在EF编程中我们能够通过lamda表达式能够进行查询数据。获取到IQueryable<T>结果，我们要想知道详细的SQL语句是什么须要使用ObjectQuery<T>进行处理

处理方法例如以下:

            IQueryable<Data> data = this.ObjectContext.Data.Where(d => d.Name.StartsWith("測试"));

            ObjectQuery<Data> oq=data as ObjectQuery<Data>;

            String sql=oq.ToTraceString();

执行结果例如以下:

SELECT

[Extent1].[ID] AS [ID],

[Extent1].[Name] AS [Name]

FROM (SELECT

      [Data].[ID] AS [ID],

      [Data].[Name] AS [Name]

      FROM [dbo].[Data] AS [Data]) AS [Extent1]

WHERE [Extent1].[Name] LIKE '測试%'
