Explanation:
Since SQL Server 2008 you can also control how SQL Server performs the Lock Escalation - through the ALTER TABLE statement and the property LOCK_ESCALATION. There are 3 different options available:
TABLE
AUTO
DISABLE
Box 1: Table1, Auto
The default option is TABLE, means that SQL Server *always* performs the Lock Escalation to the table level -even when the table is partitioned. If you have your table partitioned, and you want to have a Partition Level Lock Escalation (because you have tested your data access pattern, and you don't cause deadlocks with it), then you can change the option to AUTO. AUTO means that the Lock Escalation is performed to the partition level, if the table is partitioned, and otherwise to the table level.
Box 2: Table 2, DISABLE
With the option DISABLE you can completely disable the Lock Escalation for that specific table.
For partitioned tables, use the LOCK_ESCALATION option of ALTER TABLE to escalate locks to the HoBT level instead of the table or to disable lock escalation.
