I have the below code :
INSERT INTO Table_Delete (name)
SELECT su_name
FROM Student_Data
where class = '12'
MINUS
SELECT name
FROM Students
WHERE roll_num in (select roll_num from RollNumber
where class = '12');
COMMIT;
exit
I need to update this code to check if content of Table_Delete = Table_2 then empty Table_delete. I am not able to do this via If exists command.
Can anyone please help me on this ? I am using Oracle 9i.
