如何使參數在存儲過程中讀取多個值？

-5

我正在製作一個存儲過程來了解將要安排維護的未來日期，但桌面上有很多機器，但過程僅調用一個。如何使參數在存儲過程中讀取多個值？

的聲明，我使用的是它來調用每臺機器的數據並做週期要知道在給定的

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

DECLARE @JOBNO NVARCHAR(50) 
    SELECT @JOBNO = JOBNO FROM PMMASTER INNER JOIN LABORMP 
    ON PMMASTER.PMID = LABORMP.PMID INNER JOIN PMMSCHEDULE

    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

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

因此，您發佈了一段包含while循環的文本。這裏真的有問題嗎？如果是這樣，你需要解釋你在問什麼。作爲一個方面說明，沒有理由需要使用這樣的插入while循環。 –

對不起，我的問題是如何讓存儲過程使用多臺機器來實現循環？ –

這沒有任何意義。請記住，我們不知道你的系統，我們不知道你的項目是什麼，我們看不到你的屏幕。我們需要處理的是對這個問題的非常模糊的描述。 –

範圍未來一段時間內，您有幾種選擇：
- 使用表值參數（https://msdn.microsoft.com/en-us/library/bb510489.aspx）
- 使用XML參數
- 使用逗號分隔列表。
- 循環遍歷所有「機器」

順便說一句，排除SP中@@ DateFirst的使用。無論如何，你不使用它。
