1. Are you trying to show a LOV at run time? If so, you can create a LOV directly in the EUL via Disco Admin which will present a list of the items a user can choose from at run time (and not have to worry about a sub-query).
2. If it's an actual sub-query you need, then first of all, Disco v4 (maybe it was v9, but that was an ugly child anyway) is the last version that supported 'pseudo' sub-queries.
3. It's been written up in the forum many times about how to pass run time parameters to a folder in the EUL. There's one method that's popular for actually passing the parm to the folder.
4. Another method is to create a worksheet that only calls a function, to kick off a PL/SQL routine that builds a table using your parameter and then have the main worksheet call that new table.
So, if it's a LOV you want - that's a whole lot easier.
