Use stored procedure in select

Question

Consider a stored procedure which returns a table:

DELIMITER //
CREATE PROCEDURE GetLegalAnimals (IN prop VARCHAR(128))
    BEGIN
        -- Lots of fiddling with temporary tables here
        SELECT
            animal, hit_points, terrain, weight, height, girth, attack, defence, quest
        FROM
            temp_animals;
    END //
DELIMITER ;

I would now like to filter the results of the returned table:

SELECT animal, terrain FROM GetLegalAnimals('rodent') WHERE hit_points<42;

The above query doesn't run as it is not valid MySQL syntax. Is there any way to perform such a query? I don't want to implement a separate GetLegalAnimals_* procedure for each of the (infinite) conditions, and I don't want to add additional parameters to the procedure as there are infinite SELECT and WHERE clause permutations.

Note that the stored procedure uses a parameter, so a view is not a suitable solution despite some creative solutions of the SO community.

Answer 1

If you want to use a whole table, you need a VIEW . First create the view

USE `yourdatabase`;
CREATE  OR REPLACE VIEW `GetLegalAnimals` AS
-- Lots of fiddling with temporary tables here
        SELECT
            animal, hit_points, terrain, weight, height, girth, attack, defence, quest
        FROM
            temp_animals;
;

Then you can query

SELECT animal, terrain FROM GetLegalAnimals WHERE hit_points < 42;

Answer 2

Use view instead of stored procedure

CREATE VIEW view_name AS
-- Lots of fiddling with temporary tables here
        SELECT
            animal, hit_points, terrain, weight, height, girth, attack, defence, quest
        FROM
            temp_animals;
