I am getting the pkgid which is unique from the other application and i am supposed to store it in my database.When the other application requests the info related to Pkgid, i need to send the information from my application. Do i need create the id as number for Primary key or can i use the same package id as primary key. Which is the best way to approach?
Table ---- Package ------- id number number pkg_id varchar2 50
You can use it. But remember that,primary keys are used for making relationship between two or more tables. If you want only uniquness,then you can also make unique key. As you may be aware,both theses keys have differences.
PK has to be unique and not null. But UK can be null.
