Question

我想根据分组的项目获取查询的某些结果的计数。我有这个问题：

SELECT c.name FROM tblCareers AS cc
INNER JOIN tblClusters AS c
ON c.careerid = cc.careerid
INNER JOIN @temp AS t
ON cc.userid = CurrentID

这给了我结果：

Agriculture
Healthcare
Agriculture

我希望能够返回的是：

Agriculture 2
Healthcare 1

所以我需要某种Count（c.name），但只返回：

Agriculture 1
Healthcare 1
Agriculture 1

有任何建议或如何？

谢谢！

您必须添加group by子句：

SELECT c.name, Count(*) FROM tblCareers AS cc
LEFTJOIN tblClusters AS c
ON c.careerid = cc.careerid
LEFT JOIN @temp AS t
ON cc.userid = CurrentID
Group by c.name
order by Count(*) DESC

检索分组项目的计数
