Hello, I have the following mapping... public SalesMap ( ) { this.Table ( "sales" );
this.LazyLoad ( ); this.Id ( x => x.SalesNo ).GeneratedBy.Identity ( ).Column ( "sales_no" ); this.References ( x => x.MasterSalesNo ).Column ( "master_sales_no" ); this.Map ( x => x.Record ).Column ( "record" ).Not.Nullable ( ).Not.Insert ( ).Not.Update ( ).Generated.Always ( ); this.Map ( x => x.Timestamp ).Column ( "timestamp" ).Not.Nullable ( ).Not.Insert ( ).Not.Update().Generated.Always() ; this.Map ( x => x.CreatedBy ).Column ( "created_by" ).Not.Nullable ( ).Length ( 8 ).CustomSqlType ( "varchar(8)" ); this.Map ( x => x.CreateTime ).Column ( "create_time" ).Not.Nullable ( ); this.Map ( x => x.UpdatedBy ).Column ( "updated_by" ).Not.Nullable ( ).Length ( 8 ); this.Map ( x => x.UpdateTime ).Column ( "update_time" ).Not.Nullable ( ); this.Map ( x => x.EntryDate ).Column ( "entry_date" ).Not.Nullable ( ); this.Map ( x => x.OrderSts ).Column ( "order_sts" ).Not.Nullable ( ).Length ( 2 ); this.Map ( x => x.PrevOrderSts ).Column ( "prev_order_sts" ).Not.Nullable ( ).Length ( 2 ); this.Map ( x => x.FixedRateFlag ).Column ( "fixed_rate_flag" ).Not.Nullable ( ); this.Map ( x => x.RequestTime ).Column ( "request_time" ); this.Map ( x => x.BillOnShipFlag ).Column ( "bill_on_ship_flag" ).Not.Nullable ( ); this.Map ( x => x.CustomerPoNo ).Column ( "customer_po_no" ).Not.Nullable ( ).Length ( 30 ); this.Map ( x => x.Document ).Column ( "document" ).Not.Nullable ( ).Length ( 20 ); this.Map ( x => x.UserDefined1 ).Column ( "user_def1" ).Not.Nullable ( ).Length ( 40 ); this.Map ( x => x.UserDefined2 ).Column ( "user_def2" ).Not.Nullable ( ).Length ( 40 ); this.Map ( x => x.UserDefined3 ).Column ( "user_def3" ).Not.Nullable ( ).Length ( 40 ); this.HasMany ( x => x.SalesSet ).KeyColumn ( "master_sales_no" ); } when it saves it to the database, i get the following error...
