Where We Stand

By now you've learned how to construct a basic SQL statement, pass it to your database with Perl, and receive the results. That's 90% of the ballgame. As we've noted several times, this article has focused on Microsoft Access, and there are a few -- very few -- different twists in using these techniques in a Unix environment. Next month we'll look at the popular Unix-friendly MySQL database.

You may have noticed that our examples have so far been oriented solely towards reading data from a database. This is probably the goal of most readers and is certainly the easiest and safest interaction. Sometimes, though, you might wish to use Perl to write data to a database, either adding new records or updating existing ones. Here things become slightly tricker, as we must be concerned with safety -- both security and data integrity -- a topic we'll focus on later in this series on using Perl with databases.
