binding.pryでsql文を表示したい時のおまじない

binding.pryの中で

> ActiveRecord::Base.logger = Logger.new(STDOUT)
=> #<Logger:0x007f8664e4a740
 @default_formatter=#<Logger::Formatter:0x007f8664e4a718 @datetime_format=nil>,
 @formatter=nil,
 @level=0,
 @logdev=
  #<Logger::LogDevice:0x007f8664e4a6c8
   @dev=#<IO:<STDOUT>>,
   @filename=nil,
   @mutex=
    #<Logger::LogDevice::LogDeviceMutex:0x007f8664e4a6a0
     @mon_count=0,
     @mon_mutex=#<Mutex:0x007f8664e4a650>,
     @mon_owner=nil>,
   @shift_age=nil,
   @shift_size=nil>,
 @progname=nil>

すると

>  User.active.count
D, [2016-01-14T11:19:50.133183 #29031] DEBUG -- :   CACHE (0.0ms)  SELECT COUNT(*) FROM `users` WHERE `users`.`active_flag` = 1 AND `users`.`deleted_at` IS NULL AND (`users`.`global_user_id` IS NOT NULL)
