一个 MySQL 查询可用来从不同列值搜索多个单词
为此,可以使用 WHERE 子句与多个 LIKE。让我们先创建一个表 −
mysql> create table DemoTable1536 -> ( -> Sentence text -> ); Query OK, 0 rows affected (0.51 sec)
使用 insert 命令向表中插入一些记录 −
mysql> insert into DemoTable1536 values('I like MySQL database.'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable1536 values('Java is an Object Oriented Programming Language'); Query OK, 1 row affected (0.30 sec) mysql> insert into DemoTable1536 values('I only like data structure'); Query OK, 1 row affected (0.21 sec) mysql> insert into DemoTable1536 values('MongoDB is NoSQL database'); Query OK, 1 row affected (0.46 sec)
使用 select 语句显示表中的所有记录 −
mysql> select * from DemoTable1536;
这将生成以下输出 −
+--------------------------------------------------+ | 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)
以下是搜索多个单词的查询 −
mysql> select * from DemoTable1536 -> where ( Sentence like '%like%') or (Sentence like '%database%') or (Sentence like '%data%');
这将生成以下输出 −
+----------------------------+ | Sentence | +----------------------------+ | I like MySQL database. | | I only like data structure | | MongoDB is NoSQL database | +----------------------------+ 3 rows in set (0.00 sec)
