I have entity that is a subtype. How can I retrieve source table name at run time? GetFieldPersistenceInfos() returns empty array. I see generated code calling this.AddElementMapping() on the entity that is a subtype, I just don't know how to get to the table name. I'm using version 3.1.

Thank you.

From your previous posts I assume you are using Adapter. So create a new DataAccessAdapter partial class in your DBSpecific generated project and follow this code http://www.llblgen.com/TinyForum/Messages.aspx?ThreadID=20908&StartAtMessage=0&#117843

Yes, I am using Adapter and I've tried the method described in the forum below. It works for entities that are not derived from other entities. However, for subtype entities in TargetPerEntityHierarchy GetFieldPersistenceInfos() returns an empty array. Would I need to check if entity has supertype and pass the supertype to GetFieldPersistenceInfos()? What's the proper way to get the supertype's typename at runtime?

Thanks.

Which runtime library version (build no.) are you using?

I am using 3.1.11.907

Could you please try the latest release of v.3.1 And you may also try that of v.3.5

Tried latest 3.1 build 3.1.12.1015. Same problem. GetFieldPersistenceInfos() returns empty array. If I pass the superttype entity name, it works fine. Also works fine if entity is not subtyped.

Is there's a way to get the name of supertype name given entity name?

I think the code mentioned in the above referenced thread might be a downside when using it in a subtype. Please try this:

public partial class DataAccessAdapter
{
    public string GetTableName(IEntity2 entity)
    {
        return this.GetFieldPersistenceInfos(entity)[0].SourceObjectName;
    }
}

... at least it works here. If you still have problems please describe your inheritance hierarchy and what are the real tables behind them.

(Edit) Above code will fail if you use Inheritance per Entity Hierarchy with no additional fields on subtype. You better use something like thing:

return this.GetFieldPersistenceInfo(entity.PrimaryKeyFields[0]).SourceObjectName;
