Oracle Error Message
ORA-28132: The MERGE INTO syntax does not support the security policy.
Reason for the Error
The MERGE INTO syntax did not support a security policy on the destination table, because the policy’s statement_types did not include each of INSERT, UPDATE and DELETE.
Solution
If you do not have the privilege to modify the security policy, then instead of MERGE INTO, use the INSERT, UPDATE and DELETE DML statements on the table that has a security policy defined on it. If you have the privilege to modify the security policy, then redefine it in such a way that statement_types includes all of the DML statement types (INSERT, UPDATE and DELETE).
