MySQL: return updated rows

Question

I am trying to combine these two queries in twisted python:

SELECT * FROM table WHERE group_id = 1013 and time > 100;

and:

UPDATE table SET time = 0 WHERE group_id = 1013 and time > 100

into a single query. Is it possible to do so?

I tried putting the SELECT in a sub query, but I don't think the whole query returns me what I want.

Is there a way to do this? (even better, without a sub query) Or do I just have to stick with two queries?

Thank You,

Quan

Apparently mysql does have something that might be of use, especially if you are only updating one row.

This example is from: http://lists.mysql.com/mysql/219882

UPDATE mytable SET
mycolumn = @mycolumn := mycolumn + 1
WHERE mykey = 'dante';

SELECT @mycolumn;

I've never tried this though, but do let me know how you get on.
