如何按 id 列更正组 - sql

Question

我有这个问题：

SELECT TwI_TwIId,
       TwI_TwrId,
       TwI_MagId,
       SUM(TwI_Ilosc) AS Ilosc,
       SUM(TwI_Wartosc) AS Wartosc,
       SUM(TwI_Braki) AS Braki,
       SUM(TwI_Rezerwacje) AS Rezerwacje,
       SUM(TwI_Zamowienia) AS Zamowienia
FROM cdn.TwrIlosci
WHERE twi_magid = 1
GROUP BY TwI_TwrId,
         TwI_TwIId,
         TwI_MagId
ORDER BY TwI_TwIId;

我不知道为什么，但是这个查询不能缩放重复 TwI_TwrId。

我有这个结果：

Answer 1

因为 TwI_TwrId 每个都有唯一的 TwI_TwIId，你需要从 group by 子句中排除它们：

SELECT TwI_TwrId, TwI_MagId,
       SUM(TwI_Ilosc) AS Ilosc,
       SUM(TwI_Wartosc) AS Wartosc,
       SUM(TwI_Braki) AS Braki,
       SUM(TwI_Rezerwacje) AS Rezerwacje,
       SUM(TwI_Zamowienia) AS Zamowienia
FROM cdn.TwrIlosci
WHERE twi_magid = 1
GROUP BY TwI_TwrId, TwI_MagId;

Answer 2

您的语句给出了 TwI_TwrId、TwI_TwIId、TwI_MagId 三列的不同组合，如果您想删除 TwI_TwrId 的重复项，则运行下面那个

SELECT 
       TwI_TwrId,
       TwI_MagId,
       SUM(TwI_Ilosc) AS Ilosc,
       SUM(TwI_Wartosc) AS Wartosc,
       SUM(TwI_Braki) AS Braki,
       SUM(TwI_Rezerwacje) AS Rezerwacje,
       SUM(TwI_Zamowienia) AS Zamowienia
FROM cdn.TwrIlosci
WHERE twi_magid = 1
GROUP BY TwI_TwrId,
         TwI_MagId
