题目内容 (请给出正确答案)

You are the database administrator for a retail company. The company owns 270 stores. Every month, each store submits approximately 2,000 sales records, which are loaded into a SQL Server 2000 database at the corporate headquarters.

A Data Transformation Services (DTS) package transforms the sales records, as they are loaded. The package writes the transformed sales records to the Sales table, which has a column for integer primary key values. The IDENTITY property automatically assigns a key value to each transformed sales record.

After loading this month's sales data, you discover that a portion of the data contains errors. You stop loading data, identify the problem records, and delete those records from the database.

You want to reuse the key values that were assigned to the records that you deleted. You want to assign the deleted key values to the next sales records you load. You also want to disrupt users' work as little as possible.

What should you do?

A.Export all records from the Sales table to a temporary table. Truncate the Sales table, and then reload the records from the temporary table.

B.Export all records from the Sales table to a text file. Drop the Sales table, and then reload the records from the text file.

C.Use the DBCC CHECKIDENT statement to reseed the Sales table's IDENTITY property.

D.Set the Sales table's IDENTITY_INSERT property to ON. Add new sales records that have the desired key values.
