根据数据库自动生成insert/update更新语句

作者:网络 来源:佚名 更新时间:2008-02-08 13:08:08 点击:
在编写程序中,写添加和更新sql语句是一个比较烦琐的过程,特别是在表结构比较复杂的时候
这个程序主要是根据数据表格式自动生成添加/更新的sql语句,然后由程序员直接加入到程序中,方便编程

下面是文件,方法建立一个单独的文件,按照下面的说明建立相关文件,运行即可
index.php     索引文件
config.php    配置文件,转换get/post数据
addxxx.php    根据提交表格数据生成sql语句
addxxx2.php    根据数据库表信息生成sql语句,配置数据库在文件内部
