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

Cache the query in a global variable when it is not available.

Create a webpage to force the cache to be reloaded when you update it.

Add a call to the reloading page into your deployment scripts.
