How do you get the last access (and/or write) time of a MySQL database?
문제
How do you find out the last time a MySQL database was read or written to?
Can you even do that check per table?
해결책
SELECT UPDATE_TIME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = 'dbname'
AND TABLE_NAME = 'tabname'
다른 팁
If your database has bin logs switched on, you can get the last update time using mysqlbinlog.
If your database has query logging enabled, you can get the last query time (either updates or selects) by tailing the query log.
check out command SHOW TABLE STATUS
;
example: SHOW TABLE STATUS WHERE name="table_name_here", you need value from column Update_time
