Question

使用ODBC适配器时出现此错误。可能是我的版本不匹配？看起来我正在使用activerecord-odbc-adapter-2.0和activerecord-3.1.0。

以下是我的代码中失败的行：

states_controller.rb：

class StatesController < Controller

def update()    
    ...
        Web::State.transaction do #<-- this is line 12

            nti_states.each do |state| #<-- line 15
                ...

（这只是一个红宝石应用程序。不是rails）如果您需要更多信息，请告诉我。

是的，这是一个宝石兼容性问题。从2011年的ActiveRecord 3.1.0开始，select_all采用第三个参数（不可否认最新的）ODBC 2.0适配器不支持，因为它可以追溯到2008年。有关相关的Informix适配器问题，请参阅https://github.com/santana/activerecord-informix-adapter/issues/4

很难相信没有人提供更新的ODBC适配器，也许更难以相信没有人以SO可见的方式抱怨这一点，但也许就是这种情况。哦，强大的力量如何下降。 ; - ）
