I have the following (shortened query): SELECT `Statistics`.`StatisticID`, COUNT(DISTINCT `Flags`.`FlagType`) AS `FlagCount` FROM `Statistics`

I have the following (shortened query):

SELECT      `Statistics`.`StatisticID`,     COUNT(DISTINCT `Flags`.`FlagType`) AS `FlagCount` FROM `Statistics` LEFT JOIN `Flags` ON `Statistics`.`StatisticID` = `Flags`.`StatisticID` WHERE `FlagCount` = 0 GROUP BY `Statistics`.`StatisticID` ORDER BY `SubmittedTime` DESC LIMIT 0, 10

Now, neither FlagCount = 0 or COUNT(Flags.FlagType) work in the WHERE clause. I thought about using a SET but I’m not sure how I’d add that to the query. Any ideas?

Thanks,

  1. Maybe you can try subquerying if HAVING doesn’t work.

    SELECT      `Statistics`.`StatisticID`,     COUNT(DISTINCT `Flags`.`FlagType`) AS `FlagCount` FROM `Statistics`     LEFT JOIN `Flags` ON `Statistics`.`StatisticID` = `Flags`.`StatisticID` WHERE `Statistics`.`StatisticID`   IN (SELECT `Flags`.`StatisticID`        FROM `Flags`       HAVING COUNT(DISTINCT `Flags`.`FlagType`) <= 3       GROUP BY `Flags`.`StatisticID`   ) GROUP BY `Statistics`.`StatisticID` ORDER BY `SubmittedTime` DESC LIMIT 0, 10
