考题
Your company uses SQL Server 2005. You are implementing a series of views that are used in ad hoc queries. The views are used to enforce your companys security policy of abstracting data. Some of these views perform slowly. You create indexes on those views to increase performance, while still maintaining the companys security policy. One of the views returns the current date as one of the columns. The view returns the current date by using the GETDATE（ ） function. This view does not allow you to create an index. You need to create an index on the view. Which two actions should you perform?（）A、 Remove all deterministic function calls from within the view. B、 Remove all nondeterministic function calls from within the view. C、 Schema-bind all functions that are called from within the view. D、 Create the view and specify the WITH CHECK OPTION clause.

单选题You design a Business Intelligence （BI） solution by using SQL Server 2008. You plan to create a SQL Server 2008 Reporting Services （SSRS） solution. Developers generate random reports against a data source that contains 200 tables. Power users generate random reports against four of the 200 tables. You need to design a strategy for the SSRS solution to meet the following requirements： ·Uses minimum amount of development effort. ·Provides two sets of tables in SSRS to the developers group and the power users group. Which strategy should you use？（）A
Create two Report Builder models.Include the four frequently used tables in the first model and all the tables in the second model.B
Create a Report Builder model by using all the tables.Create a perspective within the model to use only the four frequently used tables.C
Create a Report Builder model by using all the tables. Create two folders.Place the four frequently used tables in the first folder and the remaining tables in the second folder.D
Create two Data Source Views.Include all the tables in one Data Source View and the four frequently used tables in the other Data Source View.Create two Report Builder models so that each model uses one of the Data Source Views.
