MySQL 이벤트의 메타데이터를 어떻게 얻나요?

이 작업은 INFORMATION_SCHEMA 데이터베이스를 사용하여 수행할 수 있습니다. 다음 명령문은 이벤트의 메타데이터를 제공합니다 -

mysql> SELECT * from INFORMATION_SCHEMA.EVENTS WHERE EVENT_NAME LIKE '%event%' A

ND EVENT_SCHEMA = 'query'\G
*************************** 1. row ***************************
      EVENT_CATALOG: def
