为什么我在 insert into (MS Access 2013) 中不断收到语法错误

Question

我是 SQL 新手。 我想在不创建重复项的情况下向表格添加行，但我不断收到错误，我不知道为什么：

INSERT INTO [P ET FA] (id_danger, P, FA)
    (SELECT 
         measure.id_danger, SUM(mesure.valeur_mesure) AS P, SUM(mesure.Val) AS FA
     FROM mesure
     GROUP BY mesure.id_danger)
WHERE mesure.id_danger != [P ET FA].id_danger

Answer 1

我对 ACCESS 不是很熟悉，但您可以尝试：

INSERT INTO [P ET FA] (id_danger, P, FA)
SELECT measure.id_danger, SUM(mesure.valeur_mesure) AS P, SUM(mesure.Val) AS FA
FROM mesure
where mesure.id_danger not in (select id_danger FROM [P ET FA])
GROUP BY mesure.id_danger

Answer 2

INSERT INTO [P ET FA] (id_danger, P, FA)
   SELECT SRC.id_danger, 
          SUM(SRC.valeur_mesure) AS P, 
          SUM(SRC.val) AS FA 
     FROM mesure SRC
          LEFT JOIN [P ET FA] DEST
            ON SRC.id_danger = DEST.id_danger
     WHERE DEST.id_danger IS NULL
           GROUP BY SRC.id_danger

这将仅为那些尚未在目标表中的 id_danger 值插入值。
