How can we start MySQL event scheduler?

Actually, MySQL event scheduler is a process that runs in the background and constantly looks for the events to execute. But before we create or schedule an event we just have to start the scheduler. It can start with the help of the following statement −

mysql> SET GLOBAL event_scheduler = ON;
Query OK, 0 rows affected (0.07 sec)

Now with the help of the following statement, we can check its status in MySQL process list −

mysql> SHOW PROCESSLIST\G
*************************** 1. row ***************************
     Id: 3
   User: root
   Host: localhost:49500
     db: query
Command: Query
   Time: 0
  State: starting
   Info: SHOW PROCESSLIST
*************************** 2. row ***************************
     Id: 4
   User: event_scheduler
   Host: localhost
     db: NULL
Command: Daemon
   Time: 11
  State: Waiting on empty queue
   Info: NULL
2 rows in set (0.06 sec)

It can be turn off with the help of the following statement −

mysql> SET GLOBAL event_scheduler = OFF;
Query OK, 0 rows affected (0.07 sec)
