I'm having trouble mapping the following setup in FNH. Any help would
be appreciated.
/***** Classes for Item Hierarchy *****/
public class ItemA
{
public string AProperty { get; set; }
}
public class ItemB : ItemA
{
public string BProperty { get; set; }
}
public class ItemC : ItemB
{
public string CProperty { get; set; }
}
public class ItemD : ItemB
{
public string DProperty { get; set; }
}
/***** Tables for Item Hierarchy *****/
TABLE A (ItemID INT, ItemTypeID INT, AProperty VARCHAR(100))
TABLE A (ItemID INT, ItemTypeID INT, BProperty VARCHAR(100))
TABLE A (ItemID INT, ItemTypeID INT, CProperty VARCHAR(100))
TABLE A (ItemID INT, ItemTypeID INT, DProperty VARCHAR(100))
/***** ItemTypeID to Class *****/
ItemTypeID = 1 --> ItemA
ItemTypeID = 2 --> ItemB
ItemTypeID = 3 --> ItemC
ItemTypeID = 4 --> ItemD
ItemTypeID = 5 --> ItemD
/***** ItemTypeID to Table *****/
ItemTypeID = 1 --> Data is in Table A
ItemTypeID = 2 --> Data is in Table A Join B
ItemTypeID = 3 --> Data is in Table A Join B Join C
ItemTypeID = 4 --> Data is in Table A Join B Join D
ItemTypeID = 5 --> Data is in Table A Join B Join D
I would like to use a Discriminator column (ItemTypeID) but the
SubClassMap<ItemD> would have to accept either a value of 4 or 5. Is
this possible?
