以前我有讲过关于在mysql中利用update和replace函数来实现批量替换我们指定的内容，其实方法很简单的有需要的朋友看看

批量替换的具体语法是：

代码如下	复制代码
UPDATE 表名 SET 指定字段 = replace(指定字段, ’要替换的字符串’, ’想要的字符串’) WHERE 条件;

如果你想把 article 表中 ID 小于5000的记录，content 字段中“解决”替换成“解放”，那么语法就是：

代码如下	复制代码
UPDATE article SET content = replace(content, ’解决’, ’解放’) WHERE ID

后面的where可以自己定义哦，好了喜欢就看看吧。

Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3.
