我现在只想从几千条记录中选择计数大于 1 的行(换句话说，重复项)我主要看到的是 1 和一些 2 和 3
SELECT count( * ) AS `Number` , GI . *
FROM `GeneralInformation` AS GI
GROUP BY `FirstName` , `Surname`
我该怎么做？
最佳答案
SELECT count( * ) AS `Number` , GI . *
FROM `GeneralInformation` AS GI
GROUP BY `FirstName` , `Surname`
HAVING count(*)>1
关于mysql - 使用 GROUP BY 检索满足条件的记录，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/1997307/
