[单选题]

You are the database administrator for a financial services company. Employees enter data 24 hours a day into a SQL Server 2000 database. These employees report slower response times when new account information is gathered from branch offices and added to the database. You currently use the following BULK INSERT statement to add the account information:

B.ULK INSERT finance.dbo.customers

F.ROM ‘di/bulk/accts143_10141000.txt’

WITH DATAFILETYPE = ‘char’,

F.IELD/TERMINATOR = ‘/t’,

ROWTERMINATOR = ‘/n,’

TABLOCK

You want to ensure that response times do not slow when new account information is added to the database. What should you do?

A.Drop the indexes for the customers table before the data load, and then re-create the indexes after the data load is complete.

B.Remove the TABLOCK option from the BULK INSERT statement.

C.Add the BATCHSIZE option to the BULK INSERT statement and then set the option equal to 10 percent of the number of rows to be loaded.

D.Add the ROWS_PER_BATCH option to the BULK INSERT statement and then set the option equal to 10 percent of the number of rows to be loaded.
