Hello,
Can someone help me out with this.
I have two tables, CLIENT AND EMPLOYEE
ClIENT EMPLOYEE
-------- -----------
CREATED_BY EMPLOYEE_NO
MODIFIED_BY EMPLOYEE_NAME
where if created_by = 100 then employee_no=100 and employee_name is "Mr. XYZ" meaning client.created_by=employee.employee_no
How can I in my *select* statement retreive both the created_by field and modified_by fields not with the numbers but with the names (employee_name)
Your help on this would be highly appreciated.

select c.*, e1.employee_name created_by_name, e2.employee_name modified_by_name
from client c, employee e1, employee e2
where e1.employee_no = c.created_by
and e2.employee_no (+)= c.modified_by;
I specified the join on modified_by as an outer join (+) in case this column is NULL until modified. If it initially has the same value as created_by, then the outer join is not required.
