SELECT 'VALUEOF(NQ_SESSION.WEBLANGUAGE)' FROM DUAL I have set up a session variable initialization block to read in the variable names and values from my translated strings table with this SQL: select session_variable,translation from W_LOCALIZED_STRING_G where lang_id='VALUEOF(NQ_SESSION.LOCALE)' Linear Algebra Holds the value the user enters. When you use these variables for Oracle BI Server, preface their names with NQ_SESSION. Table 19-2 shows the table in this example. Note: The Allow deferred execution option is unavailable in some circumstances. Contains the time zone of the user, typically populated from the LDAP profile of the user. In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. Visit our Welcome Center, Answers/Dashboards (Presentation Services).
