20. WITH (NOLOCK)
• TheWITH (NOLOCK) table hint is used to override the default
transaction isolation level of the table or the tables within the view
in a specific query.The query will consume less memory in holding
locks against that data and no deadlock will occur against the
queries that are requesting the same data from that table.
