Now that the basic syntax problem is solved, I can't resist harping on the old truism (which many have probably grown tired of seeing):

If you're processing a lot of rows, you'd be better off making you perl script a little simpler: have it just print out another suitable flat file that would be easy to feed into whatever data-importer tool is native to the particular database server you are using.

The speed differential between bulk-loading with such a tool vs. doing a series of inserts with DBI (even with a prepared statement and placeholders) can be dramatic if you're dealing with thousands of rows on a regular basis. And of course, you can set up your perl script so that once it's done writing the loadable flat file, it goes ahead and runs your database bulk-loader utility on the file. That way, the end result from the user's point of view is the same, except that it happens much faster.

(For smaller sets of rows, it's a toss-up -- whatever you're most comfortable with is fine -- but the bulk-load tool scales well, whereas DBI inserts do not.)
