Primary key from inserted row jdbc?

Question

Is there a cross database platform way to get the primary key of the record you have just inserted?

I noted that this answer says that you can get it by Calling

Answer 1

Just declare id column as id integer not NULL primary key auto_increment

after this execute this code

ResultSet ds=st.executeQuery("select * from user");
                while(ds.next())
                {

                 ds.last();
                System.out.println("please note down your registration id  which is "+ds.getInt("id"));
                }
                ds.close();

the above code will show you the current row's id

if you remove ds.last() than it will show all values of id column
