我有一个抛出异常的简单查询（见下文）。

• myTable* 表具有类型为Time的列，nHibernate尝试通过Int64将该列转换为TimeSpan。

我看到在使用Map时有TimeAsTimeSpan约定。
但我没有任何Map。
那么，不使用Map如何实现呢？

我的代码

string sqlText = "Select * from myTable";

        ISQLQuery query = Session.CreateSQLQuery(sqlText);

        query.List(); // <-- fails with exception

引发了异常

NHibernate.Exceptions.GenericADOException: could not execute query
