mysql替换表中的字符串的sql语句

核心语句：

UPDATE `cdb_pms` SET `subject` = REPLACE(`subject`, 'Welcome to', '欢迎光临')

mysql/' target='_blank'>mysql替换字段里数据内容部分字符串

MySQL替换表的字段里面内容，如例子：

mysql> select host,user from user where user='testuser';
+-----------------------+----------+
| host | user |
+-----------------------+----------+
| localhost.localdomain | testuser |
+-----------------------+----------+

update字段host的内容，把"main"改成"slave",用REPLACE

mysql> update user set host=REPLACE(host,'main','slave') where user='testuser';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0

mysql> select host,user from user where user='testuser';
+------------------------+----------+
| host | user |
+------------------------+----------+
| localhost.localdoslave | testuser |
+------------------------+----------+

由查询结果到，数据已经更新成功


因为服务器上安了一流拦截系统,所以dede的交替功能不好使.只能手动在phpadmin中SQL:
updatedede_addonarticlesetbody=replace(body,'大法','方法')

mysql替换表的字段里面内容，如例子：

mysql> select id,type from items limit 10;
+--------+--------+
| id | type |
+--------+--------+
| 0001 | 780000 |
| 0002 | 780000 |
| 0003 | 780000 |
| 0004 | 780000 |
| 0005 | 780000 |
| 150419 | 780000 |
| 150420 | 780000 |
| 150421 | 780000 |
| 150422 | 780000 |
| 150423 | 780000 |
+--------+--------+

把type字段中的“78”改成“79” 用replace函数

sql如下：

mysql> update items set type=replace(type,'79','78');

Query OK, 17536 rows affected (0.72 sec)
Rows matched: 17536 Changed: 17536 Warnings: 0
再查询：

mysql> select id,type from items limit 10;
+--------+--------+
| id | type |
+--------+--------+
| 0001 | 790000 |
| 0002 | 790000 |
| 0003 | 790000 |
| 0004 | 790000 |
| 0005 | 790000 |
| 150419 | 790000 |
| 150420 | 790000 |
| 150421 | 790000 |
| 150422 | 790000 |
| 150423 | 790000 |
+--------+--------+
10 rows in set (0.00 sec)
