Issue/Introduction
This document provides an example of how to use a PROCEDURE to place an exclusive lock on a record occurrence.
There is no way to place the equivalent of an EXCLUSIVE LOCK on a record occurrence using SQL syntax. There is a FOR UPDATE clause but it is designed to impact the optimization of the query and doesn't place any additional locks.
