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

mysql替换表的字段里面内容,如例子:

因为服务器上安了头号拦截类别,所以dede的更替功能倒霉使.只可以手动在phpadmin中SQL:
update dede_addonarticle  set body=replace(body ,'大法','方法') 

主干语句:

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 id,type from items limit 10;
