Sql server 返回具有负等效项的行

我有一个包含多个列的非规范化表。我想返回所有具有相同值的正数和负数的列

例如：

ID  |  Value
-------------
1   |  10
1   | -10
3   |  15
3   |  15
4   | -1
5   |  4

电流输出：

ID | Values
-------------
1  |  10
1  | -10
3  |  15
3  |  15

期望输出：

ID | Value
-------------
1 |  10
1 | -10

我制作了一个windows函数，如下所示，它将选择相同的绝对值，但这包括有正数的对

select Count(*) Over (Partition By DVN, [Tran Date], [Reference Number],Description,Vendor, Abs([Maintenance Expense])) As cnt , * 
    From WorkTemp.dbo.Customer2700Combine
    Where [Maintenance Expense] Is Not Null
Order By 1 Desc,DVN, [Tran Date], [Reference Number],Description,Vendor, Abs([NonRental Total])

不确定您的需求是否由[ID]确定，请查看您的示例、描述和所需输出，我将这样做：

DROP TABLE IF EXISTS #sopg;

SELECT [ID],
       [VALUE]
INTO #sopg
FROM
(
    SELECT 1 AS ID,
           10 AS VALUE
    UNION
    SELECT 1 AS ID,
           -10 AS VALUE
    UNION
    SELECT 3 AS ID,
           15 AS VALUE
    UNION
    SELECT 3 AS ID,
           15 AS VALUE
    UNION
    SELECT 4 AS ID,
           -1 AS VALUE
    UNION
    SELECT 5 AS ID,
           4 AS VALUE
) x;

-- Assuming that one ID can only have maximum 2 rows (like your example above) and want this by ID

SELECT s.[ID],
       s.[VALUE]
FROM #sopg s
    INNER JOIN
        (
        SELECT ID,
               SUM(VALUE) SumZero
        FROM #sopg
        GROUP BY ID
        HAVING SUM(VALUE) = 0
    ) SumZero ON SumZero.ID = s.ID

  -- Another way, assuming that ID can have more than 2 rows and different values

DROP TABLE IF EXISTS #sopg2;

SELECT [ID],
       [VALUE]
INTO #sopg2
FROM
(
    SELECT 1 AS ID,
           10 AS VALUE
    UNION
    SELECT 1 AS ID,
           -10 AS VALUE
    UNION
        SELECT 1 AS ID,
           -9 AS VALUE
    UNION
    SELECT 3 AS ID,
           15 AS VALUE
    UNION
    SELECT 3 AS ID,
           15 AS VALUE
    UNION
    SELECT 4 AS ID,
           -1 AS VALUE
    UNION
    SELECT 5 AS ID,
           4 AS VALUE
) x

SELECT a.[ID],
       a.[VALUE]
FROM #sopg2 a
INNER JOIN #sopg b ON b.ID = a.ID AND a.VALUE = -b.VALUE

大家好，欢迎来到SO。是一个很好的起点。在上面的示例中，您是否关心这些值是同一ID的一部分？或任何值，无论ID如何？非常感谢！第二个解决方案非常有效，匹配反向值非常聪明，我不知道你能做到！是的，你基本上可以在“=”部分做每一个转换，顺便说一句，如果你复制并粘贴我在我的答案中的测试数据，作为你问题中输入测试数据的一部分，人们可能会对你的答案进行投票，因为这样更容易理解和复制。干杯
