如何在MySQL中仅显示总和小于150的列值？按降序排列结果
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)
