行转列,要调用上面的存储过程的结果集:

ALTER proc [dbo].[S_trend_row2column]
	   @B_time   varchar(30), 
       @E_time   varchar(30),
       @FunID    smallint
as      
begin  
	
	DECLARE @sql_str VARCHAR(8000)
		
    DECLARE @sql_col VARCHAR(8000);
	declare @demp table(MIDDLECLASS varchar(50),groupid int,period_sum int,period_min_date datetime,period_max_date datetime);
	
	insert into @demp exec S_trend @B_time,@E_time,0;
	--select * from @demp
	SELECT @sql_col = ISNULL(@sql_col + ',' , '') +  QUOTENAME(groupid)  FROM @demp GROUP BY groupid order by groupid  ;
	--print (@sql_col)
   
	SET @sql_str = '
 
	declare @demp table(MIDDLECLASS varchar(50),groupid varchar(50),period_sum int,period_min_date datetime,period_max_date datetime);
	
	insert into @demp exec S_trend '''+@B_time+''','''+@E_time+''',0;
 
 
	SELECT * FROM (
		SELECT [MIDDLECLASS],groupid,[period_sum] FROM @demp) p PIVOT 
		( SUM([period_sum]) FOR [groupid] IN ('+@sql_col+')
		) AS pvt ORDER BY pvt.[MIDDLECLASS]';
	
	--print (@sql_str)
	
    EXEC(@sql_str);
