By creating an Event, tasks such as data backup, data cleaning, and statistics can be regularly executed in the database.<\/p>\n<p>Using Events can eliminate the need for manual execution of these tasks, improving the performance and reliability of the database. Events can be scheduled to run at specific times or at regular intervals.<\/p>\n<p>In order to create an Event, you need to use the CREATE EVENT statement and specify the Event&#8217;s name, execution time, execution statement, and other information. For example:<\/p>\n<pre class=\"post-pre\"><code><span class=\"hljs-keyword\">CREATE<\/span> EVENT myevent\r\n    <span class=\"hljs-keyword\">ON<\/span> SCHEDULE <span class=\"hljs-keyword\">AT<\/span> <span class=\"hljs-built_in\">CURRENT_TIMESTAMP<\/span> <span class=\"hljs-operator\">+<\/span> <span class=\"hljs-type\">INTERVAL<\/span> <span class=\"hljs-number\">1<\/span> <span class=\"hljs-keyword\">HOUR<\/span>\r\n    DO\r\n      <span class=\"hljs-keyword\">UPDATE<\/span> mytable <span class=\"hljs-keyword\">SET<\/span> mycol <span class=\"hljs-operator\">=<\/span> mycol <span class=\"hljs-operator\">+<\/span> <span class=\"hljs-number\">1<\/span>;\r\n<\/code><\/pre>\n<p>The above example creates an Event named myevent that will execute an UPDATE statement every hour to update data in the mytable table.<\/p>\n<p>To enable Event, the event scheduler needs to be enabled in the database. You can use the following statement to enable the event scheduler:<\/p>\n<pre class=\"post-pre\"><code><span class=\"hljs-keyword\">SET<\/span> <span class=\"hljs-keyword\">GLOBAL<\/span> event_scheduler <span class=\"hljs-operator\">=<\/span> <span class=\"hljs-keyword\">ON<\/span>;\r\n<\/code><\/pre>\n<p>Using Events can easily manage regularly scheduled tasks in the database, improving the efficiency of database automation operations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In MySQL, an Event is a mechanism used for scheduling operations to be performed at specific times.
