This article is to share with you about how MySQL uses event to automatically divide tables. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The new unit needs a sub-table to deal with a large log table.

First, turn on the event function.

SET GLOBAL event_scheduler = 1

Then automatically create a new table based on time and change the view to the query of the new table.

-- simulated log table

Create table T1 (id int,log varchar (30))

-- simulated view

Create view v_log as select * from T1

Delimiter $$

CREATE EVENT test_event

ON SCHEDULE

EVERY 1 second

STARTS str_to_date ('2014-04-14 20, 14, 20, 12, 10, 12, 14, 14, 20, 10, 12, 14, 14, 20, 10, 14, 14, 20, 14, 14, 04, 14, 20, 14, 04, 14, 20, 14, 04, 14, 20, 14, 14, 04, 14, 20, 14, 14, 04, 14, 20, 14, 20, 14, 04, 14, 20, 14, 20, 14, 04, 14, 20, 14, 20, 14, 04, 14, 20, 14, 20, 14, 20, 14, 04, 14, 20, 14, 04, 14, 20, 14, 04, 14, 20, 14, 04, 14, 20, 14, 04, 14, 20, 14, 04, 14, 20, 14, 04, 14, 20, 14, 04, 14, 20, 14,
