我有一个旧的.mdb数据库，其中有许多表/表单/查询和外部连接（在Access 2003中创建），具有用户级安全性。
现在我已决定迁移到SQL Server，但我无法解密数据库（在Access 2010和2013中）以使用Access to SQL工具。
解密过程正在运行但最终我收到错误：“您无法访问此表”。
我试过修理＆amp;压缩。
你能帮助我吗？
谢谢。
答案 0 :(得分：0)
据我所知，你没有很多选择：
您可以通过创建新数据库并使用与原始用户完全相同的用户名和PID来重建.mdw文件，然后将新.mdw与旧数据库一起使用。 />
您可以使用the tools from Serge Gavrilov中的一些来帮助您从数据库中找到用户名和PID。
查看UtterAccess.com上的论坛。似乎有很多关于 lost mdw 的讨论。
您可以使用EverythingAccess之类的数据修复服务。花一些钱，但我相信他们可以恢复你的数据。
一旦您可以访问数据库，您就可以编写代码以从数据库中提取所有表单，查询等。这是我编写的代码片段。您需要大量调整它，因为它基于允许您选择数据库名称的表单。你将不得不为查询，表格等重复这个......
