I have a Perl script that connects to a sqlite3 databaase and does a query. Example:

    #!/usr/software/bin/perl5.8.8

    use strict;
    use warnings;

    my $db = 'somedb';
    my $dbh = DBI->connect("dbi:SQLite:dbname=$db", "", "", {RaiseErro
+r => 1}) or die $DBI::errstr;
    # doing something here with $dbh...
    $dbh->disconnect;

The above code works, but I would like to add a condition when the DBI->connect fails. Currently the script dies, but instead I would like to have an if statement that does something alternative if the db I am connecting to is not available. Then exits. I was thinking of this:

    #!/usr/software/bin/perl5.8.8

    use strict;
    use warnings;

    my $db = 'somedb';
    my $dbh = DBI->connect("dbi:SQLite:dbname=$db", "", "", {RaiseErro
+r => 1});
    
    # Is this the right way to check if DBI connected to the database?
    unless ($dbh) {
        print "Unable to connect to $db.\n";
        # doing something else here...
    }
    # doing something here with $dbh...
    $dbh->disconnect;

Is this right? Thank you for the help.
