Hi all,

I need to update 3 column in the same table based on different condition. Please give me a hint which query i use. Individual query of all update or handle in single query eg

Update GD
SET GD.TD =(select ABD.TD from ABD,GAC where ABD.SEQ=GAC.SEQ
And GAC.GI=GD.GI
AND ABD.TD > GD.TD AND GD.TD is null AND ABD.TD is not null)
,
GD.TT=(select ABD.TT from ABD,GAC where ABD.SEQ=GAC.SEQ
And GAC.GI=GD.GI
AND ABD.TT > GD.TT AND GD.TT is null AND ABD.TT is not null)
,
GD.TF==(select ABD.TF from ABD,GAC where ABD.SEQ=GAC.SEQ
And GAC.GI=GD.GI
AND ABD.TF > GD.TF AND GD.TF is null AND ABD.TF is not null)

Why isn't this one working for you, aside form the obvious duplicated-equal-sign syntax error?
