Isn't NULL a macro in C for 0? So doesn't that mean these items are free?

Null is zero in german - so this must be free, it's a german shop

In a way it's still the same with more modern languages. Especially OOP, setting an object to Null is just setting the address pointer to to 0x00000000.

Hence NullPointerException / NullReferenceException or similar, depending on the language.

I'd guess, in context, it's a floating point price column that hasn't been set, and the table designer didn't specify the column to be NOT NULL.

I guess Rust would have solved the problem as well.
