Use the VALUEOF function to reference the value of a repository variable. Repository variables are defined using the Administration Tool. You can use the VALUEOF function both in Expression Builder in the Administration Tool, and when you edit the SQL statements for an analysis from the Advanced tab of the Analysis editor in Answers.


Variables should be used as arguments of the VALUEOF function. Refer to static repository variables by name. Note that variable names are case sensitive. For example, to use the value of a static repository variables namedprime_begin and prime_end:

CASE WHEN "Hour" >= VALUEOF("prime_begin")AND "Hour" < VALUEOF("prime_end") THEN 'Prime Time' WHEN ... ELSE...END

You must refer to a dynamic repository variable by its fully qualified name. If you are using a dynamic repository variable, the names of the initialization block and the repository variable must be enclosed in double quotes ( " ), separated by a period, and contained within parentheses. For example, to use the value of a dynamic repository variable named REGION contained in an initialization block named Region Security, use the following syntax:

SalesSubjectArea.Customer.Region = VALUEOF("Region Security"."REGION")

The names of session variables must be preceded by NQ_SESSION, separated by a period, and contained within parentheses, including the NQ_SESSION portion. If the variable name contains a space, enclose the name in double quotes ( " ). For example, to use the value of a session variable named REGION, use the following syntax in Expression Builder or a filter:

"SalesSubjectArea"."Customer"."Region" = VALUEOF(NQ_SESSION.REGION)

Although using initialization block names with session variables (just as with other repository variables) may work, you should use NQ_SESSION. NQ_SESSION acts like a wildcard that matches all initialization block names. This lets you change the structure of the initialization blocks in a localized manner without impacting requests.
