Re: accesse Call parameters in ONError?

Do you mean TRestServer.OnUriError?

If the exception is raised during the parsing, or there is no parameter, it is nil.
You should be able to use Ctxt.Call^.Uri instead.

All this is as intended.

But anyway, the error is to be caught with a try..finally in your own method code.
No in OnErrorUri callback.

Note: you can get the DB error from GetDbError() function of mormot.db.core.pas.

True, but I wanted to raise errors in different places in the application if possible and handle them in only one place. This way, I would avoid writing hundreds of try excepts and centralize all error handling in one place.

I am afraid it may lead to a confusion between logic error and database error.

As a better alternative, you may encapsulate the SQL execution into some methods of your own, with a centralized error handling.

Re: accesse Call parameters in ONError?

I created a custom exception class containing error codes and messages for handling business errors. However, one limitation I'm facing is that I cannot access URI parameters in this scenario.
