How to Show Events in MySQL: Syntax and Examples
To show events in MySQL, use the
SHOW EVENTS command. This lists all scheduled events in the current database. You can also filter events by database using SHOW EVENTS FROM database_name.Syntax
The basic syntax to display events in MySQL is:
SHOW EVENTS;- Lists all events in the current database.SHOW EVENTS FROM database_name;- Lists events from a specific database.
This command shows event names, schedules, status, and other details.
sql
SHOW EVENTS;
SHOW EVENTS FROM your_database_name;Example
This example shows how to list all events in the current database and what the output looks like.
sql

Common Pitfalls
Common mistakes when showing events include:
- Not selecting the correct database before running
SHOW EVENTS, which shows events only for the current database. - Expecting events to show when the event scheduler is off. Events exist but won't run if the scheduler is disabled.
- Using
SHOW EVENTSwithout proper privileges; you need theEVENTprivilege.
sql
/* Wrong: No database selected, no events shown */ SHOW EVENTS; /* Right: Select database first */ USE your_database_name; SHOW EVENTS;
