I got this code from Paul, the author of Perl and MySQL for the web...
I did scan the DBI module documentation, and do see the finish calls are different than what I do...
However, I am not reading from the database while it is connected, I store the data in a hashref:
$sth = $dbh->prepare(qq{select * from `table`});
$sth->execute();
my $_somevar = $sth->fetchrow_hashref();
$sth->finish();
or:
$sth = $dbh->prepare(qq{select * from `table`});
$sth->execute();
while(my $_somevar = $sth->fetchrow_hashref()) {
my $_someid = $_somvar->{primarykeyfield};
$sth2 = $dbh->prepare(qq{select * from `table1` where `primarykeyfield
+` = ?});
$sth2->execute($_someid);
$_thisvar = $sth2->fetchrow_hashref();
$sth2->finish();
# now I have data from table in $_somvar
# and data from table1 in $_thisvar
}
$sth->finish();
So, I call finish on them after I'm done reading from there, but not before. That way I don't leave any connections open, is that not correct?
Thanks,
Rich
