在MySQL中删除两个单词之间的空格?
为此,您可以使用REPLACE()
。让我们首先创建一个表-
mysql> create table DemoTable1506-> (
-> Title text
-> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1506 values('This is MySQL');mysql> insert into DemoTable1506 values('This is Java language');
mysql> insert into DemoTable1506 values('This is MongoDB NoSQL database');
使用select语句显示表中的所有记录-
mysql> select * from DemoTable1506;
这将产生以下输出-
+--------------------------------+| Title |
+--------------------------------+
| This is MySQL |
| This is Java language |
| This is MongoDB NoSQL database |
+--------------------------------+
3 rows in set (0.00 sec)
以下是删除两个单词之间的空格的查询-
mysql> update DemoTable1506-> set Title=replace(Title,' is ', ' is');
