You should test this SQL using the Test button in the [Repository|Session] Variable Initialization Block Data Source dialog. The second case is where a session variable needs to be evaluated as a string. Each query can refresh several variables: one variable for each column in the query. COMPANYID is the name of a physical column. Cube See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. It is also saved as the author field for catalog objects. Ive done it this way. For example, suppose you have two sources for information about orders. Connect and share knowledge within a single location that is structured and easy to search. The Required for authentication option is dimmed, because this type of initialization block is executed after authentication. The names of system session variables are reserved and cannot be used for other types of variables. If you do not select a connection pool before typing the initialization string, you receive a message prompting you to select the connection pool. When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC). However, it will still work with other data sources because the SQL statement is processed by the Oracle BI Server. There are a plethora of ways that dates can get formatted depending on which application is being used to select the dates. See "About Using Initialization Blocks with Variables" for more information.

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. 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. If the database object has the Virtual Private Database option selected, the Oracle BI Server matches a list of security-sensitive variables to each prospective cache hit. Used to enable or disable Oracle BI Server result cache seeding. About Using Initialization Blocks with Variables, Associating Variables with Initialization Blocks, When Execution of Session Variable Initialization Blocks Cannot Be Deferred, Enabling and Disabling Initialization Blocks. Used to enable or disable Oracle BI Server result cache seeding. Contains the time zone of the user, typically populated from the LDAP profile of the user. Select Use OBI EE Server, and then perform the following steps: In the box, enter the SQL initialization string needed to populate the variables. It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. The new value is only valuable for the query. Dynamic repository variables are useful for defining the content of logical table sources. For static repository variables, the value you specify in the Default initializer window persists. The Required for authentication option is selected in the Session Variable Initialization Block dialog. For session variables, you can select the following options: Enable any user to set the value. 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. Security Click Edit Data Source next to the Connection Pool field. The syntax is: WHERE COMPANYID=ValueOf (NQ_SESSION.RETAILERID) The second case is where a session variable needs to be evaluated as a string. Status, to include it in a where clause of the content tab of a logical table source, to create a dashboard prompt to set up this session variable, and to test it on a little answer with only the year as column, click on the node : Session/Variables/Non System, and create a session variable MyYear with for instance this default initialization string for the oracle database, Set Variable : Request Variable and the value MyYear, Server Presentation Service Installed On Two Machines. This behavior ensures that you cannot use the same connection pool for initialization blocks that you use for queries. Create a session variable called MVCOUNTRY____SEBL, making sure to include four underscores between the variable name and the source name. Is there any way to do this? If you want the query for an initialization block to have database-specific SQL, you can select a database type for that query. 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. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. If the database object has the Virtual Private Database option selected, the Oracle BI Server matches a list of security-sensitive variables to each prospective cache hit. Data Visualization In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. Create an Agent with OBIEE Analytics Agents enable you to automate your business processes. Discrete In the View Data from Table dialog, type the number of rows and the starting row for your query, and then click Query. If you are using a calendar thats different from the normal Gregorian calendar (i.e. Execution of session variable initialization blocks during session logon can be deferred until their associated session variables are actually accessed within the session. For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. The USER value always matches the PROXY variable, that is the act as value. This variable has a possible value of 0 or 1. Data Concurrency, Data Science Nominal Dimensional Modeling For information about using session variables when setting up security, see Managing Session Variables in Security Guide for Oracle Business Intelligence Enterprise Edition. File System The query returns data only if the user ID and password match values found in the specified table. In this case, the trusted internal process can connect regardless of whether the initialization block succeeds or fails. The Variable Manager appears. Time Data Warehouse The multi-source session variable will fail only if all of the component initialization blocks return null values. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. What are some tools or methods I can purchase to trace a water leak? 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. Therefore, when you associate variables with an initialization block, the value returned in the first column is assigned to the first variable in the list. OBIEE - Where can I use a BI Server variable (session/repository) ? In RPD, I created a new init block with session variable PRODUCT and row wise initialization is set. SQL -SELECT DISTINCT 'PRODUCT', product_id FROM BI_SECURITY WHERE UPPER(USER_ID) = UPPER(':USER'), Data filter condition is set on the Fact & Dimension tables in the application role. The query returns data only if the user ID and password match values found in the specified table. You could then set a security filter for all members of a group that would allow them to view only data pertinent to their region. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Presentation Services. The deferred execution of an initialization block also triggers the execution of all unexecuted predecessor initialization blocks. OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Does Cosmic Background radiation transmit heat? You use the same procedure to define nonsystem session variables as for system session variables. Each instance of a session variable could be initialized to a different value. Collection Instead, the Oracle BI Server creates new instances of those variables whenever a user begins a new session. Example message: "The execution of init block 'A_blk' cannot be deferred as it is using row-wise initialization.". Collection OAuth, Contact If Prime Time were one of those segments and corresponded to the hours between 5:00 PM and 10:00 PM, you could create a CASE statement like the following: where Hour is a logical column, perhaps mapped to a timestamp physical column using the date-and-time Hour(<
>) function. 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. The Oracle BI Server uses the cached results for subsequent sessions. You cannot use variables to represent columns or other repository objects. Html If you do not want this to occur, use the Undo Check Out option. Process If you select this option, the initialization block is disabled. You initialize dynamic repository variables in the same way as static variables, but the values are refreshed by data returned from queries. 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. See "Syntax and Usage Notes for SELECT_PHYSICAL" for more information. Graph a fiscal calendar) that you have stored in a Periods table, you can write the analogous SQL for that calendar. WHERE upper (SALESREP) = upper ('valueof (NQ_SESSION.USER)') The third case, dates, is the hardest. 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.

The presentation service can also send this error : Try to use the same letter case for the name of the variable (upper and lower). OBIEE 11g - The session variable, NQ_SESSION.VARIABLE, has no value definition user11173172 Feb 20 2015 edited Feb 27 2015 Hello, I am seeing a strange issue when using SESSION variable in OBIEE 11g RPD for data level security. Monitoring 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. Spatial Instead, the connection pool is blacklisted and subsequent initialization blocks for that connection pool are skipped. (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. How does the NLT translate in Romans 8:2? Linear Algebra You can now use the multi-source session variable MVCOUNTRY in a logical query. To remove a variable from association with this block, select the variable and click Remove. Contains the application roles to which the user belongs. 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. You would initialize a session variable named Client, for example, that could be Security 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? Enable any user to set the value. For repository variable initialization blocks, when you open a repository in online mode, the value shown in the Default initialization string field of the Initialization Block dialog is the current value of that variable as known to the Oracle BI Server. And when i try a system session variable VALUEOF(NQ_SESSION. Mathematics The call for a session variable is: VALUEOF("NQ_SESSION.Variable Name") Scripting on this page enhances content navigation, but does not change the content in any way. Dom If a semicolon must be included as part of a group name, precede the semicolon with a backslash character (\). Scripting on this page enhances content navigation, but does not change the content in any way. The values remain unchanged for the duration of the session. You should test the SQL statement outside of the Oracle BI Server, substituting valid values for the USER and PASSWORD variables and removing the NQS_PASSWORD_CLAUSE clause. In other words, users are denied access to Oracle Business Intelligence if the initialization block fails to execute. Discrete Note: The Allow deferred execution option is unavailable in some circumstances. The value of LOGLEVEL (a number between 0 and 5) determines the logging level that the Oracle BI Server uses for user queries. Data Structure Selecting the Use caching option directs the Oracle BI Server to store the results of the query in a main memory cache. Specifies the Catalog groups (Presentation Services groups) to which the user belongs, if any. In the Administration Tool, select Manage, then select Variables. For example, the following CASE statement is identical to the one explained in the preceding example, except that variables have been substituted for the constants: You cannot use variables to represent columns or other repository objects. To create a new initialization block, click New. Why is the error occurring only for User B? For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. You can overtype this string. 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. ':PASSWORD' (note the colon and single quotes) is the password the user enters. ", Example message: "The execution of init block 'A_blk' cannot be deferred as it does not have a connection pool.". 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). To add a Default Initializer value, type the value in the Default Initializer box, or click the Expression Builder button to use Expression Builder. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. 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. 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 you select Database as the data source type for an initialization block, the values returned by the database for the columns in your SQL statement are assigned to variables that you associate with the initialization block. Could anyone please advise? In previous releases, the Administration Tool did not limit the values of default initializers for static repository variables. If there are more variables than columns, the additional variables are not refreshed (they retain their original values, whatever they may be). When the user modifies the date range using the first calendar, the format of the first date changes. Data Partition Repository variables and system and nonsystem session variables are represented by a question mark icon. A proxy user is a user that has been authorized to act for another user. was shown. Order In the Variable Manager dialog, select Action > New > Session > Variable. Holds the Oracle BI Presentation Services user interface display language. One source contains recent orders and the other source contains historical data. The SQL statement you use to refresh the variable might be written for a specific database. If you select Database as the data source type: If you select Database as the data source type, and do not select the Use OBI EE Server option. Cause had logged in as admin and i got back the value (get back number: 2) as I expected In the start_level column of the business layer i used the following script as source: INDEXCOL( VALUEOF(NQ_SESSION . Data Persistence For example, suppose you want to create session variables using values contained in a table named RW_SESSION_VARS. 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). Create a dashboard prompt with the following characteristics : Select only the column Calendar.Calendar Year. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. (Session init blocks only) Select an option. You schedule these queries to be executed by the Oracle BI Server. When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC). 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.
