法律研究MySQL LIKE 查询带动态数组？
要实现带有动态数组的 LIKE 查询，语法如下 –
示例
select *from yourTableName where yourColumnName2 like "%yourValue%" order by yourColumnName1 asc limit yourLimitValue;
让我们创建一个表 –
示例
mysql> create table demo74 -> ( -> user_id int not null auto_increment primary key, -> user_names varchar(250) -> ) -> ; Query OK, 0 rows affected (0.67
借助 insert 命令向表中插入一些记录 –
示例
mysql> insert into demo74(user_names) values("John Smith1,John Smith2,John Smith3");
Query OK, 1 row affected (0.18
mysql> insert into demo74(user_names) values("John Smith1");
Query OK, 1 row affected (0.15
mysql> insert into demo74(user_names) values("David Smith1");
Query OK, 1 row affected (0.12
mysql> insert into demo74(user_names) values("John Smith1,John Smith2,John Smith3,John Smith4");
Query OK, 1 row affected (0.10使用 select 语句从表中显示记录 –
示例
mysql> select *from demo74;
这将生成以下输出 –
输出
+---------+-------------------------------------------------+
| user_id | user_names |
+---------+-------------------------------------------------+
| 1 | John Smith1,John Smith2,John Smith3 |
| 2 | John Smith1 |
| 3 | David Smith1 |
| 4 | John Smith1,John Smith2,John Smith3,John Smith4 |
+---------+-------------------------------------------------+
以下是带有动态数组的 MySQL LIKE 查询 –
示例
mysql> select *from demo74 -> where user_names like "%John Smith1%" -> order by user_id asc -> limit 100;
这将生成以下输出 –
输出
+---------+-------------------------------------------------+
| user_id | user_names |
+---------+-------------------------------------------------+
| 1 | John Smith1,John Smith2,John Smith3 |
| 2 | John Smith1 |
| 4 | John Smith1,John Smith2,John Smith3,John Smith4 |
+---------+-------------------------------------------------+
