[PHP] MySQL: Return Number of Matched Rows
Hey everyone, I have a question. If I do a mysql query that updates a column in a row to the same value, I get 0 rows affected. However, I also get 1 or more matched rows. Is there a way that I can return the number of matched rows, rather than the number of rows affected? I'm trying to get something done with as few SQL queries as possible. Thanks!

To get the number of matched rows, try doing a SELECT query before you do the UPDATE query. I don't know if that will produce the results you're looking for, but it might.

Yeah, the extra select is what I was hoping to avoid :-P The MySQL client will return both the number of rows matched and the number of rows affected by the query; I was hoping perhaps the PHP API offered a way for me to do the same.

Ah well... Thanks! You can access data about the latest query via mysql_info() http://php.net/manual/en/function.mysql-info.php You can parse the string for the values you need. There may be a more elegant solution.
