Hello Ben, I had the same question yesterday (but with SQLite) and there are at least 2 solutions. The first was already mentioned: UPDATE table SET value = value + 1 WHERE foo = bar; The second solution which also works is: UPDATE table SET value = (SELECT value FROM table WHERE foo = bar) + 1 WHERE foo = bar; I hope it helps.

I hope this isn't a bone-head question - Is there a MySQL query that will increment/decrement the value in an integer column with a single query - in other words, I don't have to run a SELECT query to get the value, add/subtract to/from the value, and then run an UPDATE query to store the new value? Thanks in advance. Ben
