Question

我有一个Access IC，我用Excel连接到VBA *

我有一个更新查询（在vba中），用户可以转到已下订单，并更新订单必须继续的路线。它有多个标准。

每个条件都有一个外键，可以从Int Id字段中获取值，但用户会选择description中String的条件。

这意味着在我可以执行更新查询之前，首先必须获取字符串条件的所有ID，因为外键字段采用ID（Int）而不是描述（String）。但是现在我试图在一次传递中完成所有操作，并使用嵌套在其中的select查询进行更新查询。

以下查询不起作用，并提供错误Operation must use an update-able query

updateOrdersRoute = "UPDATE tbl_orders " & _
    "SET tbl_orders.route = (SELECT tbl_deliveryRoutes.ID FROM tbl_deliveryRoutes WHERE tbl_deliveryRoutes.routes = '" & routeNameNew & "') " & _
    "WHERE ([tbl_orders.route] = (SELECT [tbl_deliveryRoutes.ID] FROM [tbl_deliveryRoutes] WHERE [tbl_deliveryRoutes.routes] = '" & routeNameOld & "') " & _
    "AND [tbl_orders.weekNo] = " & weekNo & " " & _
    "AND [tbl_orders.loadingDay] = (SELECT [tbl_weekday.ID] FROM [tbl_weekday] WHERE [tbl_weekday.weekDay] = '" & weekday & "') " & _
    "AND [tbl_orders.CustomerName] = '" & shopName & "')"

但以下查询确实有效:(仅更改了第二行）

updateOrdersRoute = "UPDATE tbl_orders " & _
    "SET tbl_orders.route = " & routeNumberNew & " " & _
    "WHERE ([tbl_orders.route] = (SELECT [tbl_deliveryRoutes.ID] FROM [tbl_deliveryRoutes] WHERE [tbl_deliveryRoutes.routes] = '" & routeNameOld & "') " & _
    "AND [tbl_orders.weekNo] = " & weekNo & " " & _
    "AND [tbl_orders.loadingDay] = (SELECT [tbl_weekday.ID] FROM [tbl_weekday] WHERE [tbl_weekday.weekDay] = '" & weekday & "') " & _
    "AND [tbl_orders.CustomerName] = '" & shopName & "')"

但是我必须首先使用额外的查询获取路径ID号，所以问题似乎是在查询的开头，但我无法弄清楚在哪里 - 或者是否有任何方式它将会工作。我确实尝试了this和其他解决方案，但它们似乎没有接近我想做的事情。

使用嵌套在其中的多个选择查询更新查询
