Remarks

This option allows you to control the behavior of debugging messages in stored procedures and triggers that contain a MESSAGE statement with the DEBUG ONLY clause specified. By default, this option is set to Off and debugging messages do not appear when the MESSAGE statement is executed. By setting debug_messages to On, you can enable the debugging messages in all stored procedures and triggers.

Note DEBUG ONLY messages are inexpensive when the debug_messages option is set to Off, so these statements can usually be left in stored procedures on a production system. However, use them sparingly in locations where they would be executed frequently; otherwise, they can result in a small performance penalty.
