Re: Returning where COUNT 5
With a join and group by I think you have HAVING. Hi all how to do this in MySQL? Returning only records with COUNT 5? SELECT `groups`.`groupsDescr`, `roles`.`roles_Agroup`, `roles`.`rolesDescr`, COUNT(`roles`.`rolesDescr`) AS TOTAL FROM `roles` INNER JOIN `groups_roles` ON (`roles`.`rolesID` = `groups_roles`.`fkrolesID`) INNER JOIN `groups` ON (`groups_roles`.`fkgroupsID` = `groups`.`groupsID`) GROUP BY `roles`.`rolesDescr` WHERE COUNT(`roles`.`rolesDescr`) GT 5 MySQL 4.0.12 give an error... maybe because i'm using WHERE COUNT? Thanx for your time. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Returning where COUNT 5
You cannot do that in the WHERE clause. The WHERE clause determines which rows to look at. That is, in this case, it determines which rows to count. How can it choose which rows to count based on the result of the count? See the problem? Instead, you need to use the HAVING clause, which filters at the end (after the counting), like this: SELECT g.groupsDescr, r.roles_Agroup, r.rolesDescr, COUNT(r.rolesDescr) AS TOTAL FROM roles r INNER JOIN groups_roles gr ON (r.rolesID = gr.fkrolesID) INNER JOIN groups g ON (gr.fkgroupsID = g.groupsID) GROUP BY r.rolesDescr HAVING TOTAL 5; Michael ColdFusion Lists wrote: Hi all how to do this in MySQL?
