Controls whether or not MESSAGE statements that include a DEBUG ONLY clause are executed.
ON, OFF
OFF
This option allows you to control the behavior of debugging messages in stored procedures 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.
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, they should be used
sparingly in locations where they would be executed frequently;
otherwise, they may result in a small performance penalty.
