In my MySQL database I have some triggers ON DELETE and ON INSERT. Sometimes I need to disable some triggers, and I have to DROP e.g.

DROP TRIGGER IF EXISTS hostgroup_before_insert //

and reinstall. Is there any shortcut to SET triggers hostgroup_before_insert = 0 like we have for foreign keys:

mysql> SELECT version();
+-------------------------+
| version()               |
+-------------------------+
| 5.1.61-0ubuntu0.10.10.1 |
+-------------------------+
1 row in set (0.00 sec)

EDIT Answer There is no built-in server system variable TRIGGER_CHECKS in MySQL.
A simple workaround is to instead use a user-defined session variable. 

#FALSE value overrides trigger type settings
SET @TRIGGER_CHECKS = [TRUE|FALSE]; 

SET @TRIGGER_BEFORE_INSERT_CHECKS = [TRUE|FALSE];
SET @TRIGGER_AFTER_INSERT_CHECKS = [TRUE|FALSE];

DELIMITER $$
DROP TRIGGER IF EXISTS `yearCheck_beforeInsert` $$
CREATE DEFINER=`root`@`localhost` TRIGGER `yearCheck_beforeInsert`
BEFORE INSERT ON `movies` FOR EACH ROW 

#Patch starts here
thisTrigger: BEGIN
  IF ((@TRIGGER_CHECKS = FALSE)
      OR (@TRIGGER_BEFORE_INSERT_CHECKS = FALSE))
    AND (USER() = 'root@localhost')

This TRICK is Explained here.
