Hello,

I am using the DBI module to enable me to use a PostgreSQL database in several Perl programs. My programs have several Perl source files drawing common data from a package file.

In the package file, let's say MyPackage.pm, I get a database hadler for use inside the package, $dbh, by issuing $dbh = DBI->connect(...). I also have an exported function in MyPackage.pm called getDbRef() which returns a reference to $dbh.

When my source code files need to use the database, to execute an INSERT statement for example, sometimes they call an exported function from MyPackage.pm (which in turn would call $dbh->do($sql) or something) and sometimes they use the exported reference directly ($$dbh->do($sql) or something).

My question: is one of my methods better than the other? If so, why?

Thanks,

fx
