@id id data type: primitive or object which one is better?

[gus888]

Hi there,

I have a question about the primary key @id data type. Some use primitive, e.g. long and int, but some use object, e.g. Long and Integer. Which one is better or the two cases are the same. Thank you in advance.

No help?

i use primitives, seems to make the most sense (since its a primary key, its can't be nullable, so using larger Object representation doesn't seem necessary).

Some people don't like setting the primitive int to "0" to indicate the ID isn't set - if you are one of those people, use Integer so you can set it to null to indicate the primary key isn't set yet.
