使用包含 SUM() 字段的子查询在 MS-Access 中编辑查询

Question

当我在 Access 中打开此查询（它只是 2 个链接表的集合）时，我可以毫无问题地编辑数据。

SELECT O.*, PP.skuapexid
FROM tblSkuBestellingen AS O
INNER JOIN tblSkuApex AS PP
ON (PP.begindatum <= O.besteldatum) AND (PP.sku = O.sku)
WHERE NOT EXISTS
   (
      SELECT * FROM tblSkuApex PP2
      WHERE PP2.sku = PP.sku AND
      PP2.begindatum <= O.besteldatum AND
      PP2.begindatum > PP.begindatum
   );

但是，当我添加一个小字段来显示已交付产品的总数时，它突然不允许我再编辑它了。有没有办法解决这个问题？

SELECT O.*, PP.skuapexid,
   (
        SELECT Sum(Nz(tblLeveringProduct.geleverd,0)) AS TotaalGeleverd
        FROM tblSkuBestellingen LEFT JOIN tblLeveringProduct ON tblSkuBestellingen.SkuBestelId=tblLeveringProduct.SkuBestelId
        WHERE  tblSkuBestellingen.sku = PP.sku
    ) AS TotaalGeleverd
FROM tblSkuBestellingen AS O
INNER JOIN tblSkuApex AS PP
ON (PP.begindatum <= O.besteldatum) AND (PP.sku = O.sku)
WHERE NOT EXISTS
   (
      SELECT * FROM tblSkuApex PP2
      WHERE PP2.sku = PP.sku AND
      PP2.begindatum <= O.besteldatum AND
      PP2.begindatum > PP.begindatum
   );

Answer 1

如果查询或任何连接查询中有任何聚合（Grouy by、Sum、Count、...），则您无法编辑数据。

你可以写一个函数来计算表中每一行的总和。
