How to add Column that will only work with specific column

Hi i have problem as i have table with columns and my question is how to add new column called longitude and latitude but i want to show it only for one specific column for example: i want it to show for INT column called ID with INT called number 1, but instead of that when i do new column it applies the same value to number 1, and other numbers that i have. Any help? Thanks.

Probably I misunderstand the question. You mean you want to have an auto-incremented column?
