You do this by assigning a value to the MESSAGE_LEVEL example: declare old_message_level number; begin :old_message_level := :system.message_level; :system.message_level := 20; -- suppresses most errors commit; -- action you want to do without messages or errors :system.message_level := old_message_level; end; If you hold any errors occurring in a variable or in a table you then show your own message after this code by checking your variable if an error has occurred. share|improve this answer answered Mar 5 '14 at 21:

What is an Error Trigger? Oracle offers the possibility to catch Oracle error messages. Some error messages normally only occur during SQLinjetion attempt. The trigger will intercept and report all these attempts.

Unlike a stored procedure, you can enable and disable a trigger, but you cannot explicitly invoke it. While a trigger is enabled, the database automatically invokes it—that is, the trigger fires—whenever its triggering event occurs. While a trigger is disabled, it does not fire. You create a trigger with the CREATE TRIGGER statement. You specify the triggering event in terms of triggering statements and the item on which they act. The trigger is said to be created on or defined on the item, which is either a table, a view, a schema, or the database. You also specify the timing point, which determines whether the trigger fires before or after the triggering statement runs and whether it fires for each row that the triggering statement affects. By default, a trigger is created in the enabled state. For more information about the CREATE TRIGGER statement, see "CREATE TRIGGER Statement". If the trigger is created on a table or view, then the triggering event is composed of DML statements, and the trigger is called a DML trigger. For more information, see "DML Triggers". If the trigger is created on a schema or the database, then the triggering event is composed of either DDL or database operation statements, and the trigger is called a system trigger. For more information, see "System Triggers". A conditional trigger has a WHEN clause that specifies a SQL condition that the database evaluates for each row that the triggering statement affects.
