Question

我有两个表，我需要比较它的id并且只对具有相似id的行求和。因此，我需要显示日期，ID，总和（对于每个id）

我目前的代码是

Select a.OraReg,
       a.IdMezzo ,
       b.OraReg, 
       b.IdMezzo, 
       SUM(Saliti) over() as totalCount
from FLASH_STORICO.dbo.D_MSG_CONTAPASS as a
  inner join FLASH_STORICO.dbo.D_MSG_BORDO as b 
     on a.IdMezzo =b.IdMezzo 
    and a.OraReg = b.OraReg 
where a.OraReg > DATEADD(hour, -1, SYSDATETIMEOFFSET())
order by a.IdMezzo

我的当前结果显示每个ID的相同金额，

我做错了什么？

Answer 1

试试这个，

   SELECT a.OraReg
    ,a.IdMezzo
    ,SUM(Saliti) AS SumOfSaliti
FROM FLASH_STORICO.dbo.D_MSG_CONTAPASS a
INNER JOIN FLASH_STORICO.dbo.D_MSG_BORDO b ON a.IdMezzo = b.IdMezzo
    AND a.OraReg = b.OraReg
WHERE
    AND a.OraReg > DATEADD(hour, - 1, SYSDATETIMEOFFSET())
GROUP BY a.OraReg
    ,a.IdMezzo
ORDER BY a.IdMezzo

Answer 2

尝试

SELECT a.OraReg ,a.IdMezzo  ,b.OraReg   ,b.IdMezzo  ,SUM(Saliti) AS totalCount
FROM FLASH_STORICO.dbo.D_MSG_CONTAPASS AS a
JOIN FLASH_STORICO.dbo.D_MSG_BORDO AS b ON a.IdMezzo = b.IdMezzo AND a.OraReg = b.OraReg
WHERE a.OraReg > DATEADD(hour, - 1, SYSDATETIMEOFFSET())
GROUP BY a.OraReg,a.IdMezzo,b.OraReg,b.IdMezzo
ORDER BY a.IdMezzo

如果这不起作用，请遵循@GuidoG建议。

Sum列仅从最后一小时2 id等于
