首先我们创建一个表 −
mysql> create table DemoTable664 (CityName varchar(100)); Query OK, 0 rows affected (0.89 sec)
使用 insert 命令在表中插入一些记录 −
mysql> insert into DemoTable664 values('Springfield');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable664 values('Austin');
Query OK, 1 row affected (0.30 sec)
mysql> insert into DemoTable664 values('Franklin');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable664 values('OAKLAND');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable664 values('Anchorage');
Query OK, 1 row affected (0.18 sec)
使用 select 语句显示表中的所有记录 −
mysql> select *from DemoTable664;
这将产生以下输出 −
+-------------+ | CityName | +-------------+ | Springfield | | Austin | | Franklin | | OAKLAND | | Anchorage | +-------------+ 5 rows in set (0.00 sec)
以下查询使用 RLIKE/REGEXP 模式，当列值以 2 个元音字母开头时显示记录 −
mysql> select *from DemoTable664 where CityName RLIKE '^[aeiouAEIOU][aeiouAEIOU]';
这将产生以下输出 −
+----------+ | CityName | +----------+ | Austin | | OAKLAND | +----------+ 2 rows in set (0.00 sec)
