結合兩個存儲過程，一個存儲過程得到錯誤

Question

我有這樣一個存儲過程：

ALTER procedure [dbo].[IBS_PodiumSummeryCount] 
    @locid integer = null 
as 
begin 
    SET NOCOUNT ON; 

    SELECT 
     sum(status_receved) as Receved, 
     sum(status_parked) as Parked, 
     sum(status_requested) as Requested, 
     sum(status_requestedinprocess) as Requestinprocess 
    FROM 
     (SELECT 
      CASE WHEN (status = 0) THEN 1 ELSE 0 END AS status_receved, 
      CASE WHEN (status = 2) THEN 1 ELSE 0 END AS status_parked, 
      CASE WHEN (status = 3) THEN 1 ELSE 0 END AS status_requested, 
      CASE WHEN (status = 4) THEN 1 ELSE 0 END AS status_requestedinprocess 
     FROM 
      transaction_tbl 
     WHERE 
      locid = @locid AND dtime >= getdate()-1 AND status IN (0,2,3,4)) a; 

    SELECT 
     l1.StartTime, CONVERT(VARCHAR, GETDATE(), 108) AS Time 
    FROM 
     Location_tbl l1 
    WHERE 
     l1.Locid = @locid 
END 

我還有一個存儲過程是這樣的：

select dbo.podiumsummerytime(
       convert(decimal(10,1), 
        avg(convert(numeric(18,2), datediff(ss, t.dtime, t.PAICdate )))) 

      ) as Avgparkingtime, 
      dbo.podiumsummerytime(
       convert(decimal(10,1), 
        avg(convert(numeric(18,2), datediff(ss, t.Paydate, t.DelDate)))) 

      ) as AvgDelivarytime, 
      dbo.podiumsummerytime(
       convert(decimal(10,1), 
        avg(convert(numeric(18,2), datediff(ss, t.dtime, t.DelDate)))) 

      ) as Avgstaytime 

      from (select top 30 * from transaction_tbl where locid=@locid and dtime >= getdate()-2 order by transactID desc) t 
      end 

我試着寫這兩存儲過程在一個與工會，但我得到像這樣的錯誤：

所有使用UNION，INTERSECT或EXCEPT運算符組合的查詢m在目標列表中有相同數量的表達式。

我與SQL Server 2008中的工作，我怎麼能結合這兩種存儲過程轉換成一個存儲過程...

Answer 1

正如錯誤說，UNION是一個特定關鍵字的使用得到了一組包含兩個結果的行。如果行不同，那麼它們不能與UNION連接。

沒有什麼可以阻止你將兩個查詢放在一個存儲過程中，proc將只返回兩個結果集。

例如：

ALTER procedure [dbo].[IBS_PodiumSummeryCount] 
    @locid integer = null 
AS 
BEGIN 
    SELECT * FROM Customers WHERE Location = @Locid; 

    SELECT * FROM Suppliers WHERE Location = @Locid; 
END 

將返回兩個查詢的結果，單獨的結果集。
