紅寶石不會產生異常的3

我同意按下列紅寶石不會產生異常的3

$: << File.expand_path(File.dirname(__FILE__) + "/../../config") 
$: << File.expand_path(File.dirname(__FILE__) + "/../../lib") 

require 'activerecord-sqlserver-adapter' 
require 'sa.gw.library' 
require 'sa.gw.lib.connection_manager' 

#connecting to sqlserver test 
@app_config = YAML.load_file("#{File.dirname(__FILE__)}/../../config/sa.gw.c.victim.yml") 
connection_manager = ConnectionManager.new(@app_config["tpaldb"]) #H 

begin 
    sql = "exec spTPal_Vic_GetDeviceStateByIMEI '000000000000000'" 
    result = connection_manager.execute_sproc(sql) 
      result.each {|r| 

      puts 'hello'   
      }    
    connection_manager.connection.close() 
    rescue => e 
     puts "An error occurred detail: #{e.message}" 

    end

我執行使用的Aptana Studio的3.這個程序這個簡單的代碼還算什麼我有經驗的是，如果存儲過程不讓用戶知道，那麼函數會自動終止。我想要一個機制是知道過程不存在於表單消息或異常中。

堆棧跟蹤是在以下

如果該過程不存在，應該提出什麼樣的錯誤？你沒有拯救任何東西，所以它不知道你想要拯救什麼。 '救援例外=>電子'應該讓你開始。但是你可能不想拯救那個特定的（所有的父母）異常。找到一個最接近應該獲救的東西。 – vgoff

奇怪！當我調試Sql Server類中的代碼時，它顯示了我的錯誤。當我調試它並逐步完成代碼時，它會靜靜地終止，當我運行應用程序時，它又向我顯示了錯誤。 –

你應該顯示堆棧跟蹤，然後解釋你的問題。 – vgoff

在Ruby中，默認救出例外將是StandardError。您在這裏顯示的內容並不顯示出現了什麼錯誤，或者可能是從SQL而不是從Ruby提出的。

然後，您正在挽救StandardError，因爲您沒有指定要嘗試解救的異常，而且確實可能是錯誤的。
