How to get the last access (and/or write) time of a MySQL database?

To get the last access time, try the following syntax -

SELECT update_time
FROM INFORMATION_SCHEMA.TABLES
WHERE table_schema = 'yourDatabaseName'
AND table_name = 'yourTableName'

The above syntax gives the last access information about the MyISAM engine type.

Here, our database is "business" and we will use a table named "twoprimarykeytabledemo".

To get the last access time of a MySQL database, use the following query.

Case 1 - The query is as follows-

mysql> SELECT update_time
   -> FROM INFORMATION_SCHEMA.TABLES
   -> WHERE table_schema = 'business'
   -> AND table_name = 'twoprimarykeytabledemo';

The output is as follows-

+---------------------+
| UPDATE_TIME         |
+---------------------+
| 2018-11-21 16:51:50 |
+---------------------+
1 row in set (0.24 sec)

Case 2 -

mysql> SELECT update_time
   -> FROM INFORMATION_SCHEMA.TABLES
   -> WHERE table_schema = 'business'
   -> AND table_name = 'currenttimezone';

The output is as follows -

+---------------------+
| UPDATE_TIME         |
+---------------------+
| 2018-10-29 17:20:18 |
+---------------------+
1 row in set (0.20 sec)

Case 3 - If your table engine type is InnoDB, then you will get NULL.

The query is as follows -

mysql> SELECT update_time
   -> FROM INFORMATION_SCHEMA.TABLES
   -> WHERE table_schema = 'business'
   -> AND table_name = 'zerofilldemo';

The following is the output -

+-------------+
| UPDATE_TIME |
+-------------+
| NULL        |
+-------------+
1 row in set (0.09 sec)
