PUT Update

Options
Okay so fairly simple. I am using PUT to update records. 
I want to update only one or two fields of a table. But most of the table is tables references to other tables "integers". 
I can pass "" for a text record and not update its contents. 
But I cant for anything else. All records get set to 0. 

How do I ignore all the other records I don't want to update. 

Thank you all.
