Case Study
BackgroundYou have a database named HR1 that includes a table named Employee.
You have several read-only, historical reports that contain regularly changing totals. The reports use multiple
queries to estimate payroll expenses. The queries run concurrently. Users report that the payroll estimate
reports do not always run. You must monitor the database to identify issues that prevent the reports from
running.
You plan to deploy the application to a database server that supports other applications. You must minimize the
amount of storage that the database requires.
Employee Table
You use the following Transact-SQL statements to create, configure, and populate the Employee table:

Application
You have an application that updates the Employees table. The application calls the following stored
procedures simultaneously and asynchronously:
UspA: This stored procedure updates only the EmployeeStatus column.
UspB: This stored procedure updates only the EmployeePayRate column.
The application uses views to control access to data. Views must meet the following requirements:
Allow user access to all columns in the tables that the view accesses.
Restrict updates to only the rows that the view returns.
Exhibit

Both of the stored procedures experience blocking issues. UspB must not abort if UspA commits changes to a
row before UspB commits changes to the same row. UspA must not abort if UspB commits changes to a row
before UspA commits changes to the same row.
You need to specify the transaction isolation levels to enable row versioning.
How should you complete the Transact-SQL statements? To answer, drag the Transact-SQL segments to the
correct locations. Each Transact-SQL segment may be used once, more than once, or not at all. You may need
to drag the split bar between panes or scroll to view content.

Exhibit

Users must only be able to modify data in the Employee table by using the vwEmployee view. You must prevent
users from viewing the view definition in catalog views.
You need to identify the view attribute to use when creating vwEmployee.
In the table below, identify the attributes that you must use.
NOTE: Make only one selection in each column.

You are analyzing the performance of the database environment. You discover that locks that are held for a
long period of time as the reports are generated.
You need to generate the reports more quickly. The database must not use additional resources.
