每N条记录的总和SQL

Question

我有这个查询，它返回（紧接在“查询结果”下面）一个分组的日期（varchar）和一些值。 它们是经过收费广场的车辆。

SELECT SUBSTR(CAB_MOMENTO,1,12),
Sum(CASE WHEN COMVSAUTO = '1' AND NOME IN ('SUL','OESTE') THEN 1 ELSE 0 END) 
SUL_OESTE_AUTO,
Sum(CASE WHEN COMVSAUTO = '0' AND NOME IN ('SUL','OESTE') THEN 1 ELSE 0 END) 
SUL_OESTE_COM,
Sum(CASE WHEN COMVSAUTO = '1' AND NOME IN ('NORTE','LESTE') THEN 1 ELSE 0 
END) NORTE_LESTE_AUTO,
Sum(CASE WHEN COMVSAUTO = '0' AND NOME IN ('NORTE','LESTE') THEN 1 ELSE 0 
END) NORTE_LESTE_COM FROM
(SELECT a.idtransaccion, a.cab_momento, a.cab_via, a.comvsauto, b.NOME
FROM
(select idtransaccion, cab_momento, cab_via, cab_estacion AS ESTACION,
CASE ctl_clase
WHEN '01' THEN 1
WHEN '07' THEN 1
WHEN '08' THEN 1
ELSE 0
END comvsauto
FROM usrhost.atransaccion
WHERE cab_momento > '20170818000000') a
INNER join
(SELECT sen.estacion AS ESTACION, via.via AS VIA, sen.nome AS NOME FROM 
usrhost.aestacion_sentido sen
INNER JOIN usrhost.avia via ON
sen.estacion = via.estacion
AND SubStr(via.via,3,1) = sen.sentido
ORDER BY 1,2) b ON
b.VIA = a.cab_via
AND b.ESTACION = a.ESTACION)
GROUP BY SUBSTR(CAB_MOMENTO,1,12)
ORDER BY 1

我每15分钟需要一笔款项（第一列）。

例如：从分钟X到分钟Y-1231 | 12314 | 1241 | 21415从分钟X + 15到分钟Y + 15-1111 | 13344 | 1345 | 22455 ...

先感谢您

Answer 1

您可以使用下面的表达式为您提供一个日期时间，并将分钟数调整为四分之一小时。 这使您能够轻松地将时间和日期分组。

CONVERT(datetime, LEFT(CONVERT(varchar(30), cab_momento, 126), 14) + RIGHT('0' + CONVERT(varchar(2), DATEPART(MINUTE, cab_momento) / 15 * 15), 2) + ':00.000', 126)

解决它！ 非常感谢你。
