Is there any difference in the 2 SQLs.
The problem is that in the 1st SQL, I got only 2 Values for Service and the whole action happens on just 2 AMPS and it becomes skewed.
I then changed it to be a SubQuery. Are they both the same.
SELECT ast.id, max(wm.stat) AS codes
FROM ast LEFT OUTER JOIN wm
ON
ast.id = '0000'
AND ast.service = wm.service ;
SELECT ast.id, max(wm.stat) AS codes
FROM ast LEFT OUTER JOIN wm
ON
ast.id = '0000'
AND ast.service_group in (sel service from wm) ;
Thanks a Million.
