mysql无法连接到MS Access

Question

我正在尝试将数据库从Microsoft Access转移到MySQL（我正在使用MySQL工作台）。为此，我需要将MySQL连接到Access，但遇到一些问题。 我正在遵循以下准则： https://dev.mysql.com/doc/workbench/en/wb-migration-database-access.html 测试连接时，它显示以下错误消息：

Unhandled exception: grt.Dict key must be string. 

我检查了日志以获取更多信息，这就是我发现的内容：

似乎我需要对文件进行一些更改，但是我不知道该怎么做，也无法在线找到答案。

Answer 1

你好，这很晚了。对我有用的解决方案是确保在添加DSN（数据源名称）的过程中添加数据库（如ms访问文件中一样）

如果我的话不清楚，请看这张图片：

Answer 2

如果尝试使用较新的ODBC连接器从旧格式的数据库（Access <2010 .mdb文件）迁移数据，则会看到此错误。首先，先以较新的格式保存文件（.accdb，然后再次尝试迁移。
