Отличается при использовании NHibernate и Oracle

Question

Проблема приведения типов при сравнении NHibernate. Ошибка возникает при использовании динамического пользовательского привязки Telerik с использованием базы данных NHibernate и Oracle.

В этом классе реализуется пользовательский привязчик Telerik, который отлично работает с Entity Framework и MS SQL Server 2008 при использовании с ошибками базы данных NHibernate и Oracle, передает VARCHAR в NVARCHAR при этом в mapinga NHibernate NO Property, который определяет тип Oracle база данных.

public static class DynamicDataBinding 
    { 
     public static IQueryable<T> Binding<T>(this IQueryable<T> query, GridCommand cmd, out int total) 
     { 
      query = query.Filtering(cmd.FilterDescriptors); 
      total = query.Count(); 
      return query.Sorting(cmd.GroupDescriptors, cmd.SortDescriptors).Paging(cmd.Page, cmd.PageSize); 
     } 

     private static IQueryable<T> Filtering<T>(this IQueryable<T> query, IList<IFilterDescriptor> filters) 
     { 
      return filters.Any() ? query.Where(ExpressionBuilder.Expression<T>(filters)) : query; 
     } 

     private static IQueryable<T> Paging<T>(this IQueryable<T> query, int currentPage, int pageSize) 
     { 
      return ((pageSize > 0 && currentPage > 0) ? query.Skip((currentPage - 1) * pageSize) : query).Take(pageSize); 
     } 

     private static IQueryable<T> Sorting<T>(this IQueryable<T> query, IEnumerable<GroupDescriptor> groups, IEnumerable<SortDescriptor> sorts) 
     { 
      query = groups.Any() ? groups.Reverse().Aggregate(query, (cur, group) => cur.AddSortExp(group.SortDirection, group.Member)) : query; 
      return sorts.Any() ? sorts.Aggregate(query, (cur, sort) => cur.AddSortExp(sort.SortDirection, sort.Member)) : query; 
     } 

     private static IQueryable<T> AddSortExp<T>(this IQueryable<T> query, ListSortDirection sort, string member) 
     { 
      return (sort == ListSortDirection.Ascending) ? query.OrderBy(member) : query.OrderByDescending(member); 
     } 
    } 

Вот журнал ошибок, SQL, из которого выполняется Oracle!

Mapping связывание презентации следовал формат V_INDICATORS_HISTORY

SELECT 
    uis.id, 
    uis.indicator_id, 
    ins.device_id,

Помогите пожалуйста это очень срочно, кто должен знать, как решить эту проблему в NHibernate слепков.

Answer 1

отображение в VARCHAR является discussed here:

<property name="SomeName" /> 
    <column sql-type="varchar" /> 
</property>
