这就是我一直在做的，如果你需要做一些迭代…但首先寻找集合操作是明智的。另外，不要这样做，因为您不想学习游标。

select top 1000 TableID
into #ControlTable 
from dbo.table
where StatusID = 7

declare @TableID int

while exists (select * from #ControlTable)
begin

    select top 1 @TableID = TableID
    from #ControlTable
    order by TableID asc

    -- Do something with your TableID

    delete #ControlTable
    where TableID = @TableID

end

drop table #ControlTable

对sam yi的答案做个小改动(为了更好的可读性):

select top 1000 TableID
into #ControlTable 
from dbo.table
where StatusID = 7

declare @TableID int

while exists (select * from #ControlTable)
begin

    select @TableID = (select top 1 TableID
                       from #ControlTable
                       order by TableID asc)

    -- Do something with your TableID

    delete #ControlTable
    where TableID = @TableID

end

drop table #ControlTable

如果您喜欢使用临时表，这是另一种方法。我亲自测试了这个，它不会导致任何异常(即使临时表没有任何数据)。

CREATE TABLE #TempTable
(
    ROWID int identity(1,1) primary key,
    HIERARCHY_ID_TO_UPDATE int,
)

--create some testing data
--INSERT INTO #TempTable VALUES(1)
--INSERT INTO #TempTable VALUES(2)
--INSERT INTO #TempTable VALUES(4)
--INSERT INTO #TempTable VALUES(6)
--INSERT INTO #TempTable VALUES(8)

DECLARE @MAXID INT, @Counter INT

SET @COUNTER = 1
SELECT @MAXID = COUNT(*) FROM #TempTable

WHILE (@COUNTER <= @MAXID)
BEGIN
    --DO THE PROCESSING HERE 
    SELECT @HIERARCHY_ID_TO_UPDATE = PT.HIERARCHY_ID_TO_UPDATE
    FROM #TempTable AS PT
    WHERE ROWID = @COUNTER

    SET @COUNTER = @COUNTER + 1
END


IF (OBJECT_ID('tempdb..#TempTable') IS NOT NULL)
BEGIN
    DROP TABLE #TempTable
END

您可以选择对数据进行排序，并添加一个ROW_NUMBER，并在迭代数据集时倒数至零。

-- Get your dataset and rank your dataset by adding a new row_number
SELECT  TOP 1000 A.*, ROW_NUMBER() OVER(ORDER BY A.ID DESC) AS ROW
INTO #TEMPTABLE 
FROM DBO.TABLE AS A
WHERE STATUSID = 7;

--Find the highest number to start with
DECLARE @COUNTER INT = (SELECT MAX(ROW) FROM #TEMPTABLE);
DECLARE @ROW INT;

-- Loop true your data until you hit 0
WHILE (@COUNTER != 0)
BEGIN

    SELECT @ROW = ROW
    FROM #TEMPTABLE
    WHERE ROW = @COUNTER
    ORDER BY ROW DESC

    --DO SOMTHING COOL  

    -- SET your counter to -1
    SET @COUNTER = @ROW -1
END

DROP TABLE #TEMPTABLE

这样我们就可以迭代到表数据。

DECLARE @_MinJobID INT
DECLARE @_MaxJobID INT
CREATE  TABLE #Temp (JobID INT)

INSERT INTO #Temp SELECT * FROM DBO.STRINGTOTABLE(@JobID,',')
SELECT @_MinJID = MIN(JobID),@_MaxJID = MAX(JobID)  FROM #Temp

    WHILE @_MinJID <= @_MaxJID
    BEGIN

        INSERT INTO Mytable        
        (        
            JobID,        
        )        

        VALUES        
        (        
            @_MinJobID,        
        ) 

        SET @_MinJID = @_MinJID + 1;
    END

DROP TABLE #Temp

STRINGTOTABLE是用户定义函数，它将解析逗号分隔的数据并返回表。谢谢
