SQL SUM 有條件/列名“SUM”無效

Question

我試圖在某些條件下對變量 value/valeur 求和，但我收到此錯誤：無效的列名“SUM”。

SELECT SUM[value/valeur] 
FROM [dbo].[tmp_norm_can]
WHERE [state/etat] = '1000' 
  AND [geo/geo] = '1' 
  AND [country/pays] != '999'

我附上了數據庫的圖像

非常感謝！

在此處輸入圖像描述

Answer 1

sum是 function。 嘗試

SELECT SUM([value/valeur])
FROM [dbo].[tmp_norm_can]
WHERE [state/etat] = '1000' 
  AND [geo/geo] = '1'
  AND [country/pays] != '999'

Answer 2

嘗試使用不同於“SUM”的名稱為您的列起別名。

Answer 3

謝謝！

有效的代碼是： SELECT SUM(CAST([value/valeur] AS NUMERIC)) AS "TOTAL", [year/annee] FROM [dbo].[tmp_norm_can] WHERE [state/etat] = '1000' AND [geo/geo] = '1' AND [country/pays] != '999'
