How can I tell when a MySQL table was last updated?

Question

In the footer of my page, I would like to add something like \"last updated the xx/xx/200x\" with this date being the last time a certain mySQL table has been updated.

Answer 1

The simplest thing would be to check the timestamp of the table files on the disk. For example, You can check under your data directory

cd /var/lib/mysql/
ls -lhtr *.ibd

This should give you the list of all tables with the table when it was last modified the oldest time, first.
