MySQL ODBC 32对64位

Question

我有一个32位应用程序，必须使用64位版本的MySQL在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？
或者我也应该安装32位版本的MySQL吗？

Answer 1

您需要安装一个32位SQL和ODBC驱动程序，看看您的应用程序是如何处理32位的。 出于兼容性原因。

我还在搜索，会编辑。

若要解决此问题，请使用适当版本的ODBC Administrator工具。 如果在64位操作系统上构建然后将应用程序作为32位应用程序运行，则必须使用％windir％\\ SysWOW64 \\ odbcad32.exe中的ODBC管理器工具创建ODBC数据源。 要指示DSN的类型，可以将“_32”添加到32位用户DSN，将“_64”添加到64位用户DSN。

如果要使用变通方法，则需要使用找到的管理工具创建ODBC数据源。这也在同一链接中进行了说明。

%windir%\SysWOW64\odbcad32.exe

Answer 2

我本来可以

1. 在Windows 64位上安装ODBC 32位

2. 让我的应用程序（32位）运行良好的32位ODBC“对64位Windows操作系统上的64位MySQL（2008 R2）

要实现1）我必须修改随MySQL ODBC的zip包提供的install.bat，以考虑到必须在c:\\windows\\syswow64安装32位驱动程序的事实。
