Question

我正在制作一个存储过程来了解应该安排维护的未来日期，但是桌子上有很多机器但是程序只调用一个。

我使用的声明是为了调用每台机器的数据并进行循环以了解给定范围内的未来日期

@name varchar(50),
                @FechaHasta datetime,
                @Result     DATETIME = null OUTPUT)
AS

BEGIN

DECLARE @JOBNO NVARCHAR(50)
    SELECT  @JOBNO = JOBNO FROM PMMASTER INNER JOIN LABORMP 
    ON PMMASTER.PMID = LABORMP.PMID INNER JOIN PMMSCHEDULE
    ON PMMASTER.PMID = PMMSCHEDULE.PMID 
    where EMPLOYEENAME = @name AND PMMSCHEDULE.CYCLETYPE =2 and PMMSCHEDULE.SETTING2 IS NOT NULL and PMMSCHEDULE.SETTING1 IS NOT NULL

    DECLARE @DATELAST DATETIME
        SELECT @DATELAST = DATELAST FROM PMMSCHEDULE INNER JOIN PMMASTER
        ON PMMASTER.PMID = PMMSCHEDULE.PMID INNER JOIN LABORMP
        ON PMMASTER.PMID = LABORMP.PMID 
        WHERE JOBNO in (@JOBNO) and EMPLOYEENAME =@name 

    DECLARE @SETTING1 INT
        SELECT @SETTING1 = SETTING1 FROM PMMSCHEDULE INNER JOIN PMMASTER
        ON PMMASTER.PMID = PMMSCHEDULE.PMID INNER JOIN LABORMP
        ON PMMASTER.PMID = LABORMP.PMID 
        WHERE JOBNO in (@JOBNO)  AND EMPLOYEENAME = @name 

        DECLARE @SETTING2 INT
        SELECT @SETTING2 = SETTING2 FROM PMMSCHEDULE INNER JOIN PMMASTER
        ON PMMASTER.PMID = PMMSCHEDULE.PMID INNER JOIN LABORMP
        ON PMMASTER.PMID = LABORMP.PMID 
        WHERE JOBNO in (@JOBNO)  AND EMPLOYEENAME = @name 

DECLARE
    @DateFirst  INT
SELECT  @DateFirst  =   @@DateFirst

/* Today */ 
DECLARE 
        @TodaysDate     DATETIME    
-- Finding today's date after resetting the time to midnight 
SELECT  @TodaysDate = CONVERT(DATETIME, CONVERT(VARCHAR, GETDATE(), 101), 101)

SELECT  @WeekDay    =   CHARINDEX('1',  @Setting2) 

/* Schedule Date */ 
DECLARE
        @ScheduleDate   DATETIME 
-- Find the starting schedule date. If the schedule date is in a previous  
-- week, adjust to the most recent week in the schedule 
SELECT  @ScheduleDate   =   @DATELAST 

-- Adjust scheduled date to closest possible week day
SELECT  @ScheduleDate = DATEADD(dd, @WeekDay - DATEPART(dw, @ScheduleDate), @ScheduleDate)

-- Add cycles until a possible date is met  
WHILE   (@ScheduleDate  <   @TodaysDate)
    SELECT  @ScheduleDate   =   DATEADD(wk, @Setting1, @ScheduleDate)

IF  (@ScheduleDate  <=  @DATELAST)
    SELECT  @ScheduleDate   =   DATEADD(wk, @Setting1, @ScheduleDate)

SELECT  @Result =   @ScheduleDate

SELECT @Result AS RESULTADO

SET DATEFIRST   @DateFirst


WHILE(@Result <@FechaHasta)
    BEGIN
        IF(@Result <@FechaHasta)

            SELECT  @Result =   DATEADD(WK, @Setting1,  @Result)
            SET IDENTITY_INSERT [00TblFecha] ON 

            INSERT INTO dbo.[00TblFecha](idFecha,jobno,fecha)VALUES(3,@JOBNO,@Result)

            SET IDENTITY_INSERT[00TblFecha] OFF     
            print @Result
        end

您有几个选项：
- 使用表值参数，这是首选：（https://msdn.microsoft.com/en-us/library/bb510489.aspx）
- 使用XML参数
- 使用逗号分隔列表。
- 循环遍历所有“机器”

顺便说一句，在SP中排除使用@@ DateFirst。无论如何你不使用它。

如何使参数在存储过程中读取多个值？
