MySQL 如何仅显示列值的总和小于 150？将结果按降序排列

为此，您可以使用子查询。让我们首先创建一个表 –

mysql> create table DemoTable844(
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   Amount int
);
Query OK, 0 rows affected (0.95 sec)

使用插入命令向表中插入一些记录 –

mysql> insert into DemoTable844(Amount) values(80);
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable844(Amount) values(100);
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable844(Amount) values(60);
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable844(Amount) values(40);
Query OK, 1 row affected (0.36 sec)
mysql> insert into DemoTable844(Amount) values(150);
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable844(Amount) values(24);
Query OK, 1 row affected (0.40 sec)

使用 select 语句显示表中的所有记录。以下是查询 –

mysql> select *from DemoTable844;

这将产生以下结果 –

+----+--------+
| Id | Amount |
+----+--------+
|  1 |     80 |
|  2 |    100 |
|  3 |     60 |
|  4 |     40 |
|  5 |    150 |
|  6 |     24 |
+----+--------+
6 rows in set (0.00 sec)

如何在 MySQL 中仅显示列值的总和小于 150

mysql> select *from DemoTable844 tbl
   where (select sum(Amount) from DemoTable844 where Amount <= tbl.Amount order by Amount) < 150
order by Id;

这将产生以下结果 –

+----+--------+
| Id | Amount |
+----+--------+
|  3 |     60 |
|  4 |     40 |
|  6 |     24 |
+----+--------+
3 rows in set (0.26 sec)
