Get a database handle
From ClassDBI
How do you get a $dbh from your CDBI object?
In your script:
my $dbi = $class->db_Main()
or in your class file
my $dbi = __PACKAGE__->db_Main()
Class::DBI inherits from Ima::DBI; Ima::DBI creates the "db_Main" method when Class::DBI::connection() calls Ima::DBI's set_db().
Since Class::DBI explicitly names the connection "Main", the method is called "db_Main".
