How can I concatenate two strings into one using LLBLGen Pro

Question

As the error says, I think LLBLGen have their own custom functions but official documentation doesn't help much. Is there any way to concatenate these two strings and make into one while LINQ querying?

   var viewModelCarrierDivisionQuery = from division in database.CarrierDivision
                                                    where division.CarrierId == carrierId
                                                    join carrier in database.Carrier
                                                    on division.CarrierId equals carrier.CarrierId
                                                    select new CarrierDetailViewModel.DivisionModel {
                                                        Id = division.CarrierDivisionId, 
                                                        Name = string.Join(" / ", carrier.Name, division.DivisionName)
                                                    };

SD.LLBLGen.Pro.ORMSupportClasses.ORMQueryConstructionException: 'Method call to 'Join' doesn't have a known mapped database function or other known handler.' 

Answer 1

What I have used is just a simple solution with plus name +" / "+name. This works. Is there any better way out there?
