Mysql显示名称，SUM（金额）WHERE金额小于210且SUM（金额）大于或等于210

Question

Mysql表

Name   | Amount
------------
name1  | 150
name1  | 90
name2  | 100
name2  | 110
name3  | 10

结果需要像

这样的东西

Name   | SUM(Amount)
------------
name1  | 240
name2  | 210

尝试

 SELECT Name, SUM(Amount)
 WHERE Amount < 210 AND SUM(Amount) >= 210
 GROUP BY Name

但是得到错误SQLSTATE[HY000]: General error: 1111 Invalid use of group function

如果我移除AND SUM(Amount) >= 210代码

试图思考......我是否需要首先获得SUM(Amount) AS SumAmount并在同一个查询中而不是AND SUM(Amount) >= 210使用AND SumAmount >= 210？ ...但在一个查询中有两个SELECT ...

喜欢什么？

 SELECT SUM(Amount) AS SumAmount
 WHERE Amount < 210
 GROUP BY Name

 SELECT Name, SUM(Amount)
 WHERE SumAmount >= 210
 GROUP BY Name

请，建议

Answer 1

使用HAVING子句过滤汇总结果，例如SUM()等

SELECT Name, SUM(Amount)
FROM   tableName
WHERE  Amount < 210
GROUP  BY Name
HAVING SUM(Amount) >= 210
