Row versioning in MySQL

I would like to include an integer version field in my table, auto-incrementing on each update made to a row. Is it possible to do this in MySQL?

Please note that I'm not talking about a TIMESTAMP, which is not reliable as two concurrent updates might happen during the same second.

Solution

  • The only way (I can think of) to do this is a (before-update) trigger that automatically increments the column value.
