考题 You are the administrator of a SQL Server 2000 computer. You are creating a data transformation services package. As the first step in this process, you need to load data from text files into a database table. These text files contain data on new stores that join your franchise. The text files list the data columns in the following format StoreID, StoreName, Address, City, State, PostalCode, ManagerID, StoreTypeID, FacilityID.The destination table is configured as shown in the exhibit.You want to load the data into the table as quickly as possible. What should you do?A.Use a Bulk Insert Task to read the data into a temporary table. Use an Execute SQL task to import the appropriate data into the destination table.B.Create and edit a format file to select the columns you want to import. Use a Bulk Insert Task, and then specify the format file to import the appropriate data into the destination table.C.Use a transform. data task to import the data. Use Microsoft ActiveX transformation scripts to write the appropriate data to the appropriate columns in the destination table.D.Create and edit a format file to select the columns you want to import. Use a transform. data task, and then specify the format file to import the appropriate data into the destination table.
