我有一个MS Access数据库，有10多个查询，需要每周更新。将每一个单独导出，然后将每个单独上载到我服务器上的SQL，这真是一件痛苦的事情

我已尝试将Access数据库直接连接到SQL server，但由于安全原因，我的服务器不允许这样做

我发现了一个模块，它将在一个文件中打印查询，但它只打印标题，这是有用的，但不完全是我要找的

以下是模块代码：


公共子迭代器DefsCollection（）



Dim dbMain作为DAO.Database



将qdf设置为DAO.QueryDef

作为DAO.QueryDef的Dim qdfTemp



设置dbMain=CurrentDb



对于dbMain.querydfs中的每个qdf

Debug.Print qdf.Name'打印查询的名称

设置qdfTemp=dbMain.querydfs（qdf.Name）

Debug.Print qdfTemp.SQL'打印查询的SQL语法

下一步



端接头
我不写这些代码，而且对SQL还是相当陌生的，所以我的问题是……有没有办法将我所有的查询及其数据导出到.SQL文件中

提前感谢。

您的SQL server的身份验证过程不“知道”谁或什么应用程序正在尝试连接到它。如果您提供了有效的凭据，那么它应该接受连接尝试。正常连接到SQL Server时，您提供什么类型的凭据？（工作时）在指定Access尝试连接的凭据时使用相同的凭据，并且Access连接也将工作。如果在access中创建了链接表，access应要求您指定这些连接凭据。一旦您有了一个连接到sql server的有效链接表，您就可以对sql server表运行Access查询（使用Access链接表作为指针）

我不明白您为什么要每周更新10个查询。在我看来，这些应该是参数驱动的，等等。请注意，下面并不是在移动数据。在我看来，代码中的一些追加查询应该可以很好地处理这个问题

下面是我编写的一个模块，试图将Access MDB中的所有查询升级到服务器。请注意，由于其中一些查询是“堆叠的”，即它们称为其他查询，因此必须运行此子例程数次，直到它无法再升迁
