MySQL - 选择Sum（rows）= something的行

Question

我有3列

detail_id, item_id, item_qty

我想：

SELECT detail_id FROM tbl_details WHERE SUM(item_qty) = some value

我试图在这里找到答案但失败了，如果有人可以提供简单有效的查询，我将非常感谢您的帮助。

此致

Answer 1

尝试使用拥有子句

text/plain

Answer 2

您不能将WHERE子句用于聚合函数..使用Group BY & Having .. this discussion。 e.g ...

SELECT detail_id , SUM(item_qty) total_item
FROM tbl_details 
GROUP BY detail_id 
HAVING total_item = some_value
