我有一个32位应用程序，必须在使用64位版本MySQL的Windows x64服务器上运行。
我应该使用32位ODBC驱动程序还是64位ODBC驱动程序？
还是我也应该安装32位版本的MySQL？

由于您的应用程序是32位的，因此您需要安装32位SQL和ODBC驱动程序以确保兼容性。
我仍在搜索，稍后会编辑。

为解决此问题，请使用适当版本的ODBC管理员工具。如果您在64位操作系统上构建并运行32位应用程序，则必须使用%windir%\SysWOW64\odbcad32.exe中的ODBC管理员工具创建ODBC数据源。要指示DSN类型，可以将“_32”添加到32位用户DSN中，并将“_64”添加到64位用户DSN中。

如果您想要一个解决方法，您需要使用管理工具创建ODBC数据源。在同一链接中也有说明。

谢谢Justin！我确实能够安装32位ODBC并且我的应用程序运行良好。（正如你所写的，ODBC DSN显示在%windir%\SysWOW64\odbcad32.exe中）谢谢Stefano。 - Stefano

我能够
在Windows 64位上安装32位ODBC
使用32位ODBC“连接”64位MySQL在64位Windows操作系统（2008 R2）上运行我的应用程序（32位）
为了实现1），我必须修改提供的MySQL ODBC zip包中的install.bat，以考虑32位驱动程序必须安装在c:\windows\syswow64的事实。
