我正在尝试使用 gem dbi 或 sqlanywhere gem 来访问 Windows 64 位机器上的 SQLAnywhere 12 数据库。数据库在本地运行。我完全没有成功，任何帮助将不胜感激。

使用 DBI 时

require 'rubygems' 
require 'dbi' 

DBI.connect('DBI:ODBC:Agency')

返回

使用 sqlanywhere 时

require 'sqlanywhere' 

api = SQLAnywhere::SQLAnywhereInterface.new() 
SQLAnywhere::API.sqlany_initialize_interface( api ) 
api.sqlany_init()

sqlanywhere gem 已解决此问题。我一直无法成功使用 dbi。

基本上我运行的是 Ruby 的 32 位版本，并且在以下文件夹结构中没有 dbcapi.dll - C:\Program Files\SQL Anywhere 12\Bin32. 我有另一台测试机器（32 位）SQL Anywhere，我在 64 位测试机器上复制了 dbcapi.dll。我的路已经定好了。

总而言之 - 在运行 ruby​​ 1.9.3p385 (2013-02-06) [i386-mingw32] 以使用 sqlanywhere gem (sqlanywhere-0.1.6-x86-mingw32) 时，请确保以下几点：

dbcapi.dll 存在于以下文件夹结构中 -C:Program Files\SQL Anywhere 12\Bin32 确保您的路径包括C:\Program Files\SQL Anywhere 12\Bin32
