为此，可以将WHERE子句与多个LIKE一起使用。让我们首先创建一个表-

create table DemoTable1536
   -> (
   -> Sentence text
   -> );

使用插入命令在表中插入一些记录-

insert into DemoTable1536 values('I like MySQL database.');
insert into DemoTable1536 values('Java is an Object Oriented Programming Language');
insert into DemoTable1536 values('I only like data structure');
insert into DemoTable1536 values('MongoDB is NoSQL database');

使用select语句显示表中的所有记录-

select * from DemoTable1536;

这将产生以下输出-

+--------------------------------------------------+
| Sentence                                         |
+--------------------------------------------------+
| I like MySQL database.                           |
| Java is an Object Oriented Programming Language  |
| I only like data structure                       |
| MongoDB is NoSQL database                        |
+--------------------------------------------------+
4 rows in set (0.00 sec)

以下是查询多个单词的查询-

select * from DemoTable1536
   -> where ( Sentence like '%like%') or (Sentence like '%database%') or (Sentence like '%data%');

这将产生以下输出-

+----------------------------+
| Sentence                   |
+----------------------------+
| I like MySQL database.     |
| I only like data structure |
| MongoDB is NoSQL database  |
+----------------------------+
3 rows in set (0.00 sec)
