利用脚本修改SQL SERVER排序规则
编写人：CC阿爸
2014-3-1
l 今年的一项重要工作是对公司所用系统进行繁简的转换，程序转成简体基本很容易解决，但数据库转换成简体，就没那么容易了。经测试发现，简体的数据库，可以完美的支持到繁简体同时存储，并且不用更换任何数据类型，没想到SQL升级到2005后，微软如此的厚爱大陆市场，其它的话不多说了，罗列一下，本次转换数据库的相关步骤，
从网上看到有部分好人，有相关的转换代码，其根源是老外写的，但往往直接拿来用是不行的，还必须对其进行修正，该代码只考虑了，约速束主键和外键，未考虑到检查约束，统计信息，因此决定还是写在博客中，方便日后查找，需要的同学可供参考。
经过在网上搜索部分解决方案，在此基础上进行修正，解决方案才是正解。
