Bulk upserts via a primary key

Hello everyone!
I'm trying to add an insert record function to my app in more than one table. I'm working with a relational database and some inputs from the user, so I was looking for an insert function using the PK. I found the "Bulk upserts via a primary key", but it doesn't seem to be available anymore.
Is there any other way to do this?

Why is it no longer available?
