按多个ID排序MySQL查询?
为此,请使用ORDER BY FIELD()
。让我们首先创建一个表-
mysql> create table DemoTable(ClientId varchar(40),
ClientName varchar(40)
);
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('987_John','John');mysql> insert into DemoTable values('1000_Sam','Sam');
mysql> insert into DemoTable values('777_Carol','Carol');
mysql> insert into DemoTable values('2000_Bob','Bob');
使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
这将产生以下输出-
+-----------+------------+| ClientId | ClientName |
+-----------+------------+
| 987_John | John |
| 1000_Sam | Sam |
| 777_Carol | Carol |
| 2000_Bob | Bob |
+-----------+------------+
4 rows in set (0.00 sec)
以下是按多个ID排序MySQL查询的查询-
mysql> select *from DemoTableorder by field(ClientId,'1000_Sam','2000_Bob','777_Carol','987_John');
这将产生以下输出-

+-----------+------------+
| 1000_Sam | Sam |
| 2000_Bob | Bob |
