【MSSQL】 SQL存储过程生成Model层

以下存储过程直接在数据库执行，然后按照示例调用即可。提供两种生成的代码样式

	样式一：Framework 3.5 以下适用

	SET ANSI_NULLS ON
	SET QUOTED_IDENTIFIER ON
	go
	CREATE PROC [dbo].[CreateEntityDown35]
	 @dbname VARCHAR(50) , --数据库名
	 @path VARCHAR(100) , --实体类所在目录名，如D:/My/Models
	 @namespace VARCHAR(50) --实体类命名空间,默认值为Models
	AS --判断数据库是否存在
	 IF ( DB_ID(@dbname) IS NOT NULL )
	 BEGIN
	 IF ( ISNULL(@namespace, '') = '' )
	 SET @namespace = 'Models'
	-- 允许配置高级选项
	 EXEC sp_configure 'show advanced options', 1
	-- 重新配置
	 RECONFIGURE
	-- 启用Ole Automation Procedures
	 EXEC sp_configure 'Ole Automation Procedures', 1
	-- 启用xp_cmdshell,可以向磁盘中写入文件
	 EXEC sp_configure 'xp_cmdshell', 1
	-- 重新配置
	 RECONFIGURE
	 DECLARE @dbsql VARCHAR(1000) ,
	 @tablename VARCHAR(100)
	 SET @dbsql = 'declare wsp cursor for select name from ' + @dbname
	 + '..sysobjects where xtype=''u'' and name <>''sysdiagrams'''
	 EXEC(@dbsql)
	 OPEN wsp
	 FETCH wsp INTO @tablename--使用游标循环遍历数据库中每个表
	 WHILE ( @@fetch_status = 0 )
	 BEGIN
	--根据表中字段组合实体类中的字段和属性
	 DECLARE @nsql NVARCHAR(4000) ,
