第1题:

You are the administrator of a SQL Server 2000 computer in your company's personnel department. Employee data is stored in a SQL Server 2000 database. A portion of the database schema is shown in the exhibit.

You want to create a text file that lists these data columns in the following format title, FirstName, LastName, WorkPhone, PositionName, DepartmentName.

You want to create the text file as quickly as possible. You do not expect to re-create this file, and you want to avoid creating new database objects if possible.

What should you do?

A.Use the bcp utility to export data from each table to a separate text file. Use format files to select the appropriate columns. Merge the data from each text file into a single text file.

B.Create a view that joins data from all three tables include only the columns you want to appear in the text file. Use the bcp utility to export data from the view.

C.Create a SELECT query that joins the data from the appropriate columns in the three tables. Add an INTO clause to the query to create a local temporary table. Use the bcp utility to export data from the local temporary table to a text file.

D.Create a SELECT query that joins the data from the appropriate columns in the three tables. Add an INTO clause to the query to create a global temporary table. Use the bcp utility to export data from the global temporary table to a text file.

第6题:

You are the administrator of a SQL Server 2000 computer. Your company uses the server to store service contract information for its customers.

You are also the administrator of Oracle relational database management system (RDBMS) server.

This server is used to store your company’s financial information. The financial information is updated frequently throughout the day.

You need to create a series of reports that combine the service contract information and the financial information. These reports will be updated several times a day.

You want to create reports on the SQL Server computer by using the minimum amount of disk space.

What should you do?

A.Set up SQL server replication to replicate the data from the oracle server to the SQL server computer.

B.Set up the oracle server as a linked server. Create a view that joins the service contract information and the financial information.

C.Set up data transformation services (DTS) package that imports and transforms the database from the oracle server to the SQL server computer. Use SQL server agent to execute the DTS package throughout the day as needed.

D.Set up Microsoft ActiveX script. that connects to the oracle server and imports the financial information into SQL server temporary table. Create a view that joins the service contract information and the temporary table.


正确答案:B
解析:Explanation: SQL Server 2000 permits the creation of links to OLE DB data sources called linked servers. After linking to an OLE DB data source, it is possible to reference rowsets from the OLE DB data sources as tables in Transact-SQL statements and to pass commands to the OLE DB data sources and include the resulting rowsets as tables in Transact-SQL statements.

Each distributed query can reference multiple linked servers and can perform. either update or read operations against each individual linked server. A single distributed query can perform. read operations against some linked servers and update operations against other linked servers. The Microsoft OLE DB Provider for Oracle allows distributed queries to query data in Oracle databases.

Incorrect Answers:
A: Replication allows for the coping, distribution, and modification of data across an enterprise. This involves the copying of database data from one server to another. This is not the best solution in this scenario as this will require frequent replication because the reports must be updated several times a day.

C: Data Transformation Services is a set of graphical tools and programmable objects that allows for the extraction, transformation, and consolidation of data from disparate sources into single or multiple destinations. In this scenario, however, the Oracle database needs to be included in a query. Hence, Data Transformation Services are inappropriate.

D: Microsoft ActiveX scripts can be used to add functionality to Data Transformation Services packages, which is a set of graphical tools and programmable objects that allows for the extraction, transformation, and consolidation of data from disparate sources into single or multiple destinations. In this scenario, however, the Oracle database needs to be included in a query. Hence, Data Transformation Services are inappropriate.

第8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.
