   本来不想告诉大家的,因为采集别人网站不是什么光彩事,但觉得这个技巧实在是够强,要不是这简短的一行代码,我还不累死了。是这样的,采集了一些别人的文章,可能是采集程序的问题,每篇文章的标题里都多出了一些字符 在SQL语句中使用replace替换字符 导致在生成HTML网页后很多内容不显示,但是看了看记录有2000多条,一条一条改,还不累死我啊。于是请教了一个SQL高手,发我一行SQL语句:

update `article` set title=replace(title,' 在SQL语句中使用replace替换字符','');

  执行完什么也没见到,可我看了一下数据库,哇塞!!真爽了,在SQL语句中使用replace替换字符全部都不见了,觉得这个语句真够猛的,也怪自己不懂SQL竟然有如此用法啊,以后要多多研究sql了,事半功倍啊。所以不敢独享本经验,特此与大家分享。另外报告,俺现在已经不搞采集了,,就像做人一样老实做站,期待大家的站也有好收成。顺便说下这行代码的含义:

  update '表名(比如我的article)' set 要修改的字段名 = replace (要修改的字段名,'被替换的字符','替换后的字符')
