SQL 视图结构
有没有办法通过SQL语句查询到视图是如何生成的?
谢谢!

------解决方案--------------------
sp_helptext
------解决方案--------------------
sp_helptext
------解决方案--------------------
SQL code

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

------解决方案--------------------
还有object_definition函数.
SQL code

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

------解决方案--------------------
也可用
SQL code

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

------解决方案--------------------
SQL code
--批量查询
USE MASTER
GO
CREATE proc sp_MSforeachObject
 @objectType int=1,
 @command1 nvarchar(2000), 
 @replacechar nchar(1) = N'?', 
 @command2 nvarchar(2000) = null,
    @command3 nvarchar(2000) = null, 
 @whereand nvarchar(2000) = null,
 @precommand nvarchar(2000) = null, 
 @postcommand nvarchar(2000) = null
as
 /* This proc returns one or more rows for each table (optionally, matching @where), with each table defaulting to its 
own result set */
 /* @precommand and @postcommand may be used to force a single result set via a temp table. */
 /* Preprocessor won't replace within quotes so have to use str(). */
 declare @mscat nvarchar(12)
 select @mscat = ltrim(str(convert(int, 0x0002)))
 if (@precommand is not null)
  exec(@precommand)
 /* Defined  @isobject for save object type */
 Declare @isobject varchar(256)
 select @isobject= case @objectType when 1 then 'IsUserTable'
         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 8 then 'IsInlineFunction'
         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
