Update employees set(AGE, INCOME) =

 Case

when AGE = 19 and Income = 5000 then QUAL= 'HTC'

 WHEN AGE = 19 and Income = 4000 then QUAL = 'MI'

 else

 QUAL = 'HP'

/

Case

ERROR at line 2:

ORA-01767: UPDATE ... SET expression must be a subquery

Can anyone help me in resolving this query.

This really has nothing to do with SQL Developer (the subject of this forum). It is a much better fit in SQL & PL/SQL.

And just as a side comment, storing 'age' as data is a flawed design. The 'age' of everyone and every thing is increasing by the day, if not by the second. What is your plan to keep 'age' current? Better to store 'date of birth' and the calculate 'age' when needed at run-time.

The 'age' of everyone and every thing is increasing by the day, if not by the second.

Sometimes the age stops increasing.

Pour me one!

Of course, that's not actually the age, but the amount of time it was 'aged' in the barrel before bottling.
