Is possible to Reload object by PK?

Hi Linq2Db!

Is it possible to do the reload of the object by PK? Something like this db.Reload(obj);

Indeed, methods db.Update(obj), db.Delete(obj), db.InsertOrReplace(obj) automatically generates SQL with filter by PK. I need this for SQL select (automatically filter by PK).

I cannot use “Find” method extension, because I need to reload object in common code and the type of object is unknown.

Could you provide me, what the best way for implementing this (workaround)? Thank you in advance!

You can use FirstOrDefault. Yes ConfigurationID is hidden, if you have problem with finding better alternative I can look at. I think you’ve got an idea and can correct expression 😉 Usually I recommend this extension to analyze what is generated: ReadableExpressions

Hi @sdanyliv ! Many-many thanks for your help and the solution!!!

Your code works well! I would ask some clarifying questions…

The first question. My linq2db version (3.0.1) does not know dc.MappingSchema.ConfigurationID.

(I corrected this how I guess, but maybe you know how it will better…)

The second, when the select does not return the object, I got exception “Sequence contains no elements”. Probably this is Ok. Maybe the result of method Reload (true/false) also looks ok…

So, I can adapt this code. I just want to say many-many thanks! 😃 As for me, to have Reload in base functionality will be super!
