具有列的最小值的行

Question

有这个选择:

id IDSLOT  N_UM
------------------------
1  1  6
2  6  2
3  2  1
4  4  1
5  5  1
6  8  1
7  3  1
8  7  1
9  9  1
10  10  0

我想获得具有最小值N_UM的行(仅一个),在这种情况下是id = 10(10 0)的行.

Answer 1

select * from TABLE_NAME order by COLUMN_NAME limit 1

Answer 2

我试试这个:

SELECT TOP 1 *
FROM TABLE1
ORDER BY N_UM

(使用SQL Server)

Answer 3

试试这个 -

 select top 1 * from table where N_UM = (select min(N_UM) from table);

Answer 4

使用这个SQL查询:

select id,IDSLOT,N_UM from table where N_UM = (select min(N_UM) from table));

Answer 5

方法1：

SELECT top 1 * 
FROM table 
WHERE N_UM = (SELECT min(N_UM) FROM table);

方法2：

SELECT * 
FROM table 
ORDER BY N_UM 
LIMIT 1

此类问题的更一般解决方案如下。

方法3：

SELECT *
FROM table 
WHERE N_UM IN (SELECT MIN(N_UM) FROM table);
