如何在mySql中多次执行select语句？

Question

Hi i am trying to benchmark the select performance of mySql database. I am wondering how I can execute the select statement multiple times. At the moment I have the following loop :

BEGIN
label1: LOOP
SET p1 = p1 - 1;
IF p1 > 0 THEN
SELECT * FROM FOOD WHERE ID = p1;
ITERATE label1;
END IF;
LEAVE label1;
END LOOP label1;
END

However when running this stored procedure in phpMyAdmin it returns no results.

Update

Stored procedure code

CREATE DEFINER=`root`@`localhost` PROCEDURE `mySelect`(IN `p1` INT)
    DETERMINISTIC
BEGIN
label1: LOOP
SET p1 = p1 - 1;
IF p1 > 0 THEN
SELECT * FROM FOOD where id = p1;
ITERATE label1;
END IF;
LEAVE label1;
END LOOP label1;
END 

How can I execute a select statement like this multiple times eg 1000 to see how long (ms) it takes to run?

I agree with strawberry... I used mysqlslap

>mysqlslap --concurrency=50 --iterations=5 --query=test1.sql --create-schema=test -uroot -p
Benchmark
        Average number of seconds to run all queries: 0.031 seconds
        Minimum number of seconds to run all queries: 0.031 seconds
        Maximum number of seconds to run all queries: 0.031 seconds
        Number of clients running queries: 50
        Average number of queries per client: 1

Inside test1.sql I wrote:

SELECT * FROM food WHERE id=(1+ FLOOR(RAND() * 10))
