What I need is to join 2 tables
CREATE TABLE master( id INT4
);
CREATE TABLE slave ( master_id INT4, rank INT4, value TEXT);
What I need is to make the query:
SELECT m.id, array_agg(s.value) AS my_problematic_array
FROM master AS m LEFT JOIN slave AS s ON (m.id = s.master_id)
GROUP BY m.id;
return the 'my_problematic_array' in order specified by slave.rank
As you probably can guest I don't have any idea know how to do it :/
