Hi ,
I have few doubts reagrding set operators.
When i trying to run the following query ... its resulting in ORA-00928: missing SELECT keyword . i searched for the in google....its explaining about views and other stuff which is going above my head.
SELECT EMPNO FROM EMPCOMP WHERE ROWNUM < 10
INTERSECT ALL
SELECT EMPNO FROM ALLEMPS WHERE ROWNUM < 10
Simialrly i am getting errors ORA-00933 while running such queries with Except and except all.
i dont have access to create tables, so whatever table are present, i am using the same to understand set operators ..alos imp : when i ran the same queries using union, union all, interest , its working as intented.
Can anyone help.
thanks,
Meenal.
