1,获取返回表
    declare @sql varchar(1000)
    
    set @sql=N'select * from Student'
    
    --exec(@sql)
    
    create table #S
    
    (
    
    #SStudentID int--#S表结构和Student一致
    
    )
    
    insert into #S exec(@sql)--把返回的结果报错到临时表里
    
    select * from #S--对临时表操作
    
    drop table #S
  
2,获取单个变量
    declare @sql varchar(1000),@var int
    
    set @sql=N'select * from Student'
    
    --exec(@sql)
    
    
      If   Object_Id( 'Tempdb.dbo.#S')   Is   Not   NULL
    
    --#Test 为临时表名 
    
      begin
    
      Print 'Exists Table'
    
      drop table #S
    
      end
    
    Else begin
    
      Print 'Not Exists Table'
    
    create table #S
    
    (
    
    #SStudentID int
    
    )
    
    end
    
    insert into #S exec(@sql)--把返回的结果报错到临时表里
    
    select * from #S--对临时表操作
    
    set @var=(select top 1 #SStudentID from #S)
    
    select @var
    
    drop table #S
  
注:判断表是否存在:
    IF EXISTS (Select * From sysObjects Where Name ='Student' And Type In ('S','U'))
    
     PRINT 'exists'
    
    ELSE
    
     PRINT 'not exists'
    
    GO
