One of the sorely wanted features missing in MySQL is the ability to disable/enable triggers on the fly. By comparison, disabling/enabling Foreign Key constraints can be simply done by setting a server system variable:
SET FOREIGN_KEY_CHECKS = [TRUE|FALSE];
Now as of version 5.6, there is no built-in server system variable TRIGGER_CHECKS in MySQL. A simple workaround is to instead use a user-defined session variable. The setting for trigger checks stored into the session variable allows the setting to be seen by all statements, including all stored procedures and functions, as long as the user is connected, which for this workaround is in effect similar to using a server system variable.
