[AccessD] Query Question

Nope, a subquery will only work returning one record for one
field...unless it's in the WHERE statement, where you can use 'IN' if
you want.

You'd have a problem reversing this by having the result fields show up
in the main query, because then it will only run the number of records
in LKUP, not the number in Table1.

Works like a dream Drew, you're a star as ever. Is there any way of
streamlining it to return more than 1 value from the subquery? Something
like

SELECT T1.LookupValue, (SELECT Result1, Result2 FROM LKUP WHERE
RangeStart<=T1.LookupValue AND RangeEnd>=T1.LookupValue) 
FROM Table1 as T1

Only I know that doesn't work cos I've tried it. Says something about
the
EXISTS keyword, and I don't know about that.
