Hi Audrius, How about this: > > q = db_session.query(func.regexp_split_to_array( > func.substring(Point.data, r'^POINT\((.*)\)$'), r'\s')) > for row in q: > print row > > q = db_session.query(cast(func.regexp_split_to_table( > func.substring(Point.data, r'^POINT\((.*)\)$'), r'\s'), Float)) > for row in q: > print row >
That works! Thank you very much! But somehow I am a little bit worried about the performance. Wouldn't trim() be much faster than regex?

Only the String-representation, which is of the format shown above (Yes, this is VERY annoying.)
