# Demonstrate how to perform a simple query limiting the rows retrieved using
# a bind variable. Since the query that is executed is identical, no additional
# parsing is required, thereby reducing overhead and increasing performance. It
# also permits data to be bound without having to be concerned about escaping
# special characters or SQL injection attacks.
