New first time to NHibernate, used another tool for years though. Working
with already existing db design, that works with the other tool, getting
this error with NHibernate - DevArt EntityDesigner
Custom tool error: Invalid inheritance 'Company_Customer'. Base Class
Discriminator Value is not specified..
Single Table Inheritance:
I have an abstract Company base class, and an inherited concrete Customer
and Vendor Classes.
the discriminator is string "Customer", "Vendor" and I have no
discriminator on Company because it is abstract and should never be
created, and therefore there are only Vendors or Customers.
Our current ORM, when querying Companies, will generate
WHERE discriminator = "Customer" or discriminator = "Vendor"
So, how do I fix this error? If I put one in just to get rid of the error
e.g. "Company", then the generated SQL on a query for Companies would not
be as shown above would it? it would be WHERE discriminator = "Company"
which will always return 0 zero results .
How do I resolve this?
Thanks in advance
JAMES
