MySQL 如何执行字符串匹配

对于字符串匹配，请使用LIKE运算符。让我们首先创建一个表 –

mysql> create table DemoTable
   -> (
   -> MonthName varchar(100)
   -> );
Query OK, 0 rows affected (0.63 sec)

使用插入命令在表中插入一些记录 –

mysql> insert into DemoTable values('JFMA');
Query OK, 1 row affected (0.19 sec)

mysql> insert into DemoTable values('JMA');
Query OK, 1 row affected (0.16 sec)

mysql> insert into DemoTable values('JDN');
Query OK, 1 row affected (0.16 sec)

mysql> insert into DemoTable values('JFOSA');
Query OK, 1 row affected (0.19 sec)

使用select语句显示表中的所有记录 –

mysql> select *from DemoTable;
