Oracle – PL-SQL – ORA-04091: table name is mutating, trigger/function may not see it

Error: ORA-04091: table name is mutating, trigger/function may not see it

Cause: Mutating trigger error occurs when a trigger references the table that owns the trigger. So the result is we receive the above error message.

Solution:

We cannot refer the table in the trigger that owns the trigger. If you face the similar condition or scenario then don’t use the trigger for that purpose. Use the alternative approach to handle this situation you can refer the Mutating Table Exceptions or Autonomous Transactions
