mysql - MySQL ODBC 32 与 64 位

Question

我有一个 32 位应用程序，它必须在使用 64 位版本的 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？

Answer 1

您需要安装 32 位 SQL 和 ODBC 驱动程序，以了解您的应用程序是 32 位的。出于兼容性原因。

我还在寻找，将编辑。

要变通解决此问题，请使用适当版本的 ODBC 管理器工具。如果在 64 位操作系统上构建并运行应用程序作为 32 位应用程序，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，可以在 32 位用户 DSN 中添加“_32”，在 64 位用户 DSN 中添加“_64”。

如果您想要一个解决方法，您需要使用 Admin 工具创建您的 ODBC 数据源。这也在同一链接中进行了说明。

%windir%\SysWOW64\odbcad32.exe

Answer 2

我以前可以

1. 在 Windows 64 位上安装 ODBC 32 位

2. 让我的应用程序（32 位）在 64 位 Windows 操作系统（2008 R2）上使用 32 位 ODBC“对抗”64 位 MySQL 运行良好

为了实现 1) 我不得不修改 MySQL ODBC 的 zip 包中提供的 install.bat 以考虑到 32 位驱动程序必须安装在c:\windows\syswow64.
