To use row-wise initialization, create an initialization block and select the Row-wise initialization option (refer to "Creating Initialization Blocks"). OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? ':PASSWORD' (note the colon and the single quotes) is the password the user enters. 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 (State) However, if you select Use OBI EE Server, the query is rewritten by the Oracle BI Server for the appropriate database. Html Url To select a data source and connection pool for initialization blocks: In the Variable Manager dialog, double-click the initialization block you want to edit. Number For session variable initialization blocks, you can also select LDAP Server or Custom Authenticator. The SQL SELECT statement in the Default initializer list can contain multiple columns. There are two types of session variables: system and nonsystem. It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. Used for Oracle BI Presentation Services. If a semicolon must be included as part of a role name, precede the semicolon with a backslash character (\). Don't forget the quotes which enclose the Variable Name. In previous releases, the Administration Tool did not limit the values of default initializers for static repository variables. I try to display the variable by define it in column formula as VALUEOF(NQ_SESSION. If these date prompts are setting report variables, you need to be able to deal with both formats. While the component session variables appear in the Variable Manager, the multi-source session variable that has been created, MVCOUNTRY, will appear in Expression Builder. You cannot use any other value or expression as the default initializer for a static repository variable. GUIDs for application roles are the same as the application role names. Data Science Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. The presentation service can also send this error : Try to use the same letter case for the name of the variable (upper and lower). Table 19-2 shows the table in this example. The table describes the available system session variables. You can set execution precedence and deferred execution with multi-source session variables, similar to regular session variables. Oracle BI, Names for all variables should be unique. In the [Repository|Session] Variable Initialization Block dialog, click Edit Data Source. Example message: "The execution of init block 'A_blk' cannot be deferred as it is using row-wise initialization.". SELECT DISTINCT 'PRODUCT', product_id FROM BI_SECURITY WHERE UPPER(USER_ID) = UPPER(':USER'), #business-intelligence-suite-enterprise-edition-obiee. After they are created, variables are available for use in Expression Builder. 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 Each instance of a session variable could be initialized to a different value. Based on products assigned to user in security table, data filter is applied. When a user belongs to multiple roles, include the role names in the same column, separated by semicolons (for example, RoleA;RoleB;RoleC). If you initialize a variable using a character string, enclose the string in single quotes ( ' ). You can then use the SQL IN operator to test for values in a specified list. 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. Data Structure This option is for session variable initialization blocks only. If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. Failure to execute can occur if the wrong credentials have been defined in the initialization block, or if there is an error in the default initialization string. You can then use that session variable as the default date value in your queries for example, Periods.Date = VALUEOF(NQ_SESSION.PREVIOUSSATURDAY). The approach Ive used, which is not ideal but has worked for me, is to hedge your bets in the Select statements. Css "storenbr"), What am I missing? Computer The Oracle BI Server can also provide functions (such as PI) that might not be available in the data source, and the SQL statement will work with other data sources supported by the Oracle BI Server (for example, ADF, SQL Server, Oracle, and XML files). Exists only for compatibility with previous releases. Quick question, a colleague of mine was telling me that the session variable, NQ_SESSION.GROUP, only shows groups which are assigned at the presentation >> level (or passed in from LDAP or other data source) but it does not show any of the group assignments made within the RPD itself. Cache hits would only occur on cache entries that included and matched all security-sensitive variables. Story Identification: Nanomachines Building Cities, Ackermann Function without Recursion or Stack. 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. For example, this option lets non-administrators to set this variable for sampling. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. For session variable initialization blocks, you can select Row-wise initialization. In the Select Connection Pool dialog, select the connection pool and click Select. 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. 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. You do not need to set up the PASSWORD variable, and you can use this variable in a database connection pool to allow passthrough login using the user ID and password of the user. Learn about session variables and how to create them. The value is case-insensitive. 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.

An error will generate if a session variable is used in the opaque view. 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. Nominal 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. Used to enable or disable Oracle BI Server plan cache hits. It's meant to be a constant value. This variable has a possible value of 0 or 1. Lexical Parser Privacy Policy I try to display the variable by define it in column formula as VALUEOF (NQ_SESSION."ABC") but error message "The session variable, NQ_SESSION.ABC, has no value definition." was shown. OBIEE - BI Server Patch (automatic update with a patch file) Required for authentication. 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. For example, suppose a repository has two initialization blocks, A and B. Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs. The next step is to select the data source and connection pool. Graph The NQ_SYSTEM initialization block name is reserved. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. Distance Contains the groups to which the user belongs. 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) ? Data Analysis 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. (Apart from the obvious answer: it's a bug. 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. Log, Measure Levels You initialize dynamic repository variables in the same way as static variables, but the values are refreshed by data returned from queries. The SQL statement used to refresh the variable must reference physical tables that can be accessed through the connection pool specified in the Connection Pool field. OAuth, Contact If you select this option, this initialization block must succeed for users to log in. Holds the Oracle BI Presentation Services user interface display language. You open initialization block B, and then specify that block A will execute before block B. (Session init blocks only) Select an option. In the Session Variable dialog, type a variable name. I have tried using the Variable Expression option to set the default values in the prompts, but it only uses the values of the session variables, not the temporary values in the request variables. At run time, if an initialization string for the database type has been defined, this string is used. Users can select a language on the sign-in page for Oracle BI EE, or they can change the language setting on the Preferences tab of the My Account dialog after signing in. Used to enable or disable Oracle BI Server result cache hits. Holds the name of the proxy user. 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. 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.
