Comment obtenir une liste des commandes par serveur et à la minute (serveur SQL)

[ad_1]

Bonjour-

J’essaie d’obtenir une liste des commandes passées sur chaque serveur à la minute près. Je peux l’obtenir avec un simple script mais je dois changer la clause WHERE pour chaque minute. J’espère trouver quelque chose qui puisse interroger la plage en une seule requête.

J’espère obtenir un résultat comme celui-ci….

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

Merci !!!

Ce que j’ai essayé :

C’est la requête qui fonctionne mais je dois changer la minute à chaque fois. Je dois changer le 09h40 en 09h41 puis 09h42, etc.

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

J’ai essayé cela mais cela prend incroyablement longtemps et je dois encore modifier les minutes si je veux interroger une plage différente.

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

Commencez par compter les commandes de chaque serveur pour chaque minute :

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
;

Si vous voulez vraiment une colonne pour chaque minute, vous devrez alors utiliser un PIVOT – cela nécessitera quand même d’ajouter une entrée pour chaque minute :

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
;

Si vous souhaitez éviter de saisir toutes les minutes, vous aurez besoin d’un pivot dynamique – par exemple :

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;
