数据|数据库|语句

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

自动生成添加表格,并产生相关sql添加语句,生成UPDATE语句(简单版)
