If ID column is primary key and auto increment as you said, it cant be equal
to zero.
You got a query which reads:
UPDATE columns WHERE false
There is no chance for any updates.

Yikes! Then how do I update this table? I will need to update every variable
*except* the ID, which is the primary key and an auto_increment.
