Now, save this file, then make a copy for yourself, for when you wish to create a another new database, for example: $ cp numismatist.sql skeleton.sql So, break out your favorite text editor and edit numismatist.sql to contain the following (if you don’t have an editor, yet, then keep reading, and you’ll soon be able to finish anyway): /* We are going to begin with a text file representation, and build from there. There are many ways to begin using SQLite. Of course, you are welcome and encouraged to change things, as you work with the examples. The database will be called numismatist.db, and the schema table will be coins. exit.įor the examples we will assume an arbitrary person, in this case, a numismatist (coin-collector).
