hi!
when i want to create a table that its goal is to connect between objects, do i need to create it with primary key?
for example, i saw here:
http://www.vaannila.com/hibernate/hiber ... any-3.html

that the STUDENT_PHONE table doesn't have a primary key.

what is the best way to use? with primary key or without?

Dont create table manually by using the query in your database.
When you use this

in your hibernate configuration file, it will automatically create the table.
However, If you use this
in your id tag it will automatically creates that field with primary key.
native denotes database handling the primary key generation.

In future dont give any public forum link here for your reference.
If you want to know something post your queries exactly what you want?
No one go and see the link and suggest the solution.
Use CODE TAG wisely
