多层开发中，经常写SQL SERVER存储过程的朋友看过来!

莫问

　　
　　下面是自动产生存储过程的sql 脚本,你可以在查询分析器中运行.
　　运行完,你会看到多了四个存储过程
　　pr__SYS_MakeInsertRecordProc
　　pr__SYS_MakeUpdateRecordProc
　　pr__SYS_MakeSelectRecordProc
　　pr__SYS_MakeDeleteRecordProc
　　执行方式：在查询分析器中执行
　　pr__SYS_MakeInsertRecordProc '表名' --得到插入语句
　　pr__SYS_MakeInsertRecordProc '表名',1　 --得到插入语句，并创建Insert存储过程
　　
　　完整脚本如下:
