You are the administrator of a SQL Server 2000 computer. The server contains a database that stores financial data. You want to use Data Transformation Services packages to import numeric data from other SQL server computers. The precision and scale values of this data are not defined consistently on the other servers.
You want to prevent any loss of data during the import operations. What should you do?
A．Use the ALTER COLUMN clause of the ALTER TABLE statement to change data types in the source tables. Change the data types so that they will use the lowest precision and scale values of the data that will be transferred.
B．Use the ALTER COLUMN clause of the ALTER TABLE statement to change data types in the destination tables. Change the data types to reflect the highest precision and scale values involved in data transfer.
C．Set a flag on each DTS transformation to require an exact match between source and destination columns.
D．Set the maximum error count for each DTS transformation task equal to the number of rows of data you are importing. Use an exception file to store any rows of data that generate errors.
E．Write Microsoft ActiveX script. for each DTS transformation. Use the script. to recast data types to the destinations precision and scale values.

第3题：
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.

While investigating the reason， you find that the mapping table segment is fragmented， leading to poor performance. Which option would you use to defragment the mapping table without affecting the original table data？（）
