Database code portability problem

Please correct me if I am misinterpreting this.

In the rdf.db.inc file, you have the following lines:

$result = db_query('SELECT DISTINCT g.uri g FROM {' . db_escape_table($table) . '} d INNER JOIN {rdf_resources} g ON d.gid = g.rid');

and

$sql = 'SELECT g.uri g, s.uri s, p.uri p, o.uri o, t.uri type, d.lang, d.data FROM {%s} d

For the first line, shouldn't g.uri g be g.uri AS g ??

and for the second line, shouldn't g.uri g, s.uri s, p.uri p, o.uri o, t.uri type be g.uri AS g, s.uri AS s, p.uri AS p, o.uri AS o, t.uri AS type

I believe not all sql languages assume the AS keyword.
