You are developing a database that will contain price information.
You need to store the prices that include a fixed precision and a scale of six digits.
Which data type should you use?

You administer a Microsoft SQL Server 2012 database. The database contains a table
named Employee.
Part of the Employee table is shown in the exhibit. (Click the Exhibit button.)

Unless stated above, no columns in the Employee table reference other tables.
Confidential information about the employees is stored in a separate table named
EmployeeData. One record exists within EmployeeData for each record in the Employee table.
You need to assign the appropriate constraints and table properties to ensure data integrity
and visibility.
On which column in the Employee table should you a create a self-reference foreign key
constraint?

You use a Microsoft SQL Server 2012 database that contains a table named BlogEntry that
has the following columns:

Id is the Primary Key.
You need to append the “This is in a draft stage” string to the Summary column of the recent
10 entries based on the values in EntryDateTime.
Which Transact-SQL statement should you use?

You use Microsoft SQL Server 2012 to develop a database application.
You create a stored procedure named DeleteJobCandidate.
You need to ensure that if DeleteJobCandidate encounters an error, the execution of the
stored procedure reports the error number.
Which Transact-SQL statement 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?

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 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 runtime error, the entire transaction
is terminated and rolled back.
Which Transact-SQL statement should you include at the beginning of the stored
procedure?

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 administer a Microsoft SQL Server 2012 database named ContosoDb. Tables are
defined as shown in the exhibit. (Click the Exhibit button.)

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