You have three tables that contain data for vendors, customers, and agents. You create a view that is used to look up telephone numbers for these companies.
The view has the following definition:

You need to ensure that users can update only the phone numbers by using this view.
What should you do?

You are a database developer of a Microsoft SQL Server 2012 database.
You are designing a table that will store Customer data from different sources. The table will include a column that contains the CustomerID from the source system
and a column that contains the SourceID.
A sample of this data is as shown in the following table.

You need to ensure that the table has no duplicate CustomerID within a SourceID. You also need to ensure that the data in the table is in the order of SourceID and
then CustomerID.
Which Transact- SQL statement should you use?

You develop a database for a travel application. You need to design tables and other database objects.
You create a view that displays the dates and times of the airline schedules on a report.
You need to display dates and times in several international formats.
What should you do?

You develop a database for a travel application. You need to design tables and other database objects.
You need to store media files in several tables.
Each media file is less than 1 MB in size. The media files will require fast access and will be retrieved frequently.
What should you do?

Your database contains a table named Purchases. The table includes a DATETIME column named PurchaseTime that stores the date and time each purchase is
made. There is a non- clustered index on the PurchaseTime column.
The business team wants a report that displays the total number of purchases made on the current day.
You need to write a query that will return the correct results in the most efficient manner.
Which Transact-SQL query should you use?

You use a Microsoft SQL Server 2012 database that contains two tables named SalesOrderHeader and SalesOrderDetail. The indexes on the tables are as shown
in the exhibit.
(Click the Exhibit button.)

You write the following Transact-SQL query:

You discover that the performance of the query is slow. Analysis of the query plan shows table scans where the estimated rows do not match the actual rows for
SalesOrderHeader by using an unexpected index on SalesOrderDetail.

You need to improve the performance of the query.
What should you do?

You develop a Microsoft SQL Server 2012 database that contains a heap named OrdersHistoncal.
You write the following Transact-SQL query:
INSERT INTO OrdersHistorical
SELECT * FROM CompletedOrders

You need to optimize transaction logging and locking for the statement. Which table hint should you use?

You develop a Microsoft SQL Server 2012 database.
You need to create and call a stored procedure that meets the following requirements:
Accepts a single input parameter for CustomerID.
Returns a single integer to the calling application.
Which Transact-SQL statement or statements should you use? (Each correct answer presents part of the solution. Choose all that apply.)

You develop a Microsoft SQL Server 2012 database.
You need to create a batch process that meets the following requirements:
Returns a result set based on supplied parameters.
Enables the returned result set to perform a join with a table.
Which object should you use?

You develop a Microsoft SQL Server 2012 database. The database is used by two web applications that access a table named Products.
You want to create an object that will prevent the applications from accessing the table directly while still providing access to the required data.
You need to ensure that the following requirements are met:
Future modifications to the table definition will not affect the applications’ ability to access data.
The new object can accommodate data retrieval and data modification. You need to achieve this goal by using the minimum amount of changes to the existing
applications.
What should you create for each application?
