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.
Greetings from Germany,
Sebastian

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
