如何使用 MySQL LIKE 提取设置了多值的字段?
要在 MySQL 中使用带 OR 的 LIKE 提取带有多个值的字段 -
select *from yourTableName where yourColumnName like ‘%AnyStringValue’ or yourColumnName like ‘%AnyStringValue’ or yourColumnName like ‘%AnyStringValue’ ……...N;
你可以通过一个表来理解 -
mysql> create table LikeDemo −> ( −> Hobby varchar(200) −> ); Query OK, 0 rows affected (1.71 sec)
在表中插入一些记录,使用 insert 命令。在表中插入记录的查询如下 -
mysql> insert into LikeDemo values('Reading Book'); Query OK, 1 row affected (0.13 sec) mysql> insert into LikeDemo values('Playing Cricket Match'); Query OK, 1 row affected (0.16 sec) mysql> insert into LikeDemo values('Playing Hockey Match'); Query OK, 1 row affected (0.27 sec) mysql> insert into LikeDemo values('Reading Novel'); Query OK, 1 row affected (0.14 sec) mysql> insert into LikeDemo values('Swimming'); Query OK, 1 row affected (0.10 sec) Displaying all records with the help of select statement. The query is as follows: mysql> select *from LikeDemo;
以下是输出 -
+-----------------------+ | Hobby | +-----------------------+ | Reading Book | | Playing Cricket Match | | Playing Hockey Match | | Reading Novel | | Swimming | +-----------------------+ 5 rows in set (0.00 sec)
使用 LIKE 提取具有多个值的字段的查询如下 -
mysql> select *from LikeDemo where Hobby like '%Cricket%' or Hobby like '%Reading%';
以下是输出 -
+-----------------------+ | Hobby | +-----------------------+ | Reading Book | | Playing Cricket Match | | Reading Novel | +-----------------------+ 3 rows in set (0.00 sec)
