Using NOLOCK politely asks SQL Server to ignore locks and
read directly from the tables. This means you completely
circumvent the lock system, which is a major performance
and scalability improvement. However, you also completely
circumvent the lock system, which means your code is living
dangerously. You might read the not-necessarily-valid
uncommitted modifications of a running transaction. This is
a calculated risk.
