Question

The basic ideea is that when I call a procedure I want to get a set of data not just one value (by setting results to be INT and selection COUNT(id) for instance).
I would like to know how to change this procedure to get multiple values…

DELIMITER //
 CREATE PROCEDURE getnames(IN id_in INT,OUT results ???)
    BEGIN
        set results=(select name from people where id>id_in);
    END //
 DELIMITER ;

Answer 1

Unless I’ve misunderstood then you should simply be able to alter your procedure to the following

DELIMITER //
  CREATE PROCEDURE getnames(IN id_in INT)
    BEGIN
      select name from people where id>id_in;
    END //
DELIMITER ;

This will simply return the results of the select query, in this case the set of names.
