when you ask, is this worth learning? Go find out what exactly is it that your trying to learn before asking..
if your learning programming, try a programming language..
if your learning Database, Generic SQL language is a good start, then go into the database specifics..
if your ambition only includes scripting, then may be VB is for you..
so find out what you want to do, then find out what you should learn..
just for the record, learning about computer tells us that you want to learn how to use windows.. If you just want to learn about computers, please master the basics before going into sql languages..
