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. Css The values of dynamic repository variables are set by queries defined in the Default initialization string field of the Initialization Block dialog. If you selected LDAP Server for your data source type, perform the following steps: Click Browse to select an existing LDAP Server, or click New to open the General tab of the LDAP Server dialog and create an LDAP Server. 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). Data Analysis Distance The third case, dates, is the hardest. Data Warehouse To enable or disable an initialization block: In the Administration Tool, select Manage, then select Variables.

The syntax is: WHERE COMPANYID=ValueOf (NQ_SESSION.RETAILERID) The second case is where a session variable needs to be evaluated as a string. 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 value is case-insensitive. (Optional) Click Test to test the data source connectivity for the SQL statement. However, the cached results might not contain the most current session variable values. For example, suppose a repository has two initialization blocks, A and B. Holds the name of the proxy user. The second case is where a session variable needs to be evaluated as a string. For example, I have declared and initialised 3 server variables: STORENBR SV_STORE_NBR storenbr If you order a special airline meal (e.g. The repository variable, NQ_SESSION.MyYear, has no value definition. Data Structure See "Examples of Initialization Strings" for additional examples. It is also saved as the author field for catalog objects. Then, you explicitly define session variables for each source. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. You can also use this variable in a SQL statement. You can also right-click an existing initialization block in the Variable Manager and choose Disable or Enable.
