Prahlad,

Without considering the validity of your logic, here is what you can do.

     update tab1 a
     >From
     (select aa.col1
     >From tab1 aa
     Left outer join tab2 bb
     on a.col1 = b.col1
     where b.col1 is null) b
     set col1 = 999
     Where a.col1 = b.col1
     ;

Hope this helps.
