I am trying to create a sub select in access 2002 to work in a form.  This is the code I am currently using, but access keeps telling me the sub select is invalid.

SELECT TblMediaExport.ord_confirm_date
FROM ([SELECT Table_and_Query_Lookup.TblMediaExport FROM Table_and_Query_Lookup WHERE Active = True] AS TblMediaExport)
WHERE ([TblMediaExport].[ord_id])>0;

SELECT TblMediaExport.ord_confirm_date, ([SELECT Table_and_Query_Lookup.TblMediaExport FROM Table_and_Query_Lookup WHERE Active = True]) AS TblMediaExport
FROM TblMediaExport
WHERE ([TblMediaExport].[ord_id])>0;

That subselect has no field outputs unless tblMediaExport is a field name, which still leaves that it is not the field used in the main select...

There is bracketing in the subselect that I'm not sure belongs there also.

You cannot reference anything from a sub if it's not defined (ord_id, ord_confirm_date).

Why do you want to run a sub on this ? It's simple enough, - you only have the table/query Table_and_Query_Lookup as input ? To me it looks like:

SELECT ord_confirm_date
FROM Table_and_Query_Lookup
WHERE ((ord_id>0) AND  (Active = True));

This is the logic of what I am trying to do,

1.)this query will return a table name;

SELECT Table_and_Query_Lookup.TblMediaExport FROM Table_and_Query_Lookup WHERE Active = True

2.)this query has the above query as a subselect within, I need to use that value returned by the subselect in the main select to reference a field within the subselects returned table name.

This is difficult to explain, further explanation may be necessary!
Thanks for your help though.

You are going to need to write the sql for the main query out in VBA before running it.  You can not force a field value directly into a query syntax in this manner.


  dim ssql as string
  dim stablename as string
  stablename = dlookup("tblMediaExport","Table_and_Query_Lookup","([Active] = true)")
  ssql = "SELECT ord_confirm_date "
  ssql = ssql & "FROM [" & stablename & "] " 
  ssql = ssql & "WHERE (ord_id>0);


then assign the ssql variable VALUE to a recordsouce or rowsource property somewhere.

OK,

This is farfetched, but if you're hooked on SQL then try this (no guarantees;-):

SELECT DLookUp("ord_confirm_date",SubXX.tblXX,"[" & SubXX.TblXX & "].[ord_id])>0") AS ReturnValue
FROM (SELECT Table_and_Query_Lookup.TblMediaExport AS tblXX FROM Table_and_Query_Lookup WHERE Active = True) AS SubXX;
