You are a database developer. You develop a database by using SQL Server 2008 in an enterprise environment.
The database has a table named Sales.Inventory. The table is partitioned into four geographic regions. You update the Sales.Inventory table for each region by using the following stored procedure.
CREATE STORED PROCEDURE usp_Update
@RegionID tinyint
AS
UPDATE Sales.Inventory
SET Qty = T.CurrentQuantity
FROM Sales.Inventory I
JOIN Sales.TempData T ON I.ItemID = T.ItemID
AND I.RegionID = @RegionID;
The UPDATE statement locks the Sales.Inventory table when a single region is updated. You need to prevent the locking of the Sales.Inventory table when a single region is updated.
What should you do?
A. Modify the usp_Update stored procedure to use the NOLOCK table hint for the UPDATE statement.
B. Modify the usp_Update stored procedure to use the SERIALIZABLE table hint for the UPDATE statement.
C. Run the following Transact-SQL statement.
ALTER TABLE Sales.Inventory SET LOCK_ESCALATION = AUTO
D. Run the following Transact-SQL statement.
ALTER TABLE Sales.Inventory SET LOCK_ESCALATION = TABLE
