Using unlinked sql command and table in a subreport

Question

All,
Does CR allow using an unlinked sql command and a table in the same subreport?  I am passing the CurrentCEUserName from the main report to the sql command in the subreport (via linked parameter).  The sql command then executes a query to pass the parameter to the database (example: select myfunction('{?myparam}' from dual).  I need this to run before subreport's table query is executed. 
This all appears to work except that the parameter passed to the sql command isn't set when the command executes.  The value is always null when the sql command is executed.  If I add the parameter to the report output it shows the expected value. 
Also, if I have a subreport that just has a single sql command the parameter is set correctly prior to executing the command.
any help would be appreciated.
thanks!

If you are looking for Crystal to run the SQL Command, then the SQL it generates itself, I think the answer is no, it won't do that.  Crystal expects all of the data sources to be linked, I believe.  I'm not sure what you would expect to happen if they are not...  However, you can make your SQL Command something like (MS SQL; sorry, it's been too long since I've used Oracle...):
declare @result varchar(100);
set @result = ( select myfunction('{?myparam}') );
select * from table;
which would run the first select calling your function, basically throw away the result (or you can do with it as needed), then return the fields from your table.
