Question

这是获取列（tat_orig）值

的Excel公式

=IF((X3-W3)*24<=24,(X3-W3)*24,
     IF(AND(WEEKDAY(W3,2)<6,WEEKDAY(X3,2)<6), (NETWORKDAYS(W3,X3)-1+MOD(X3,1)-MOD(W3,1))*24,
     IF(OR(WEEKDAY(W3,2)>5,WEEKDAY(X3,2)>5),(NETWORKDAYS(W3,X3)*24))))

这是获取列（tat_orig）的值的SQL查询：

IF OBJECT_ID(N'DATEDIFFBIG', N'FN') IS NOT NULL
    DROP FUNCTION dbo.DATEDIFFBIG;
GO

CREATE FUNCTION DATEDIFFBIG(@d1 datetime, @d2 datetime)
RETURNS bigint
AS
BEGIN
    RETURN CONVERT(bigint, DATEDIFF(day, @d1, @d2)) * 86400000 -
       DATEDIFF(second, DATEADD(day, DATEDIFF(day, 0, @d1), 0), @d1) * 1000 +
        DATEDIFF(second, DATEADD(day, DATEDIFF(day, 0, @d2), 0), @d2) * 1000;
END
GO

--Network days shim
IF OBJECT_ID(N'NETWORKDAYS', N'FN') IS NOT NULL
    DROP FUNCTION dbo.NETWORKDAYS;
GO
CREATE FUNCTION dbo.NETWORKDAYS(@d1 datetime, @d2 datetime)
RETURNS int
AS
BEGIN
    DECLARE @w1 int = DATEPART(weekday, @d1);
    DECLARE @w2 int = DATEPART(weekday, @d1);
    DECLARE @dd float = FLOOR(dbo.DATEDIFFBIG(@d1, @d2) / 86400000.0);

    -- network days is based on a holidays table; I just added this date arbitrarily so that
    -- the results match what Excel says
    DECLARE @holidays TABLE(holiday datetime);
    INSERT INTO @holidays VALUES
        ('2016-06-15');

    RETURN (@dd + @w2 - @w1) / 7 * 5 +
            @w2 - @w1 + 1 +
            IIF(@w2 = 7, -1, 0) +
            IIF(@w1 = 1, -1, 0) +
            (SELECT COUNT(*) FROM @holidays WHERE @d1 <= holiday AND holiday < @d2);
END
GO

-- Turn around time shim
IF OBJECT_ID(N'TURNAROUND', N'FN') IS NOT NULL
    DROP FUNCTION dbo.TURNAROUND;
GO
CREATE FUNCTION dbo.TURNAROUND(@d1 datetime, @d2 datetime)
RETURNS float
AS
BEGIN
    DECLARE @w1 int = DATEPART(weekday, @d1);
    DECLARE @w2 int = DATEPART(weekday, @d1);
    DECLARE @nd int = dbo.NETWORKDAYS(@d1, @d2);

    DECLARE @hd float = dbo.DATEDIFFBIG(@d1, @d2) / 3600000.0;
    DECLARE @td float = dbo.DATEDIFFBIG(CAST(@d1 AS TIME), CAST(@d2 AS TIME)) / 86400000.0;

    RETURN (

    IIF(@hd <= 24.0,
        @hd,
        IIF(@w1 < 6 AND @w2 < 6,
            24 * (@nd - 1 + @td),
            IIF(@w2 > 5 OR @w1 > 5,
                24 * @nd, 0))));
END
GO

-- the data
DECLARE @items TABLE
(
 time_created datetime,
 time_responded datetime
);

INSERT INTO @items VALUES
('2016-06-10 15:42:00.000', '2016-06-15 03:03:00.000'),
('2016-06-15 01:28:00.000', '2016-06-15 03:03:00.000'),
('2016-06-14 07:46:00.000', '2016-06-15 03:03:00.000'),
('2016-07-04 05:35:25.000', '2016-07-04 19:05:48.000'),
('2016-07-04 04:56:09.000', '2016-07-04 18:29:28.000'),
('2016-07-04 09:15:33.000', '2016-07-04 22:08:43.000'),
('2016-07-04 08:44:24.000', '2016-07-04 21:40:57.000'),
('2016-07-04 07:14:51.000', '2016-07-04 21:39:24.000'),
('2015-07-04 07:14:51.000', '2016-07-04 21:39:24.000');

-- the results
SELECT  time_created, time_responded, dbo.TURNAROUND(time_created, time_responded) AS [TAT Orig] FROM @items;

现在我有列（Tat_final）的Excel公式，它只与公式中的（w3）单元格更改为（y3）相同，我可以在现有公式中替换它来计算{{1} }。

这是tat_final的Excel公式：

tat_final

我需要SQL查询来获取=IF((X3-Y3)*24<=24,(X3-Y3)*24, IF(AND(WEEKDAY(Y3,2)<6,WEEKDAY(X3,2)<6),(NETWORKDAYS(Y3,X3)-1+MOD(X3,1)-MOD(Y3,1))*24, IF(OR(WEEKDAY(Y3,2)>5,WEEKDAY(X3,2)>5),(NETWORKDAYS(Y3,X3)*24))))。我知道我可以通过上面的查询得到它。但我不知道在哪里可以改变（Y3）而不是（W3），因为Excel中的公式是相同的。

SQL查询根据excel公式更新列
