Is there any possibilities to drop multiple events using single query ? I know, we can get list of events using show events and drop single event with there name.
In mysql 5.7 or lowest version it is possible but i am using mysql 8.0.
I suggest using MySQL Shell - for a one off, you can use (using Python mode):
mysqlsh> \py
mysql-py> i_s = session.get_schema("information_schema")
mysql-py> events = i_s.EVENTS \
-> .select("sys.quote_identifier(EVENT_SCHEMA) AS EventSchema", "sys.quote_identifier(EVENT_NAME) AS EventName") \
-> .where("EVENT_SCHEMA = 'db1'").execute().fetch_all();
mysql-py> events
[
[
"`db1`",
"`event1`"
],
[
"`db1`",
"`event2`"
],
[
"`db1`",
"`event``3`"
]
]
mysql-py> sql_fmt = "DROP EVENT {0}.{1}"
mysql-py> for event in events:
-> print(sql_fmt.format(*event))
-> session.sql(sql_fmt.format(*event)).execute()
->
DROP EVENT `db1`.`event1`
DROP EVENT `db1`.`event2`
DROP EVENT `db1`.`event``3`
Query OK, 0 rows affected (0.0038 sec)
