Hi, Thanks for the info :-)
An expression which causes the exceptions is: var aisles = from aisle in SchemaModel.Aisle select aisle; Aisle table has this structure private string _aisleID; private decimal? _relationalXcOoRd; private decimal? _relationalYcOoRd; private string _tempRegime; Not srue if you need this but: The table itslef in Oracle has a Primary Key od AisleId which can't be null. It is indexed on aisle id. I hope this is what you were looking for. Let me know if you need anything else.
