If i use a parameterised query such as the one shown below, how do i get the actual sql that the db engine failed to execute? 

my $update_meta_sql = "update runmeta set known_snps=? where run_id=?"
+;
unless ($db->do($update_meta_sql, undef, $updates, $run_id)) {
    
    $status = "failed at  update runmeta";

        }
