Is it possible using adapter mode to do adapter.fetchentity(2) using forreign key just like is possible using the self selfing mode.

Using dotnet2,adapter, llblgen v2.5

Your question is not clear, the tilte speaks about Update using a Unique column and the body speaks about fetching an entity using a FK.

Would you please describe your question in more details?

Sorry for my bad explanation.

When using the self-servicing mode you can fetch any entity using a unique index value.

e.g FetchUsingUCReseller as compared with FetchUsingPK

Can you do this is adapter mode. I have been using the Fetchentitycollection with a bucket expression to achieve what i could easily do in self-serving mode.

Hope this is clear!

Yes you can. The following example os copied from the manual:

DataAccessAdapter adapter = new DataAccessAdapter(); CustomerEntity customer = new CustomerEntity(); customer.CompanyName = "Chop-suey Chinese"; adapter.FetchEntityUsingUniqueConstraint(customer, customer.ConstructFilterForUCCompanyName());

thank you! Solution found!
