Question of the Day

Locking Hierarchies

You have a table [dbo].[orders] without a Clustered Index (Heap). The table does not have any other nonclustered indexes! You rund the following command in Read Committed Isolation Level: 

SELECTo_orderdate,
        o_orderkey,
        o_custkey,
        o_storekey
FROMdbo.orders
WHEREo_orderkey = 3877;

What locking hierarchy will Microsoft SQL Server use?
