Answer 1

好的，你还没有澄清你的需求，所以我在这里走出困境。我提供的不仅仅是一个答案，而是鼓励你澄清你的问题。附件可能就是你想要的......但如果没有，这似乎很有可能，它应该让你更好地了解你真正需要提出的问题：

WITH MySplit AS
(
    SELECT
        128 as CurrentValue,
        50 as MaxPartition

    UNION ALL

    SELECT
        CurrentValue - MaxPartition,
        MaxPartition
    FROM
        MySplit
    WHERE
        CurrentValue - MaxPartition > 0
)

SELECT
    CASE
        WHEN MaxPartition < CurrentValue then MaxPartition
        ELSE CurrentValue
    END AS Partitition
FROM
    MySplit

替代：

假设某个表中的值为128（或其他），并且您希望将包含128的行拆分为包含50,50和28的三行（通常为50的分区加上最后一个的余数））：

DECLARE @rows_to_split AS TABLE (my_number INT)
INSERT INTO @rows_to_split VALUES (128),(204),(96)

--Everyone should have a "numbers" table, you may need additional rows.
--Search SO for how to generate them efficiently.
DECLARE @numbers AS TABLE (num int)
INSERT INTO @numbers VALUES (1),(2),(3),(4),(5),(6),(7),(8),(9),(10)

SELECT
    r.my_number,
    n.num,
    CASE WHEN n.num* 50 > r.my_number THEN (r.my_number - (n.num-1)*50) ELSE 50 END AS split
FROM
    @rows_to_split r
    JOIN @numbers n ON
        (n.num-1)*50 < r.my_number
ORDER BY
    r.my_number,
    n.num

----我已经用另一种方式看了我的代码。假设我有两个数字来分割。我们可以不使用循环来实现它

DECLARE @COUNT INT; DECLARE @ITEMCOUNT INT;

DECLARE @ShipTable table(
ID INT IDENTITY(1,1),
WbDItemNo char(15),
Qty int 


)
INSERT INTO @ShipTable
VALUES
(
'TEST ITEM',
59

),('TEST ITEM 1',225)

SELECT * FROM @ShipTable

SET @COUNT=(SELECT COUNT(*) FROM @ShipTable)
DECLARE @TOTALQTY INT 
DECLARE @UPAMOUNT INT
DECLARE @DIVISIONALVAL INT
DECLARE @DIVIDEBY INT
DECLARE @ITEM VARCHAR(50)
SET @DIVIDEBY=50;


DECLARE @ITEMNO VARCHAR(50)
WHILE(@COUNT>0)
BEGIN

  SET @TOTALQTY=(SELECT Qty FROM @ShipTable WHERE ID=@COUNT)
  SET @ITEM=(SELECT WbDItemNo FROM @ShipTable WHERE ID=@COUNT)


  SET @UPAMOUNT=@TOTALQTY%@DIVIDEBY
  SELECT @ITEM,@UPAMOUNT
  SET @DIVISIONALVAL=@TOTALQTY/@DIVIDEBY
  SET @DIVISIONALVAL=FLOOR(@DIVISIONALVAL)

  WHILE(@DIVISIONALVAL>0)
  BEGIN 
  SELECT @ITEM,@DIVIDEBY
  SET @DIVISIONALVAL=@DIVISIONALVAL-1
  END


  SET @COUNT=@COUNT-1
END

在SQL Server中将三行中的总值除以128
