Return multiple fields as a record in PostgreSQL with PL/pgSQL

Question

I am writing a SP, using PL/pgSQL.
I want to return a record, comprised of fields from several different tables. Could look something like this:

CREATE O         


        

Answer 1

You can achieve this by using simply as a returns set of records using return query.

CREATE OR REPLACE FUNCTION schemaName.get_two_users_from_school(schoolid bigint)
 RETURNS SETOF record
 LANGUAGE plpgsql
AS $function$
begin

 return query
  SELECT id, name FROM schemaName.user where school_id = schoolid;

end;
$function$

And call this function as : select * from schemaName.get_two_users_from_school(schoolid) as x(a bigint, b varchar);
