> Given query cannot be executed as in a function body, but can be executed as
> a plain query. There is some issue with the variable counter in the language
> rewriting process which causes different variables has the same varId. This
> further causes mappings are overwritten in the variable substitution phase.

> fw.followers from Followers fw where fw.twitter_id= user_id ))
> where tw.user.id_str = user_id) t
> order by spatial_distance(sb.location,create_point(0,0)) limit 1
