Re: Dimension table load - PLSQL question

Not in my test - I tried to omitt "matched" and it won't do. SQL> l
1 MERGE INTO bonuses D
2 USING (SELECT employee_id, salary, department_id FROM employees 3 WHERE department_id = 80) S
4 ON (D.employee_id = S.employee_id)
5 WHEN NOT MATCHED THEN INSERT (D.employee_id, D.bonus) 6* VALUES (S.employee_id, S.salary*0.1)
SQL> /
VALUES (S.employee_id, S.salary*0.1)
*
ERROR at line 6:
ORA-00905: missing keyword
