Question

I am trying to set a particular value to the last row in a table, but I’m not sure how to do this with subqueries. I am getting the sid of the last row in the table by

SELECT sid ORDER BY timestamp DESC LIMIT 1

and I want to assign “bar” to the foo column of that sid.

This is what I have so far, but it does not work (#1235 – This version of MySQL doesn’t yet support ‘LIMIT & IN/ALL/ANY/SOME subquery’).

UPDATE table SET foo="bar" WHERE sid IN (SELECT sid ORDER BY timestamp DESC LIMIT 1)

Any ideas?

Thanks!

You don’t need a subquery at all. 🙂

UPDATE `table` SET `foo` = 'bar' ORDER BY `timestamp` DESC LIMIT 1;
