要返回记录集顺序，您需要使用FIND_IN_SET()。让我们首先创建一个表-mysql> create table recordSetOrderDemo

-> (

-> EmployeeId int,

-> EmployeeName varchar(30)

-> );

以下是使用insert命令在表中插入一些记录的查询-mysql> insert into recordSetOrderDemo values(20,"John");

mysql> insert into recordSetOrderDemo values(10,"Larry");

mysql> insert into recordSetOrderDemo values(100,"Mike");

mysql> insert into recordSetOrderDemo values(50,"Sam");

mysql> insert into recordSetOrderDemo values(10,"David");

以下是使用select语句显示表中所有记录的查询-mysql> select *from recordSetOrderDemo;

这将产生以下输出-+------------+--------------+

| EmployeeId | EmployeeName |

+------------+--------------+

| 20         | John         |

| 10         | Larry        |

| 100        | Mike         |

| 50         | Sam          |

| 10         | David        |

+------------+--------------+

5 rows in set (0.00 sec)

以下是查询以返回记录集顺序-mysql> select *from recordSetOrderDemo where EmployeeId IN(100,10,20,50)

-> ORDER BY FIND_IN_SET(EmployeeId,'100,10,20,50');

这将产生以下输出-+------------+--------------+

| EmployeeId | EmployeeName |

+------------+--------------+

| 100        | Mike         |

| 10         | Larry        |

| 10         | David        |

| 20         | John         |

| 50         | Sam          |

+------------+--------------+

5 rows in set (0.03 sec)
