Bagaimana cara mendapatkan daftar pesanan berdasarkan server dan per menit (SQL server)

[ad_1]

Halo-

Saya mencoba mendapatkan daftar pesanan yang datang dari setiap server setiap menitnya. Saya bisa mendapatkannya dengan skrip sederhana tetapi saya harus mengubah klausa WHERE untuk setiap menit. Saya berharap menemukan sesuatu yang dapat menanyakan rentang dalam satu permintaan.

Saya berharap mendapatkan hasil seperti ini….

SERVER	9:40	9:41	9:42	9:43	9:44	9:45
SV1	     9	     12	     7	     8	     1	     2
SV2	     16	     10	     8	     11	     18	     25
SV3	     27	     22	     29	     11	     4	     7
SV4	     22	     20	     22	     22	     47	     47

Terima kasih !!!

Apa yang saya coba:

Ini adalah kueri yang berfungsi tetapi saya harus mengubah menitnya setiap kali. Saya harus mengubah 09:40 menjadi 09:41 lalu 09:42, dst.

SQL

SELECT h.line AS 'SERVER'
,COUNT(DISTINCT c.id) AS '9:40'
FROM customer c 
INNER JOIN orders o 
	ON c.id = o.id
INNER JOIN handle h 
	ON c.line = h.line
WHERE c.datetime BETWEEN '2024-02-21 09:40:00.000' AND '2024-02-21 09:40:59.999'
GROUP BY h.line
ORDER BY  1

Saya telah mencoba ini tetapi memerlukan waktu yang sangat lama dan saya masih harus mengubah menitnya jika saya ingin menanyakan rentang yang berbeda.

SQL

SELECT h.line AS 'SERVER'

,(SELECT COUNT(DISTINCT c1.id) FROM customer c1 INNER JOIN orders o1 ON c1.id = o1.id INNER JOIN handle h1 ON c1.line = h1.line
WHERE h.line = h1.line
AND c1.datetime BETWEEN '2024-02-21 09:40:00.000' AND '2024-02-21 09:40:59.999') AS '9:40'

,(SELECT COUNT(DISTINCT c2.id) FROM customer c2 INNER JOIN orders o2 ON c2.id = o2.id INNER JOIN handle h2 ON c2.line = h2.line
WHERE h.line = h2.line
AND c2.datetime BETWEEN '2024-02-21 09:41:00.000' AND '2024-02-21 09:41:59.999') AS '9:41'

,(SELECT COUNT(DISTINCT c3.id) FROM customer c3 INNER JOIN orders o3 ON c3.id = o3.id INNER JOIN handle h3 ON c3.line = h3.line
WHERE h.line = h3.line
AND c3.datetime BETWEEN '2024-02-21 09:42:00.000' AND '2024-02-21 09:42:59.999') AS '9:42'

,(SELECT COUNT(DISTINCT c4.id) FROM customer c4 INNER JOIN orders o4 ON c4.id = o4.id INNER JOIN handle h4 ON c4.line = h4.line
WHERE h.line = h4.line
AND c4.datetime BETWEEN '2024-02-21 09:43:00.000' AND '2024-02-21 09:43:59.999') AS '9:43'

,(SELECT COUNT(DISTINCT c5.id) FROM customer c5 INNER JOIN orders o5 ON c5.id = o5.id INNER JOIN handle h5 ON c5.line = h5.line
WHERE h.line = h5.line
AND c5.datetime BETWEEN '2024-02-21 09:44:00.000' AND '2024-02-21 09:44:59.999') AS '9:44'

,(SELECT COUNT(DISTINCT c6.id) FROM customer c6 INNER JOIN orders o6 ON c6.id = o6.id INNER JOIN handle h6 ON c6.line = h6.line
WHERE h.line = h6.line
AND c6.datetime BETWEEN '2024-02-21 09:45:00.000' AND '2024-02-21 09:45:59.999') AS '9:45'

FROM customer c 
INNER JOIN orders o 
	ON c.id = o.id
INNER JOIN handle h 
	ON c.line = h.line
GROUP BY h.line
ORDER BY  1

Mulailah dengan menghitung pesanan untuk setiap server setiap menitnya:

SQL

DECLARE @day datetime = '2024-02-21';

SELECT
    c.line As SERVER,
    M.Minute,
    COUNT(DISTINCT c.id) As OrderCount
FROM
    customer c
    INNER JOIN orders o ON o.id = c.id
    INNER JOIN handle h ON h.line = c.line
    CROSS APPLY (SELECT FORMAT(c.datetime, 'HH:mm')) As M (Minute)
WHERE
    c.datetime >= @day And c.datetime < DateAdd(day, 1, @day)
GROUP BY
    c.line,
    M.Minute
ORDER BY
    c.line,
    M.Minute
;

Jika Anda benar-benar menginginkan kolom untuk setiap menit, Anda harus menggunakan a PIVOT – ini masih mengharuskan Anda menambahkan entri untuk setiap menit:

SQL

DECLARE @day datetime = '2024-02-21';

WITH cteSource As
(
    SELECT
        c.line As SERVER,
        M.Minute,
        COUNT(DISTINCT c.id) As OrderCount
    FROM
        customer c
        INNER JOIN orders o ON o.id = c.id
        INNER JOIN handle h ON h.line = c.line
        CROSS APPLY (SELECT FORMAT(c.datetime, 'HH:mm')) As M (Minute)
    WHERE
        c.datetime >= @day And c.datetime < DateAdd(day, 1, @day)
    GROUP BY
        c.line,
        M.Minute
)
SELECT
    SERVER,
    [09:40],
    [09:41],
    [09:42],
    [09:43],
    [09:44],
    [09:45]
FROM
    cteSource As S
    PIVOT
    (
        SUM(OrderCount)
        FOR Minute In ([09:40], [09:41], [09:42], [09:43], [09:44], [09:45])
    ) As P
ORDER BY
    SERVER
;

Jika Anda ingin menghindari mengetik seluruh menit, maka Anda memerlukan pivot dinamis – misalnya:

SQL

DECLARE @day datetime = '2024-02-21';
DECLARE @columns nvarchar(max);
DECLARE @sql nvarchar(max);

WITH cteHours As
(
	SELECT TOP 24 ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) - 1 As H
	FROM sys.all_columns
),
cteMinutes As
(
	SELECT TOP 60 ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) - 1 As M
	FROM sys.all_columns
)
SELECT 
	@columns = STUFF(
		(SELECT N', [' + FORMAT(H.H, '00') + N':' + FORMAT(M.M, '00') + N']'
		FROM cteHours H CROSS APPLY cteMinutes M 
		FOR XML PATH(''), TYPE).value('.', 'nvarchar(max)'), 
		1, 1, N'')
;

SET @sql = N'
WITH cteSource As
(
    SELECT
        c.line As SERVER,
        M.Minute,
        COUNT(DISTINCT c.id) As OrderCount
    FROM
        customer c
        INNER JOIN orders o ON o.id = c.id
        INNER JOIN handle h ON h.line = c.line
        CROSS APPLY (SELECT FORMAT(c.datetime, ''HH:mm'')) As M (Minute)
    WHERE
        c.datetime >= @day And c.datetime < DateAdd(day, 1, @day)
    GROUP BY
        c.line,
        M.Minute
)
SELECT
    SERVER, ' + @columns + N'
FROM
    cteSource As S
    PIVOT
    (
        SUM(OrderCount)
        FOR Minute In (' + @columns + N')
    ) As P
ORDER BY
    SERVER
;';

EXEC sp_executesql @sql, N'@day datetime', @day = @day;
