You develop a Microsoft SQL Server 2012 database that contains a table named Customers. The
Customers table has the following definition. You need to create an audit record only when either
the MobileNumber or HomeNumber column is updated. Which Transact-SQL query should you
use?

You develop a Microsoft SQL Server 2012 server database that supports an application. The
application contains a table that has the following definition:
CREATE TABLE Inventory (
ItemID int NOT NULL PRIMARY KEY,
ItemsInStore int NOT NULL,
ItemsInWarehouse int NOT NULL)
You need to create a computed column that returns the sum total of the ItemsInStore and
ItemsInWarehouse values for each row. The new column is expected to be queried heavily, and
you need to be able to index the column. Which Transact-SQL statement should you use?

You administer a Microsoft SQL Server 2012 database named ContosoDb. Tables are defined as
shown in the exhibit.

You need to display rows from the Orders table for the Customers row having the CustomerId value
set to 1 in the following XML format.

Which Transact-SQL query should you use?

You administer a Microsoft SQL Server 2012 database named ContosoDb. Tables are defined as
shown in the exhibit. You need to display rows from the Orders table for the Customers row having
the CustomerId value set to 1 in the following XML format.
<CUSTOMERS Name=”Customer A” Country=”Australia”>
<ORDERS OrderID=”1″ OrderDate=”2001-01-01″ Amount=”3400.00″ />
<ORDERS OrderID=”2″ OrderDate=”2002-01-01″ Amount=”4300.00″ />
</CUSTOMERS>

Which Transact-SQL query 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 applications. What
should you create for each application?

You are writing a set of queries against a FILESTREAM-enabled database. You create a stored
procedure that will update multiple tables within a transaction. You need to ensure that if the stored
procedure raises a run-time error, the entire transaction is terminated and rolled back. Which
Transact-SQL statement should you include at the beginning of the stored procedure?

You use Microsoft SQL Server 2012 to develop a database application. Your application sends
data to an NVARCHAR(MAX) variable named @var. You need to write a Transact-SQL statement
that will find out the success of a cast to a decimal (36,9). Which code segment should you use?

You use Microsoft SQL Server 2012 to create a stored procedure as shown in the following code
segment. (Line numbers are included for reference only.) The procedure can be called within other
transactions. You need to ensure that when the DELETE statement from the
HumanResourcesJobCandidate table succeeds, the modification is retained even if the insert into
the Audit.Log table fails. Which code segment should you add to line 14?

A table named Profits stores the total profit made each year within a territory. The Profits table has
columns named Territory, Year, and Profit. You need to create a report that displays the profits
made by each territory for each year and its preceding year. Which Transact-SQL query should
you use?
