要以特定顺序显示记录列表,您需要设置条件并使用ORDER BY。为此,请使用ORDER BY CASE语句。让我们首先创建一个表-
mysql> create table DemoTable2039 -> ( -> Name varchar(20) -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable2039 values('John Doe'); mysql> insert into DemoTable2039 values('John Smith'); mysql> insert into DemoTable2039 values('Chris Brown'); mysql> insert into DemoTable2039 values('Adam Smith'); mysql> insert into DemoTable2039 values('David Miller');
使用select语句显示表中的所有记录-
mysql> select *from DemoTable2039;
这将产生以下输出-
+--------------+ | Name | +--------------+ | John Doe | | John Smith | | Chris Brown | | Adam Smith | | David Miller | +--------------+ 5 rows in set (0.00 sec)
这是查询以ASC顺序显示特定记录列表-
mysql> select *from DemoTable2039 -> order by -> case when Name like '%Smith%' then 101 -> else -> 100 -> end, -> Name;
这将产生以下输出-
+--------------+ | Name | +--------------+ | Chris Brown | | David Miller | | John Doe | | Adam Smith | | John Smith | +--------------+ 5 rows in set (0.37 sec)
