让我们首先创建一个表-
create table DemoTable -> ( -> Words text -> );
使用插入命令在表中插入一些记录-
insert into DemoTable values('Ever'); insert into DemoTable values('Forever'); insert into DemoTable values('Good'); insert into DemoTable values('Never');
使用select语句显示表中的所有记录-
select *from DemoTable;
输出结果
+---------+ | Words | +---------+ | Ever | | Forever | | Good | | Never | +---------+ 4 rows in set (0.00 sec)
以下是两次查询以读取包含特定字符的记录的查询。在这里,我们正在搜索字符“ e”出现2次的记录-
select *from DemoTable where Words LIKE '%e%e%';
输出结果
+---------+ | Words | +---------+ | Ever | | Forever | | Never | +---------+ 3 rows in set (0.00 sec)
