Many database records are linked in a many to many relationship with other tables or records. Consider the following query:
(query "select countries.id, countries.name, events.name as event from countries,events,countries_events where country_id=countries.id and events.id=event_id and events.id=$1" 29)This can be rephrased in s-sql as:
(query (:select 'countries.id 'countries.name (:as 'events.name 'event) :from 'countries 'events 'countries_events :where (:and (:= 'country_id 'countries.id) (:= 'events.id 'event_id) (:= 'events.id '$1))) 29)
