What directory are you in when connecting to the sqlite3 database? What command are you using to connect to said database?

I changed the path to the database file like so: my $database = "/Users/collin/Db/code_review.db";

Then:

kryten:scripts collin$ pwd
/Users/collin/scripts

And to connect to the database via sqlite3:

kryten:scripts collin$ sqlite3 /Users/collin/Db/code_review.db
