> Getting value from result set using fully qualified name would throw exception. Only solution today is to use position of the column as opposed to column label.
> {code}
> String sql = "select r1.x, r2.x from r1 join r2 on r1.y=r2.y";
> ResultSet res = stmt.executeQuery(sql);
> res.getInt("r1.x");
> {code}
> res.getInt("r1.x"); would throw exception unknown column even though sql specifies it.
> Fix is to fix resultsetschema in semantic analyzer.
