Re: writing a function to mimic mysql last_insert_id

well, I know that I will have only a single sequence that will generate the
primary key per table. So basically, this type of function, for me needs
only to return the value of the primary key.

I believe I mentioned in one of my posts the motivation behind not wanting
to use currval()...which was to trying to avoid having the developers make a
lot of sql revisions to their application.

Thanks-Beth
