要根据关键字显示结果,请使用 LIKE 运算符,语法如下 −

select *from yourTableName where yourColumnName LIKE '%yourValue%';

首先我们创建一个表 −

mysql> create table DemoTable812(Comments text);
Query OK, 0 rows affected (0.61 sec)

使用 insert 命令在表中插入一些记录 −

mysql> insert into DemoTable812 values('Good Looking');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable812 values('Awesome');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable812 values('Looking Gorgeous');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable812 values('Good Luck');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable812 values('Have a nice day');
Query OK, 1 row affected (0.21 sec)

使用 select 语句显示表中的所有记录 −

mysql> select *from DemoTable812;

这将产生以下输出 −

+------------------+
| Comments         |
+------------------+
| Good Looking     |
| Awesome          |
| Looking Gorgeous |
| Good Luck        |
| Have a nice day  |
+------------------+
5 rows in set (0.00 sec)

以下是使用 MySQL LIKE 创建搜索系统并根据关键字显示结果的查询 −
