Subject: Re: Get lines matching a select / group by query
Use COUNT():
SELECT COUNT( id ) FROM test WHERE LEFT( id, 5 ) = '12345' GROUP BY value;

Hello,
unfortunately that is what I tried (I didn't posted my query correctly as I didn't use cut and past - sorry)
It will return the count of lines for each pairs of "group by"

I like to get the number of lines returned by a select ... group by query:
Example:

Perhaps I will get
+-----------+ | id | +-----------+ | 2 | | 1 | | 5 | +-----------+ 3 rows in set (0.02 sec)
But I like to simply get 3
As I use mySQL 3.x and can't change it for now I'm not able to use "FOUND_ROWS()"
Thanks,
