我在C ++中运行查询，但我无法正确处理日期。我希望约会以24小时的日期时间格式返回（年/月/日yhy：Hh24：mi：ss）。我在MS Access中运行查询，如下所示：
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;
哪个运行正常;但是当我在我的代码中运行它时，我收到以下错误：
System.IndexOutOfRangeException：日期/时间 在System.Data.ProviderBase.FieldNameLookUp.GetOrdinal（String fieldName）
at system.Data.Odbc.OdbcDataReader.GetOrdinal（String value）
at System.Data.Odbc.OdbcDataReader.get_Item（String value）
...在我的代码的第120行
代码有人帮助我理解这一点。这是我现在必须处理的代码的最后一个组件，我真的很想完成它，谢谢你的所有帮助。

答案 0 :(得分：0)
来自http://msdn.microsoft.com/en-us/library/90a7b8k5.aspx：
OdbcDataReader :: Item
的描述IndexOutOfRangeException : No column with the specified name was found.
显然，命名数据库表列时存在问题。
提示：尝试先按字段编号获取字段。然后尝试OdbcDataReader::GetName(number)获取列名称。
编辑：
dayTime = DbReader.GetString(0); // or
dayTime = DbReader.GetString("Date / Time");
对我来说似乎更具可读性。
