SQL in reports filter expression

Question

Hi All,
I want to filter the report using the 'in' operator and specify a SQL as the expression. I want apex to be use the result of the query as the list of values for the 'in' operator. Is this supported?
for example can I specify the filter as 'user_name in (select name from user_name_tab where group_id = 10)'
Thanks

Hi Micek,
Thanks for your quick reaction.
Yes you are right the ChosenValues will be replaced by presentation-variables in the final dashboard,
I just am testing it with constant values in the Answers module.
The problem seems to be that it is not allowed to use a sub-query in the filter expression.
The Answers web application says there is a syntax problem near <select>, while I expect the SQL to be valid.
I guess not all regular SQL is allowed in filter expressions.
And since the report does not try to fetch data, no log of a generated, real SQL is written to the logfile.
I need some alternative for the subquery, but one that is allowed in the filter expression.
The problem is based on the fact that the user chooses a different value then the one that is filtered on.
The timePeriods represent just one startDate, but I cannot use timePeriod itself to filter on.
Because I need a between value, wich does not make sense for a timePeriod element
such as '01-08' or 'JAN-08'.
Several timePeriod notations are used, so using SubString and || to calculate a numeric value from the timePeriod varchar2 is not a good option.
The error says:      
Error getting drill information: SELECT "....
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 27002] Near <SELECT>: Syntax error [nQSError: 26012] . (HY000)
Any input is welcome
kind regards
