Re: Problem with LEF OUTER JOIN
Did you actually try this statement with the data you provided?
select * from tblCat C LEFT OUTER JOIN tblCatDet D ON C.ID=D.CatID WHERE D.color='2'
If I am not wrong, this will return emtpy set in the result, since there is no rows satisfy the condition D.color='2'
Maybe you want to try
select * from tblCat C LEFT OUTER JOIN tblCatDet D ON C.ID=D.CatID WHERE D.color='clr'
and compare it with
select * from tblCat C LEFT OUTER JOIN tblCatDet D ON C.ID=D.CatID WHERE D.color='clr' OR D.color IS NULL
