^全^ 获取SQL SERVER2000/2005、MySql、Oracle元数据的SQL语句(1)

前言

     前段时间老赵发了一篇关于和谐社区，和谐技术：微软的宠儿们，为什么富人的孩子就不能早当家？引发的争论至今令我诚惶诚恐，说得很在理！！这篇文章本打算放首页的，但是由于是拿来主义，我认为这属于新手的典型特征之一(本来就是新手=_=)，故老老实实的放新手区吧。心里比较踏实一点，即使看到的人不多也没关系，自己做个笔记 :)

     有很多朋友都比较关心代码自动生成，理所当然离不开元数据了，但是对于获取元数据的方法不一。由于最近我也在写代码生成，对元数据的获取SQL语句并不齐全，意外的想到了CodeSmith，它也可以根据元数据来生成三层的，于是乎习惯性的去找他的源码了，果然没有失望，我们在SchemaProviders目录下能看到如下文件：

SchemaExplorer.ADOXSchemaProvider.dll

SchemaExplorer.MySQLSchemaProvider.dll

SchemaExplorer.OracleSchemaProvider.dll

SchemaExplorer.SqlSchemaProvider.dll

没有加密！但是SchemaExplorer.SqlSchemaProvider.dll混淆了！用Reflector查看源代码仍然能看到SQL语句，于是乎拷贝出来，替换\t\n，弄了我两个小时才完，今天一搜，原来有源码- - ！！超级郁闷！！大伙就别走我的弯路了吧！源码在Samples\Projects\目录下。下面开始Ctrl+C，然后Ctrl+V，贴上来给没有下载CodeSmith的朋友收藏一下吧:)
