Subj:   Re: Update with left outer join
 
From:   Victor Sokovin

  You are trying to do a join on a column where it is Null. This will never work. Perhaps you meant "is not Null"?  


Randy, may I suggest you run the following two statements?

     sel *
     from (select 1 A ) D1 left outer join (select 1 A ) D2 on D1.A = D2.A
     where D2.A is null

     sel *
     from (select 1 A ) D1 left outer join (select 2 A ) D2 on D1.A = D2.A
     where D2.A is null

Have you changed your opinion?

Good.


Regards,

Victor
