Other solution is to check for conflicts before issuing tableUpdate()
What I do know is to try tableUpdate(). If it returns .F., then I check for errors (uniqueness of primary key violated, trigger failed, conflicts, ...)

What I can do know is to call the conflict checking function before tableUpdate(). I don't like this solution, but I think it will work.

I wonder if many programmers rely on checking "primary key only" in the views, and try to check for conflicts after calling tableUpdate(). I think this does not work OK, as in this case tableUpdate() will not return .f. if there is any conflict in any field that is not the primary key field.

Thanks for your help,
Javier.

However, I will not insist that strict normalization is desirable or practical in all cases. It is convenient in most cases, but I myself have used exceptions in some cases.
