SQL commands are relatively universal, whether you're using Access or MySQL or Postgresql. "SELECT database_name" will give you a table of all the fields and values within that database. The entire SQL command library is available on line; however, if you're using the VB tools inside Access, you don't really need to know SQL per se. I'd go through the Access help files first, to get a list of all the queries you're likely to need.
Hope this helps
