To reorder variables, select a variable and click Up or Down. You can get this warning when you perform a check global consistency. OBIEE - Where can I use a BI Server variable (session/repository) ? DataBase Using the Multi-Source Session Variable in a Logical Query. StartDate)', 1, 3) = '201' then to_date(substr('valueof(NQ_SESSION.StartDate)',1,10), 'yyyy-mm-dd')else to_date('valueof(NQ_SESSION.StartDate)', 'mm/dd/yyyy') end AND case when substr('valueof(NQ_SESSION.EndDate)', 1, 3) = '200' or substr('valueof(NQ_SESSION.EndDate)', 1, 3) = '201' then to_date(substr('valueof(NQ_SESSION.EndDate)',1,10), 'yyyy-mm-dd')else to_date('valueof(NQ_SESSION.EndDate)', 'mm/dd/yyyy') end, Tags: Then, you explicitly define session variables for each source. This variable has a possible value of 0 or 1. For Initialization Block, select mvcountry_orcl_init. You can also use the row-wise initialization option to initialize a variable with a list of values. To create a session variable: In the Administration Tool, select Manage, then select Variables. For this example, you would provide the following SQL statement for the initialization string: Note that NQ_SESSION.USERID has already been initialized using another initialization block. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. Infra As Code, Web When the user logs in to act as some other user, the value of the USER session variable matches the USERID the user is acting as. Used to enable or disable Oracle BI Server result cache seeding. I have defined non-system session variable, says ABC in RPD, and would like to use it in Answers. You won't be able to use the Oracle date functions for many of the values you want, but you can still write the SQL to return the values according to the fiscal periods in your calendar using different methods. The third case, dates, is the hardest. Holds the value the user enters. 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. Cryptography (Apart from the obvious answer: it's a bug. Is there any way to do this? (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. You should test the SQL statement outside of the Oracle BI Server, substituting valid values for the USER and PASSWORD variables. COMPANYID is the name of a physical column. In the [Repository|Session] Variable Initialization Block Execution Precedence dialog, click Add. "SV_STORE_NBR"']}, @{biServer.variables['NQ_SESSION.storenbr']}, @{biServer.variables['NQ_SESSION."storenbr"']}. In the Variable Manager dialog, double-click the last initialization block that you want to be initialized. See "About Connection Pools for Initialization Blocks" for more information. For session variable initialization blocks, you can also select LDAP Server or Custom Authenticator. This behavior ensures that you cannot use the same connection pool for initialization blocks that you use for queries. data for multiple clients and you structured the database so that data for each client was in a Dates are, frankly, inordinately messy in OBIEE. Learn about session variables and how to create them. Debugging The values of dynamic repository variables are set by queries defined in the Default initialization string field of the Initialization Block dialog. If this option is not selected, then the variable cannot be set. Could anyone please advise? Since you are going to be setting these date variables using physical SQL in initialization blocks, the SQL issued will be specific to the database platform you are using. Contains a description of the user, typically populated from the LDAP profile of the user. Dom Holds the name of the proxy user. WHERE upper(SALESREP) = upper('valueof(NQ_SESSION.USER)'). It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. System session variables are session variables that the Oracle BI Server and Oracle BI Presentation Services use for specific purposes. 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(). Operating System 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. Process In the body, insert detailed information, including Oracle product and version. You should test this SQL using the Test button in the [Repository|Session] Variable Initialization Block Data Source dialog. In the Identity Manager dialog, in the tree pane, select BI Repository. If you can get to set a number request variable because it always add quotes, it's a bug because the value is independent from the data type of your presentation variable (works for the version 10.3.4.1). 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. A proxy user is a user that has been authorized to act for another user. Dynamic repository variables are useful for defining the content of logical table sources. 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. You can set execution precedence and deferred execution with multi-source session variables, similar to regular session variables. Asking for help, clarification, or responding to other answers. Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. Relation (Table) Tags: Data Partition Scripting on this page enhances content navigation, but does not change the content in any way. biServer is good where biserver is not good. It is also saved as the author field for catalog objects. StartDate)', 1, 3) = '200' or substr('valueof(NQ_SESSION. Spatial There are many times when it is very beneficial to pass the value of session variables (or report variables) into the SQL used to define a Select table in the physical layer. If you selected Dynamic, use the Initialization Block list to select an existing initialization block that will be used to refresh the value on a continuing basis. Graph This option is for session variable initialization blocks only. Using the Multi-Source Session Variable in a Data Filter. Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. To associate variables with initialization blocks: In the Variable Manager dialog, double-click the initialization block you want to edit. Note that the recommended practice is to use application roles rather than Catalog groups. In the [Repository|Session] Variable Initialization Block Data Source dialog, click Test. Cube See "Syntax and Usage Notes for SELECT_PHYSICAL" for more information. An initialization block contains the SQL statement that will be executed to initialize or refresh the variables associated with that block. You can now use the multi-source session variable MVCOUNTRY in a logical query. Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. Used to enable or disable Oracle BI Server subrequest cache hits and seeding. Data Partition You can edit Repository initialization blocks, or Session initialization blocks. Example message: "One of the successors for init block 'A_blk' does not have "Allow deferred execution" flag set. In the [Repository|Session] Variable Initialization Block Variable Target dialog, perform one of the following steps: Associate variables with the initialization block by doing one of the following: Click New, and in the Variable dialog, create a new variable. To remove a variable from association with this block, select the variable and click Remove. This section contains the following topics: System session variables are used by the Oracle BI Server and Oracle BI PresentationServices use for specific purposes. You can also use this variable in a SQL statement. Used to enable or disable Oracle BI Server result cache hits. Click here to get started. Selector ':PASSWORD' (note the colon and the single quotes) is the password the user enters. If there are fewer variables than columns, extra column values are ignored. 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. Init block 'B_blk' does not have "Allowed deferred execution" flag set. Each instance of a session variable could be initialized to a different value. When you check in the initialization block, the value of the dynamic variables is reset to the values shown in the Default initializer. Unlike dynamic repository variables, session variables are not updated at scheduled time intervals. Testing The syntax is: WHERE COMPANYID=ValueOf (NQ_SESSION.RETAILERID) The second case is where a session variable needs to be evaluated as a string. See "Testing Initialization Blocks" for more information. Otherwise, the default initialization SQL for the database type is used. Oracle BI, Each query can refresh several variables: one variable for each column in the query. If you selected Database for your data source type, perform one of the following steps: Select Default initialization string or Use database specific SQL, and then perform the following steps: Click Browse next to the Connection Pool field to select the connection pool associated with the database where the target information is located. The obiee logical sql request doesn't contain any filter : The logical request doesn't contain any filter : But the final query, send in the database, contains one. Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user. Http Privacy Policy See "Assigning a Name and Schedule to Initialization Blocks" for more information. The table contains three columns: USERID, containing values that represent the unique identifiers of the users, NAME, containing values that represent session variable names, VALUE, containing values that represent session variable values. For example, here are dates as set by the default values in the prompt. Infra As Code, Web COLUMN1 is having values VARIABLE1 , VARIABLE2 etc . Click Edit Data Source next to the Connection Pool field. The order of the columns in the SQL statement and the order of the variables associated with the initialization block determine which columns are assigned to each variable. There are a plethora of ways that dates can get formatted depending on which application is being used to select the dates. DataBase The Dynamic Name tab is not active unless at least one session variable is defined. If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? Example 19-3 A SQL Statement Joining Tables From Multiple Data Sources - When Using the 'OBI EE Server' Setting. Holds the value the user enters as his or her logon name. Example message: "The execution of init block 'A_blk' cannot be deferred as it is using row-wise initialization.". Variables should be used as arguments of the function VALUEOF(). 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. Operating System If you initialize a variable using a character string, enclose the string in single quotes ( ' ). 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. For information about using session variables when setting up security, see Managing Session Variables in Security Guide for Oracle Business Intelligence Enterprise Edition. 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. The call for a session variable is: VALUEOF("NQ_SESSION.Variable Name") See "Creating Repository Variables" or "Creating Session Variables" for information about creating variables. 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. A proxy user is a user that has been authorized to act for another user. The variables receive their values from the initialization string that you type in the Initialization Block dialog. Automata, Data Type In the Application Role dialog, click Permissions. Data (State) This variable is typically populated from the LDAP profile of the user. Number This section explains how to create repository variables. 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. How can I explain to my manager that a project he wishes to undertake cannot be performed by the team? For information about using session variables when setting up security, see "Managing Session Variables" in Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition. The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. OBIEE - How to set and use a server variable (system/repository) of type date ? Privacy Policy 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. The value of LOGLEVEL (a number between 0 and 5) determines the logging level that the Oracle BI Server uses for user queries. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. In the following example, the session variable RETAILERID has been assigned a numeric value. 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). Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. The names of system session variables are reserved and cannot be used for other types of variables. Distance This is another system variable whose presence is always assumed when the USER system session variable is used. The other two can not be addressed it seems, I have tried variations: The same goes for default selection type 'variable expression': the expected result is achieved when using @{biServer.variables['NQ_SESSION.STORENBR']}, yet no such luck using: @{biServer.variables['NQ_SESSION.SV_STORE_NBR']}, @{biServer.variables['NQ_SESSION. The multi-source session variable will fail only if all of the component initialization blocks return null values. By default, when you open the Initialization Block dialog for editing in online mode, the initialization block object is automatically checked out. This variable has a value of Yes. Because of this, if your repository has been upgraded from a previous release, you may see warnings in the Consistency Checker similar to the following: If you see warnings similar to this, update the relevant static repository variables so that the default initializers have constant values. Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'A' which is security sensitive.". OBIEE offer several variables which can be set : variables from the OBIEE Server known as session and repository variables. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. To create a new initialization block, click New. It's why you can't see in the session manager a new value for the session. The next step is to select the data source and connection pool. The value is case-insensitive. If you use a SQL tool, be sure to use the same DSN or one set up identically to the DSN in the specified connection pool. 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. It is recommended that you create a dedicated connection pool for initialization blocks where you select Database as the data source type. , however, the default initialization SQL for the user then select variables about using session,.
