OBIEE - Where can I use a BI Server variable (session/repository) ?

Bi Server Architecture With Client


When you have create a server variable, you have to reference it.

You can use them :

For the syntax, add NQ_SESSION if the variable is a session variable and see the relevant section for the function call.

In BI Server

You can modify the value of the session variable with a dashboard prompt. 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) ?


For a session variable:


For a repository variable:

VALUEOF("Variable Name")

Repository Objects

You cannot use variables to represent columns or other repository objects.

Connection Pool

OBIEE - Connection Pool: The picture below show a repository variable call but you can use in the same way the session variable syntax.

Obiee Session Variable In Connection Pool

You can find an example of a dynamic essbase connection pool in this post of christian berg:

Opaque View / Select Statement

In the bookshel Version, it's written that Only repository variables can be used in the definition. An error will generate if a session variable is used in the opaque view.

Obiee Physical Table Select Session Variable

With the version, a warning is generated:

WARNINGS: GLOBAL: The repository variable, 
NQ_SESSION.MYYEAR, has no value definition.

But BI Server process it without problem.

order by c1

in the Name of a Catalog or Schema

You can use a variable to specify the names of catalog and schema objects. For example, you have data for multiple clients and you structured the database so that data for each client was in a separate catalog. You would initialize a session variable named Client, for example, that could be used to set the name for the catalog object dynamically when a user signs on to the Oracle BI Server.

The Dynamic Name tab is not active unless at least one session variable is defined.

In Delivers

@{NQ_SESSION.Variable Name}

Other places

You can call a server variable by using this syntax :

  • The S of Server must be in uppercase. biServer is good where biserver is not good.
  • variables is plural. variables is good where variable is bad
  • Don't forget the quotes which enclose the Variable Name.
