使用MySQL实施特定的记录排序
要设置特定的记录顺序，请使用ORDERBYLIKE。让我们首先创建一个表-
mysql> create table DemoTable808(Value varchar(100));
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable808 values('smith');
mysql> insert into DemoTable808 values('Adamsmith');
mysql> insert into DemoTable808 values('Carolsmith');
mysql> insert into DemoTable808 values('smithJohn');使用select语句显示表中的所有记录-
mysql> select *from DemoTable808;
这将产生以下输出-
+------------+ | Value | +------------+ | smith | | Adamsmith | | Carolsmith | | smithJohn | +------------+ 4 rows in set (0.00 sec)
以下是设置特定顺序的查询-
mysql> select *from DemoTable808 order by case when Value like 'smith%' then 0 else 1 end asc,Value asc;
这将产生以下输出-
+------------+ | Value | +------------+ | smith | | smithJohn | | Adamsmith | | Carolsmith | +------------+ 4 rows in set (0.00 sec)
