title: Concurrent access to MySQL Stored Procedure
body: <p>I am using a stored procedure to update a table with doing some calculations. What I am worrying about is if multiple users access this stored procedure concurrently, my calculations will be wrong. I don't know this is possible as I don't have much knowledge about MySQL. What I want to achieve is allow access to stored procedure only one user at a time. Is this situation handled by default or do I have to do some extra works.</p>
