Question

我遇到了Sequel连接到MS SQL数据库的问题。我安装了以下内容：

的unixODBC
freetds的

我已经配置了两个软件包，以下命令允许我连接到我的数据库而没有问题：

ISQL
TSQL
OSQL

但是，当我使用Sequel.odbc命令从Ruby代码尝试它时，我收到以下错误：

ODBC ::错误：IM003（0）[iODBC] [驱动程序管理器]无法加载指定的驱动程序。

这是我能得到的。我曾经先收到另一个错误，但设法通过重做配置部分来解决这个问题。猜猜我错过了什么。

修改

这是我的基础讲话者课程的代码。它基本上像rails一样加载一个YAML文件，保存数据库设置并建立与数据库的连接。这似乎有效，尝试手动从续集中返回一个DB对象：

module Talkers
  require 'yaml'
  require 'sequel'

  class BaseTalker
    # This function will load the desired settings as a hash from the database.yml file
    # in the config folder. The data will be returned as a hash following the standard
    # YAML structure.
    def self.load_config(name)
      cfg = YAML::load(File.open(File.join(ENV['API_ROOT'], 'config', 'database.yml')))
      cfg.key?(name) ? cfg[name] : nil
    end

    # This function will establish a connection with the Florensia User database and return
    # the Sequel database object, so that queries can be executed against the database.
    def self.connect_to_user_db
      settings = self.load_config("florensia_user_#{ENV['RACK_ENV']}")
      Sequel.odbc settings['dsn'], :db_type => settings['adapter'], :user => settings['user'], :password => settings['password']
    end
  end
end

下面的类继承自讲话者并为用户执行某些操作。它包含特定于游戏的DB逻辑。当我调用这个逻辑时，我收到错误：

module Talkers
  require 'yaml'
  require 'sequel'

  class LoginDbTalker < BaseTalker
    #
    # Bans the specified User from the game. The function requires the following information
    # to be supplied in order for the ban to be properly set:
    # - id : The identifier of the account.
    # - gm_name : The name of the GM setting the ban.
    # - punish_code : The punishment code being applied on the account.
    # - days : The duration of the ban in days, starting from today.
    #
    # The function will return true if the ban has been properly set; otherwise the function
    # will return false.
    def self.ban_user(options = {})
      return false if options.empty?
      db = self.connect_to_user_db
      ds = db[:tbl_User].filter(:id => options[:id])
      ps = ds.prepare(:update, :apply_ban)
      ps.call(
          :punishcode => options[:punish_code],
          :punishstory => "Banned by #{options[:gm_name]}",
          :punishdate => Date.today,
          :punishfreedate => (options[:days].to_i == -1) ? (Date.today + (30 * 265)) : (Date.today + options[:days].to_i))
      true
    rescue Exception => e
      puts "Exception caught in ban_user: #{e.to_s}"
      puts "Provided variables: id=#{options[:id]}, gm_name=#{options[:gm_name]}, punish_code=#{options[:punish_code]}, days=#{options[:days]}"
      false
    end
    #
    # Unbans the specified User from the game. The function requires the following information
    # to be supplied in order for the ban to be properly lifted:
    # - id : The identifier of the account.
    # - gm_name : The name of the GM removing the ban.
    #
    # The function will return true if the ban has been properly lifted; otherwise the function
    # will return false.
    def self.unban_user(options = {})
      db = self.connect_to_user_db
      ds = db[:tbl_User].filter(:id => options[:id])
      ps = ds.prepare(:update, :lift_ban)
      ps.call(
          :punishcode => '0',
          :punishstory => "Ban removed by #{options[:gm_name]}",
          :punishdate => Date.today,
          :punishfreedate => Date.today
      )
      true
    rescue Exception => e
      puts "Exception caught in unban_user: #{e.to_s}"
      puts "Provided variables: id=#{options[:id]}, gm_name=#{options[:gm_name]}"
      false
    end
    #
    # Kicks the specified User from the game, regardless on the server or character he currently is on.
    # This requires a direct connection to the game servers so a specialized command can be sent that
    # instruct the server to close the connection with the offending player.
    # The function returns true if the kick succeeded; otherwise false.
    def self.kick_player(id)
      false
    end
  end
end

调用任何禁止/取消功能会导致错误消息。

EDIT2

我添加了文件夹/ Library / ODBC，并将所有配置文件链接到iODBC。这消除了我以前的错误，现在给我带来了这个错误：

ODBC ::错误：01000（20002）[FreeTDS] [SQL Server] Adaptive Server连接失败

所以我似乎再次取得了一些进展

Answer 1

如果您从OS X连接到Microsoft SQL Server，我建议您使用tinytds适配器而不是odbc适配器。我知道有些人在非Windows机器上运行Sequel / ODBC，但我只有经验在Windows上使用Sequel / ODBC。

Mac Lion上的ODBC与Ruby Sequel
