Server option, the query is rewritten by the BI Server for the specified data sources. In the Application Role dialog, click Permissions.

This SQL statement contains two constraints in the WHERE clause: ':USER' (note the colon and the single quotes) is the ID the user types when logging in. When you create SQL and submit it directly to the database (for example, when using database-specific SQL in initialization blocks), the SQL statement bypasses the Oracle BI Server. How can I explain to my manager that a project he wishes to undertake cannot be performed by the team? An error will generate if a session variable is used in the opaque view. 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 values remain unchanged for the duration of the session. Privacy Policy ), #business-intelligence-suite-enterprise-edition-obiee. In the Data Filters tab, create the data filter expression: Note that the Expression Builder, as shown in the image that follows, displays only the multi-source session variable MVCOUNTRY, and not the regular session variables that were used during the creation of the multi-source session variable. Versioning Using the Multi-Source Session Variable in a Logical Query. Static repository variables must have default initializers that are either numeric or character values.

The Required for authentication option is selected in the Session Variable Initialization Block dialog. Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Server. Lexical Parser Log, Measure Levels Anybody who knows or can guess the name of the variable can use it in an expression in Answers or in a Logical SQL query. How can the mass of an unstable composite particle become complex? A common use for nonsystem session variables is setting user filters. (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. If you do not want this to occur, use the Undo Check Out option. This variable has a possible value of 0 or 1. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. The order of the columns in the SQL statement and order of the variables associated with the initialization block determine the column value that is assigned to each variable. If there are fewer variables than columns, extra column values are ignored. Please abide by the Oracle Community guidelines and refrain from posting any customer or personally identifiable information (PI/CI). For session variable initialization blocks, you can also select LDAP Server or Custom Authenticator. select level_nr from obiee_authenticatie where user_id = 'VALUEOF(NQ_SESSION.USER)' When testing in the variable manager it works perfect.
