将存储过程插入临时表，临时表返回空

Question

由于我无法控制的原因，我必须一次查询一个设施 ID 的某些程序，这意味着我需要遍历所有设施并注入临时表才能有效地利用数据。

我已经多次使用这个循环并且从来没有遇到过问题。由于这个特定查询的某种原因，临时表返回空，我不知道为什么。

存储过程自行完美执行，整个查询运行时不会引发任何错误。但是，当我选择 * #HistoricalRentalActivity 时，我得到一个空白表（但标题正确）

IF OBJECT_ID('tempdb..#HistoricalRentalActivity') IS NOT NULL 
     DROP TABLE #HistoricalRentalActivity

IF OBJECT_ID('tempdb..#rowsiteHistoricalRentalActivity') IS NOT NULL 
     DROP TABLE #rowsiteHistoricalRentalActivity

SELECT 
    ROW_NUMBER() OVER (ORDER BY siteid) AS rownum, siteid 
INTO #rowsiteHistoricalRentalActivity 
FROM dbo.sites

CREATE TABLE #HistoricalRentalActivity
(
        SiteID INT,
        iSortOrder INT,
        sDescActivity VARCHAR (200),
        dcM1 MONEY,
        dcM2 MONEY,
        dcM3 MONEY,
        dcM4 MONEY,
        dcM5 MONEY,
        dcM6 MONEY,
        dcM7 MONEY,
        dcM8 MONEY,
        dcM9 MONEY,
        dcM10 MONEY,
        dcM11 MONEY,
        dcM12 MONEY,
        dcM13 MONEY,
        dcM14 MONEY,
        dc3MonthAvg MONEY
)


DECLARE @enddate datetime
SET @enddate = DATEADD(ss, -1, DATEADD(month, DATEDIFF(month, 0, getdate()), 0))

DECLARE @maxrow INT
SET @maxrow = (SELECT COUNT(siteid) FROM #HistoricalRentalActivity)

DECLARE @row INT
SET @row = 1

WHILE(@row <= @maxrow)
BEGIN
    DECLARE @siteidrow INT
    SET @siteidrow = (SELECT siteid FROM #rowsiteHistoricalRentalActivity WHERE rownum = @row)

    INSERT INTO #HistoricalRentalActivity (SiteID, iSortOrder, sDescActivity,
        dcM1, dcM2, dcM3, dcM4, dcM5, dcM6, dcM7, 
        dcM8, dcM9, dcM10, dcM11, dcM12, dcM13, dcM14, 
        dc3MonthAvg)
       EXEC dbo.spRptMgmtHistorytb
                @SiteID = @siteidrow,
                @dEnd = @enddate

    SET @row = @row + 1
END

我很茫然，希望其他人有想法？

Answer 1

maxRow 需要从 #rowSiteHistoricalRentalActivity 而不是您刚刚创建的表中获取计数。
