The short answer is ... No.
The long answer is ...
How could the DBI (or the SQL and/or PL/SQL engine for that matter) know
in advance of getting the data, how much would be retrieved? According
to the concepts manual, part II, chapter 13 for 10gR2:
In a single-user database, the user can
I am using DBD::mysql and I can get the number of rows by assigning the
result of the execute to a scalar:
my $rows = $sth-execute or die "Couldn't execute statement: " .
DBI-errstr;
maybe this doesn't work with DBD::Oracle?
