У меня есть 3 таблицы, и мне нужно выбрать несколько записей, В двух таблицах из них у меня есть поля с одинаковыми именами, и когда я пытаюсь использовать Where Expression для этих полей, я получаю сообщение об ошибке: Если я использую TABLENAMe.Columns.COLNAME, это сообщение об ошибке показывает: Неоднозначное имя столбца 'FKLoginID'. и если я использую TableNAme.COLColumn.QualifiedName, он имеет ошибку рядом с созданным параметром "@ [dbo]. [Tbl_PersonalInformation]. [FKLoginID] 0"

Как я могу запросить эти таблицы? Спасибо 

 SqlQuery q = new Select().From(Tables.TblStockbrokerBroadDirector)
               .InnerJoin(TblPersonalInformation.PersonalInfoIDColumn, TblStockbrokerBroadDirector.FKPersonalInfoIDColumn)
               .InnerJoin(TblCompanyInformation.BizInfoIDColumn, TblStockbrokerBroadDirector.FKBizInfoIDColumn)
               .Where(TblPersonalInformation.FKLoginIDColumn.QualifiedName).IsEqualTo(User.Identity.Name);

Изменение 

.Where(TblPersonalInformation.FKLoginIDColumn.QualifiedName).IsEqualTo(User.Identity.Name);

до 

.Where(TblPersonalInformation.FKLoginIDColumn).IsEqualTo(User.Identity.Name);

Когда вы вызываете .QualifiedName, вы случайно вызываете Где (строка columnName) вместо Где (столбец TableColumn).

Вы можете убедиться в этом, проверив значение q.BuildSqlStatement (). Это очень полезно для отладки.

Должно работать следующее: 

SqlQuery query = DB.Select().From(Tables.TblStockbrokerBroadDirector)  
  .InnerJoin(TblPersonalInformation)  
  .InnerJoin(TblCompanyInformation)  
  .Where(TblPersonalInformation.Columns.FKLoginIDColumn).IsEqualTo(User.Identity.Name);
...
