在SP中选择多个返回一个记录集

Question

Im使用MS SQL，并有一段代码需要多个基本SP来运行我想要做的是将它们压缩到一个。

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 

我怎么能做到这一点，并返回它作为一个记录集即

驱动ID，JM ID，组ID，外部JM ID，进口额，停留时间，JM外部ID

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

Answer 1

假设他们每个只返回一行，你可以用CROSS JOIN来组合它们：

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; 

如果它们返回多个值，那么您需要解释如何将结果合并到一行中。
