Hello

How to enforce referential integrity between 2 tables located in separate Data-
bases ? Example :

   table EMP is on DB A
   table DEPT is on DB B

When I insert or update an employee the DEPTNO-Check against the DEPT-Table must be executed. How can I reach that ? Ref.-Int. doesn't work over DB-Links. Is the only solution a procedure or a DB-Trigger ?

Thanks for ANY ADVICE.
