1: EMPLOYEE_ID := DBMS_RANDOM.STRING('X',6); ---- its generates unique EMPLOYEE_ID six char long

2: Then check whether newly generated id is already in DB. Create a cursor which select and return ids and the match both vales. If both are equal then go back to step 1

3: you unique value has created.

I hope this will help you.
