根据上面的查询，我的理解远不止于此：
SELECT product_cd, SUM(avail_balance) prod_balance
FROM account
WHERE status = 'ACTIVE'
GROUP BY product_cd
结果是：
+------------+--------------+
| product_cd | prod_balance |
+------------+--------------+
| BUS | 9345.55 |
| CD | 19500.00 |
| CHK | 73008.01 |
| MM | 17045.14 |
| SAV | 1855.76 |
| SBL | 50000.00 |
+------------+--------------+
我的困惑是：
HAVING MIN(avail_balance) >= 1000
AND MAX(avail_balance) <= 10000;
我将其解释为：“仅包括余额大于或等于1,000且小于或等于10,000的余额”，这将导致
BUS: 9345.55SAV: 1855.76当我如上所述运行查询时，这是完全错误的。关于正在发生的事情的任何解释都将有所帮助。
最佳答案
尝试使用MIN（avail_balance）和MIN（avail_balance）代替
HAVING MIN(SUM(avail_balance)) >=1000
and MAX(SUM(avail_balance)) <=10000
您得到CD和MM的结果是因为它们的所有值都在1000到10000之间
关于mysql - MYSQL GROUP BY HAVING子句使用MIN和MAX作为范围，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/35138200/
