UpdateQuery_oracle

Hi,

I'm not sure if it's a bug, but when I'm using update query, UpdateQuery_oracle's execute procedure calls :

// Fetch the list of blobs and sequences used on that table.
$info= $this->connection->schema()->getTableInfo($this->table);

And then the $info variable isn't used anymore. As I didn't used the driver to install Drupal, the query fails.
select identifier.sequence_for_table(?,?) sequence_name from dual

Removing this variable is safe, isn't it ?

Cheers.
