如何使用RegExp在MySQL中搜索特定单词？
让我们首先创建一个表-
mysql> create table DemoTable -> ( -> Title varchar(255) -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('John is a good player');
mysql> insert into DemoTable values('No,John Doe is not a good player');
mysql> insert into DemoTable values('Yes,Adam Smith is play cricket match');
mysql> alter table DemoTable add fulltext(Title);
Records: 0 Duplicates: 0 Warnings: 1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-
+--------------------------------------+ | Title | +--------------------------------------+ | John is a good player | | No,John Doe is not a good player | | Yes,Adam Smith is play cricket match | +--------------------------------------+ 3 rows in set (0.00 sec)
这是在MySQL中搜索特定单词的查询-
mysql> select *from DemoTable -> where Title REGEXP '^.*John.*$';
这将产生以下输出-
+----------------------------------+ | Title | +----------------------------------+ | John is a good player | | No,John Doe is not a good player | +----------------------------------+ 2 rows in set (0.11 sec)
