SQL 视图结构

[lsj_zrp]

有没有办法通过SQL语句查询到视图是如何生成的？
谢谢！

sp_helptext

sp_helptext

[AcHerat]

create view v1
as
select top 10 *
from hy_fz_productTicketInfo
go

exec sp_helptext v1

drop view v1

/************

Text
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
create view v1
as
select top 10 *
from hy_fz_productTicketInfo

还有object_definition函数.

create view v1
as
select top 10 * from sysobjects
go

select object_definition(object_id('v1')) code

code
---------------------------------
create view v1
as
select top 10 * from sysobjects

也可用

CREATE VIEW v
AS
SELECT 1 AS ID
go
SELECT text FROM syscomments WHERE ID=OBJECT_ID('v')

         when 2 then 'IsView'
         when 3 then 'IsTrigger'
         when 4 then 'IsProcedure' 
         when 5 then 'IsDefault'   
         when 6 then 'IsForeignKey'
         when 7 then 'IsScalarFunction'

         when 9 then 'IsPrimaryKey'
         when 10 then 'IsExtendedProc'    
         when 11 then 'IsReplProc'
         when 12 then 'IsRule'
                  end
 /* Create the select */
 /* Use @isobject variable isstead of IsUserTable string */
EXEC(N'declare hCForEach cursor global for select ''['' + REPLACE(user_name(uid), N'']'', N'']]'') + '']'' + ''.'' + ''['' + 
REPLACE(object_name(id), N'']'', N'']]'') + '']'' from dbo.sysobjects o '
        + N' where OBJECTPROPERTY(o.id, N'''+@isobject+''') = 1 '+N' and o.category & ' + @mscat + N' = 0 '
       + @whereand)
 declare @retval int
 select @retval = @@error
 if (@retval = 0)
  exec @retval = sp_MSforeach_worker @command1, @replacechar, @command2, @command3
 if (@retval = 0 and @postcommand is not null)
  exec(@postcommand)
 return @retval
GO

这样我们来测试一下:
   --获得所有的存储过程的脚本:
         EXEc sp_MSforeachObject @command1="sp_helptext '?' ",@objectType=4
   --获得所有的视图的脚本:
         EXEc sp_MSforeachObject @command1="sp_helptext '?' ",@objectType=2

只能通过视图创建语句去分析,系统表中只记录两个东西,一是在sysobjects表中记录视图的一些属性,另一个是在syscolumns表中记录视图所查的列的属性.
