24選擇查詢的數據格式

我在C++中運行查詢，但無法正確處理日期。我想約會以24小時日期時間格式返回（dd/mm/yyyy Hh24：mi：ss）。我已經在MS Access中運行查詢，如下所示：24選擇查詢的數據格式

SELECT Format(Data.[Date/Time],'mm/dd/yyyy hh:nn:ss'), DATA.[Hot Strip Mill Total], DATA.[Basic Oxygen Furnace Total], DATA.[Electro-Arc Furnace Total], DATA.[J-9 Shop Total], DATA.[Levy Maintence Building Total], DATA.[Ford Body Shop Total], DATA.[Ford Chiller Building Total], DATA.[Ford Dearborn W Plant Total], DATA.[Ford Dearborn E Plant Total], DATA.[Ford Dearborn Balcony Total], DATA.[Ford Final Assembly Total], DATA.[Ford Frame Plant Total], DATA.[Ford Dearborn N Plant Total], DATA.[Ford Tool and Die Total], DATA.[Ford Paint Plant Total], DATA.[Ford Glass Plant Total], DATA.[Hot Strip Mill Rate], DATA.[Basic Oxygen Furnace Rate], DATA.[Electro-Arc Furnace Rate], DATA.[J-9 Shop Rate], DATA.[Levy Maintence Building Rate], DATA.[Ford Body Shop Rate], DATA.[Ford Chiller Building Rate], DATA.[Ford Dearborn W Plant Rate], DATA.[Ford Dearborn E Plant Rate], DATA.[Ford Dearborn Balcony Rate], DATA.[Ford Final Assembly Rate], DATA.[Ford Frame Plant Rate], DATA.[Ford Dearborn N Plant Rate], DATA.[Ford Tool and Die Rate], DATA.[Ford Paint Plant Rate], DATA.[Ford Glass Plant Rate] 
FROM DATA;

它運行良好;然而，當我在我的代碼運行此我得到以下錯誤：

System.IndexOutOfRangeException：日期/時間 在System.Data.ProviderBase.FieldNameLookUp.GetOrdinal（字符串字段名）

在system.Data.Odbc .OdbcDataReader.GetOrdinal（字符串值）

在System.Data.Odbc.OdbcDataReader.get_Item（字符串值）

...在我的代碼120線

代碼有人幫我意義這個的。這是我現在必須處理的代碼的最後一個組件，我真的很樂意完成它，謝謝你的幫助。

我只是想補充一點，我沒有創建Access表，所以我不負責列名的可怕格式。 –

+0

正確的標籤？代碼看起來更像C＃。 –

+0

日期格式是一個表示層的問題，你不應該擔心你的SQL。 –

從http://msdn.microsoft.com/en-us/library/90a7b8k5.aspx：

OdbcDataReader說明::項目

IndexOutOfRangeException : No column with the specified name was found.

顯然，在命名數據庫表列的問題。

提示：嘗試先按字段號獲取字段。然後嘗試OdbcDataReader::GetName(number)以獲取列名稱。

編輯：

dayTime = DbReader.GetString(0); // or 
dayTime = DbReader.GetString("Date/Time");

似乎更具可讀性給我。

我不認爲有一個名稱BC的問題我添加了以下行： 控制檯.WriteLine（DbReader [「Date/time」]。ToString（））; afterdaytime = DbReader [「Date/time」]。ToString（））; –

@Dante：是的，但是您不應該從'DbReader [...]'中的方括號中得到一個IndexOutOfRangeException，這表示沒有從列名稱字符串到從零開始的列號的映射。現在你用'Date/time'而不是'Date/Time''？也許SQL不區分大小寫，但C＃是。 –

+0

我不認爲名稱BC有問題我添加了以下行： Console.WriteLine（DbReader [「Date/time」]。ToString（））; daytime = DbReader [「Date/time」]。ToString（））; 然後當我在該行後面運行程序時，我收到了其給定格式的數據。我仍然需要 這種格式的數據：「2011/7/1 16:01:07」而不是「07/1/2011 4:01:07 PM」 –
