MySQL查询从字符串中搜索确切的单词？
要从字符串中搜索确切的单词，请使用以下语法-
select *from yourTableName where yourColumnName regexp '(^|[[:space:]])yourWord([[:space:]]|$)';
让我们首先创建一个表-
mysql> create table DemoTable ( Title text );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('This is the Introduction to Java');
mysql> insert into DemoTable values('This is the Introduction to MongoDB');
mysql> insert into DemoTable values('This is the Introduction to MySQL');使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
这将产生以下输出-
+-------------------------------------+ | Title | +-------------------------------------+ | This is the Introduction to Java | | This is the Introduction to MongoDB | | This is the Introduction to MySQL | +-------------------------------------+ 3 rows in set (0.00 sec)
以下是从字符串中搜索确切单词的查询。
mysql> select *from DemoTable where Title regexp '(^|[[:space:]])MySQL([[:space:]]|$)';
这将产生以下输出-
+-----------------------------------+ | Title | +-----------------------------------+ | This is the Introduction to MySQL | +-----------------------------------+ 1 row in set (0.13 sec)
