Hi Critters, The problem is that as your MySQL is 4.0.21 don't suport the subselect you would need to do the group.
I was thinking and you have another alternative: CREATE TEMPORARY table tdata (SELECT f1 as 'domain' from sends) union all (SELECT f2 as 'domain' from sends) union all (SELECT f3 as 'domain' from sends) union all (SELECT f4 as 'domain' from sends); -- This would create an temporary table with all the data SELECT domain,count(*) from tdata GROUP by domain; -- This sould do the trick. mpneves On Thursday 19 January 2006 16:14, Critters wrote: > Thanks for the replies Marco... > mysql Ver 12.22 Distrib 4.0.21 > > So that could be it? > > By the way... > > (SELECT f1 as 'domain' from sends) union > (SELECT f2 as 'domain' from sends) union > (SELECT f3 as 'domain' from sends) union > (SELECT f4 as 'domain' from sends) > > Works, and returns a list where f1, f2, f3 and f4 are all in the column > "domain" > > But as soon as I add "GROUP BY domain" to the end it fails.
