RETURN Example
The following database procedure example, emp_sales_rank, returns rows containing the employee ID, total sales, and rank of sales amongst current salesmen:
CREATE PROCEDURE emp_sales_rank
RESULT ROW (INT, INT, MONEY) AS
DECLARE
sales_tot MONEY;
empid INT;
sales_rank INT;
BEGIN
sales_rank = 0;
FOR SELECT e.empid, sum(s.sales) AS sales_sum INTO :empid, :sales_tot
FROM employee e, sales s
WHERE e.job = 'sales' AND e.empid = s.empid
GROUP BY e.empid ORDER BY sales_sum DO
sales_rank = sales_rank + 1;
RETURN ROW(:sales_rank, :empid, :tot_sales);
ENDFOR;
END
