Subj:   Re: Subquery
From:   Cornelius Meade


I think this query problem is essentially in the same problem domain as the "query conundrum" example I posted to the list yesterday and I believe you will find that a derived table based solution could also be used for this, as well as for more complex problems of this type. However the example here does not seem to really need a subquery as I believe a simple join solution could be coded as follows. This seems overly simple (although I know we've all not seen the forest for the trees from time to time)...Is there something more to this problem that I am not seeing in your example?


select ta.a,
       tb.b c
  from ta,
 where ta.a = tb.a ;
