Re: Some SQL Help Please

Hi Charlie;

You'll have to use the old fashioned outer join syntax.

This consists of adding the characters "(+)" onto the column(s) in your WHERE clause which refer to the 'optional' tables. By 'optional' I mean the tables that might or might not have matching rows.

This would change your WHERE clause from:

>
> WHERE A.key = B.key AND C.key = B.key AND D.key = C.key
> AND E.key = D.key AND F.KEY = E.key AND H.key = E.key
> AND G.key = H.key AND I.key = H.key;
>

to:
>
> WHERE A.key = B.key AND C.key = B.key AND D.key = C.key
> AND E.key = D.key AND F.KEY = E.key AND H.key = E.key
> AND G.key(+) = H.key AND I.key(+) = H.key;

Cheers, have fun tuning it!
