How to update a trigger in oracle?

To update a trigger in Oracle, follow these steps:

1. Connect to the Oracle database using a client tool such as SQL*Plus or SQL Developer.
2. Find the trigger you want to update by querying the user_triggers or all_triggers data dictionary view. For example, you can use the following SQL query to find a trigger named EMP_UPDATE_TRIGGER in the SCOTT schema: SELECT trigger_name, trigger_type, triggering_event, table_name FROM user_triggers WHERE trigger_name = 'EMP_UPDATE_TRIGGER';
3. Once you have identified the trigger you want to update, you can modify its definition using the ALTER TRIGGER command. For example, if you want to update the trigger code for the EMP_UPDATE_TRIGGER trigger in the SCOTT schema, you can use the following SQL statement: ALTER TRIGGER SCOTT.EMP_UPDATE_TRIGGER [new trigger code];
4. Make sure to replace [new trigger code] with the updated trigger code that you want to set for the trigger.
5. Once you have updated the trigger code, you can save the changes and test the trigger to make sure it works as expected.
6. Remember to commit the changes using the COMMIT statement to make them permanent in the database.
7. Verify that the trigger has been successfully updated by querying the user_triggers or all_triggers data dictionary view again.

By following these steps, you can easily update a trigger in Oracle.
