我博客上的图片原来都存放在www.zyan.cc服务器上,由于该服务器不稳定,于是我将所有图片切换到了blog.zyan.cc服务器上,同时在MySQL数据库中,将字符串www.zyan.cc批量替换为blog.zyan.cc。为了方便以后使用,我将这条“将字符串aaa批量替换为bbb”的SQL语句记录在此:
引用
UPDATE 表名 SET 字段名 = REPLACE (字段名, 'aaa', 'bbb');

大哥哥,我想请教你,我想学习一些数据库的基础。

请问能推荐写书吗?

我没买过多少书,基本上是看是MySQL数据库的官方参考手册,以及比较出色的产品的源代码,这里是MySQL 5.1的中文手册,你可以看一下:
