MySQL查询“哪里SUM（价格）大于等于”？

Question

这是我的查询：

SELECT user,name,SUM(price) FROM $tableName WHERE faktor='1' GROUP BY user ORDER BY SUM(price) ASC

此查询工作，但我想显示谁有总和（价格）大于100 $。 我用WHERE SUM(Price) < '100'测试它但不起作用，结果是错误的。

谢谢;）

Answer 1

您需要使用HAVING，而不是WHERE。

SELECT user,name,SUM(price)
  FROM $tableName
  WHERE faktor='1'
  GROUP BY user
  HAVING SUM(price) < 100
  ORDER BY SUM(price) ASC

在进行分组之前，

WHERE适用。 HAVING适用于后缀。

Answer 2

要评估查询中累积函数的值，您需要使用查询的HAVING clause。

Answer 3

尝试使用HAVING

SELECT user,name,SUM(price) FROM $tableName WHERE faktor='1'
GROUP BY user
HAVING SUM(Price) < 100
ORDER BY SUM(price) ASC

Answer 4

查找HAVING - sql子句。它充当WHERE但适用于GROUP：

SELECT user,name,SUM(price) 
FROM $tableName 
WHERE faktor='1' 
GROUP BY user 
HAVING SUM(price) > 100
ORDER BY SUM(price) ASC
