Re: [GENERAL] using ID as a key

Hi David,

I like your example below since it is simple enough for
someone who is new to this to implement, but I'm wondering
how the IDs are maintained ? Will it be auto incremented
this way ? Or would I need to write a function to do that ?
Would I be able to view the ID numbers ? I guess since you've
declared it as an integer it is readable by humans.
I want this ID to act like a social insurance number but it
will not be seen or used by anyone except the developer (me).
My database is going to be fairly small ( very unlikely to
ever exceed more than 2000 records ).
