视图中不能声明变量，不能调用存储过程，如果写比较复杂的查询，需要应用存储过程

视图也可以和函数结合

存储过程通过select或其他语句返回结果集

除此之外，存储过程返回结果只有两种方式 1 return，2 output参数（主要）

IF  EXISTS (SELECT * FROM sysobjects WHERE id = OBJECT_ID(N'[dbo].[GL_AllItemNamep]','p')    ) --视图v ,存储过程p，表u
DROP proc[dbo].[GL_AllItemNamep]
GO
create proc gl_allitemnamep @tblname as nvarchar(200) --注意此处没有括号
as
declare @sql as nvarchar(2000)
 set @sql='' --不赋值，在使用@sql=@sql+'.....' 不能初始化
 SET @sql = '
 if exists( select * from sysobjects where id=object_id('''+ @tblname + ''') and type=''u'')
 drop table ' +@tblname
 print @sql
 EXEC(@sql)
    set @sql='if not exists(select 1 from tempdb..sysobjects where name='''+@tblname +''' and xtype=''u'')
                    select ''97'' as citem_class,citemcode,citemname  into '+@tblname +' from  fitemss97 where 1=0 ' --应用where 1=0 建立数据表结构，再用insert into 插入数据，对于大数据量来说会比select into 效率高
    exec(@sql)
 print @sql
 set @sql=''
 declare @citem_class as nvarchar(10)
 declare @ctable as nvarchar(100)
 declare @cur as cursor
 set @cur=CURSOR FOR( select citem_class ,ctable from fitemclass)
 open @cur
 fetch @cur into @citem_class,@ctable

while @@FETCH_STATUS =0
 begin
  print @sql
  set @sql= @sql+ ' union select N''' + @citem_class + ''' as citem_class,citemcode,citemname  from  ' + @ctable + ' '
  fetch next from @cur into @citem_class,@ctable
 end
 close @cur
 deallocate @cur

 exec (@sql)
 print @sql
 
go

执行

exec GL_AllItemNamep 'AllItemName'
  select * from AllItemName
