You can't join with a procedure, but you can do it with a view, which can be treated like a table (although there are some restrictions).
CREATE VIEW sales_view AS
SELECT * FROM sales;
SELECT *
FROM sales AS s
JOIN sales_view AS sv ON s.rep_id = sv.rep_id
You can't pass parameters to a view, but you can access columns in the WHERE clause.
SELECT *
FROM sales AS s
JOIN sales_view AS sv ON s.rep_id = sv.rep_id
WHERE sv.quantity > 10;
