在SP中選擇多個返回一個記錄集

Question

Im使用MS SQL，並有一段代碼需要多個基本SP來運行我想要做的是將它們壓縮到一個。

ALTER PROCEDURE SP_JOB_IMPORT_MULTICALL 
(
@driverid as int, 
@vehicleid as int, 
@place as nvarchar(50) 
) 
AS 
DECLARE @imval as int 

BEGIN 
    SET @imval = (SELECT ad.ImportValue FROM Admin AS ad WHERE ad.ID=1) +1 
END 

BEGIN 
    SELECT DriverID,[JM ID] FROM Drivers WHERE DriverID=@driverid 
    SELECT [Unit ID],[External JM ID] FROM Vehicles WHERE [Unit ID] = @VehicleID 
    SELECT ImportValue FROM admin WHERE ID=1 
    SELECT Dwelltime FROM Places WHERE Placename = @place 
    SELECT [JM External ID] FROM Places WHERE Placename = @place 
END 
    UPDATE ADMIN SET ImportValue = @IMVAL WHERE ID=1 


    RETURN 

我怎麼能做到這一點，並返回它作爲一個記錄集即

驅動ID，JM ID，組ID，外部JM ID，進口額，停留時間，JM外部ID

1 ------------ 1 -------- 1 -------- 1 ----------------- --- 1 ----------------- 1 -------------- 1

Answer 1

假設他們每個只返回一行，你可以用CROSS JOIN來組合它們：

SELECT * 
FROM (SELECT [JM ID] FROM Drivers WHERE DriverID=@driverid) d CROSS JOIN 
    (SELECT [Unit ID],[External JM ID] FROM Vehicles WHERE [Unit ID] = @VehicleID) v CROSS JOIN 
    (SELECT ImportValue FROM admin WHERE ID=1) a CROSS JOIN 
    (SELECT Dwelltime FROM Places WHERE Placename = @place) p CROSS JOIN 
    (SELECT [JM External ID] FROM Places WHERE Placename = @place) p2; 

如果它們返回多個值，那麼您需要解釋如何將結果合併到一行中。
