Re: SELECT COUNT from multiple tables

you can't aggregate a wildcard like count(*), because you'd not be giving it any group by field. the way to do it would be like this...

SELECT field1, count(field2) as count FROM table where field3='role' GROUP BY field1

substitute in your own field and table names, joins etc, but that's how you get a good count.
