I\'d like to only select the rows where the count is greater than 1 (in other words the duplicates) right now from a few thousand records I am mostly seeing 1s with a few 2s

    SELECT count( * ) AS `Number` , GI . *
    FROM `GeneralInformation` AS GI
    GROUP BY `FirstName` , `Surname` 
    HAVING count(*)>1
