I am familiar with how to use DBI to do a complex query and multi-record prepare/execute/fetch sequence. What I would like to know is how to use it to do something very simple such as ask the database what it thinks is the current date.

The way I know how to do it at the moment is:

$sth = $dbh->prepare('select current_date()'); $sth->execute(); my ($current_date) = $sth->fetchrow_array(); $sth->finish();

Is there a function in DBI which would do the equivilant thing but like this:

    my $current_date = $dbh->THEFUNCTION('select current_date()');

Is there an existing function like THEFUNCTION above in DBI? If not, what is the closest you can come? Am I missing something?

Cheers. -Andrew
