MySQL查询以LIKE和OR进行文本搜索以获取记录
让我们首先创建一个表-
mysql> create table DemoTable ( Subject text );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('Introduction to MySQL');
mysql> insert into DemoTable values('Deep Dive using Java');
mysql> insert into DemoTable values('C in Depth');
mysql> insert into DemoTable values('Introduction to C++');使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
这将产生以下输出-
+-----------------------+ | Subject | +-----------------------+ | Introduction to MySQL | | Deep Dive using Java | | C in Depth | | Introduction to C++ | +-----------------------+ 4 rows in set (0.00 sec)
以下是使用LIKE和OR进行文本搜索的查询-
mysql> select *from DemoTable where Subject LIKE '%MySQL%' OR Subject LIKE '%using%';
这将产生以下输出-
+-----------------------+ | Subject | +-----------------------+ | Introduction to MySQL | | Deep Dive using Java | +-----------------------+ 2 rows in set (0.00 sec)
