我有多个表需要合并为一个。
SELECT name, SUM(money) AS MONEY FROM transactions
JOIN results ON transactions.id = results.id
JOIN more ON results.per_id = more.per_id
GROUP BY name
输出是人名(第一栏)和人的钱(第二栏)。
name | money
aaron 1220
mike 800
john 200
kate 600
现在我尝试按金额过滤结果,即显示“Sum(money)> 500”的人的结果
因为这个原因我试着把“WHERE money> 500 GROUP BY name”但输出错了(aaron 1000,mike 610等)。
如何编写查询来过滤最后/结束结果?
答案 0 :(得分:4)
Group By Name
having sum(money) > 500
编辑:你对“最后/结局结果”有什么看法?
答案 1 :(得分:4)
如果您希望SUM(money)
大于500,那么您可以这样做:
SELECT name, SUM(money) AS MONEY FROM transactions
JOIN results ON transactions.id = results.id
JOIN more ON results.per_id = more.per_id
GROUP BY name
HAVING SUM(money)>500
