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
);

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable844(Amount) values(80);
mysql> insert into DemoTable844(Amount) values(100);
mysql> insert into DemoTable844(Amount) values(60);
mysql> insert into DemoTable844(Amount) values(40);
mysql> insert into DemoTable844(Amount) values(150);
mysql> insert into DemoTable844(Amount) values(24);

使用select语句显示表中的所有记录。以下是查询-

mysql> select *from DemoTable844;

这将产生以下输出-

+----+--------+
| 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中仅显示总和小于150的列值

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

这将产生以下输出-

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