C#网页版代码生成器

       C#网页版代码生成器，还在更新中....以前修复过ASPNETPAGER分页控件的网页版存储过程代码生成器，学到了一种思维，替换字符串，因此有空就写下了这个。仅供参考，本人水平还有待提高，写这个完全是兴趣，写的不好的地方不要骂我就行，呵呵。

存储过程代码如下，参考MSSQL SERVER文档。

存储过程代码

 7 where TABLE_CATALOG=N'+@dataBaseName+' order by TABLE_NAME ';                 --get the role !
 8 --SELECT * FROM INFORMATION_SCHEMA.TABLES 
 9 --where TABLE_CATALOG='TestSub' --get the schema from databse
10 exec(@sql);
11 print(@sql);
12 
13 ALTER  proc  [dbo].[GetColumnsFromTable]
14 @dataBaseName nvarchar(200),
15 @tableName nvarchar(200)
16 as
17 declare @dataBase  nvarchar(200);
18 set @dataBase=rtrim(@dataBaseName)+'.INFORMATION_SCHEMA.COLUMNS';
19 declare @sql nvarchar(2000);
20 --set @sql='SELECT TABLE_CATALOG, TABLE_SCHEMA, TABLE_NAME, COLUMN_NAME, COLUMN_DEFAULT
21 --FROM  '+@dataBaseName+'.INFORMATION_SCHEMA.COLUMNS
22 --WHERE TABLE_NAME =N'+@tableName+';'
23 set @sql='SELECT TABLE_CATALOG as "数据库", TABLE_SCHEMA as "表架构" , TABLE_NAME as "表名", COLUMN_NAME as "列名",DATA_TYPE  as "列数据类型"
24 FROM '+@dataBase
25 +' WHERE TABLE_NAME =N'+@tableName+' order by COLUMN_NAME';
26 exec(@sql);
27 print(@sql);
