Microsoft Querying Microsoft SQL Server 2012/2014 Sample Questions:

Question 1

You have a database that contains the tables as shown in the exhibit. (Click the Exhibit button.)

You need to create a query that returns a list of products from Sales.ProductCatalog. The solution must meet the following requirements:
* UnitPrice must be returned in descending order.
* The query must use two-part names to reference the table.
* The query must use the RANK function to calculate the results.
* The query must return the ranking of rows in a column named PriceRank.
* The list must display the columns in the order that they are defined in the table.
* PriceRank must appear last.
Which code segment should you use?
To answer, type the correct code in the answer area.

A. SELECT ProductCatalog.CatID, ProductCatalog.CatName, ProductCatalog.ProductID, ProductCatalog.ProdName, ProductCatalog.UnitPrice, RANK() OVER (ORDER BY ProductCatalog.UnitPrice DESC) AS PriceRank ORDER BY ProductCatalog.UnitPrice DESC
B. SELECT ProductCatalog.CatID, ProductCatalog.CatName, ProductCatalog.ProductID, ProductCatalog.ProdName, ProductCatalog.UnitPrice, RANK() OVER (ORDER BY ProductCatalog.UnitPrice DESC) AS PriceRank FROM Sales.ProductCatalog ORDER BY ProductCatalog.UnitPrice DESC

Question 2

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.)


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 create a unique constraint?

A. MiddleName
B. JobTitle
C. DateHired
D. DepartmentID
E. ReportsToID
F. LastName
G. EmployeeNum
H. EmployeeID
I. FirstName

Question 3

You have a database application that uses Microsoft SQL Server 2012. You have a query named Query1 that returns four columns from a frequently updated table that has a clustered index. Three of the columns are referenced in the WHERE clause of the query. The three columns are part of a non-clustered index. The fourth column is not referenced in the WHERE clause.
Users report that the application begins to run slowly. You determine that the root cause for the performance issue is Query1.
You need to optimize the statement.
What should you do?

A. Include a SET FORCEPLAN ON statement before you run the query.
B. Include a SET TRANSACTION ISOLATION LEVEL SERIALIZABLE statement before you run the query.
C. Cover the unique clustered index with a columnstore index.
D. Add a FORCESEEK hint to the query.
E. Include a SET STATISTICS SHOWPLAN_XML ON statement before you run the query.
F. Add a columnstore index to cover the query.
G. Add a HASH hint to the query.
H. Add a LOOP hint to the query.
I. Enable the optimize for ad hoc workloads option.
J. Include a SET STATISTICS PROFILE ON statement before you run the query.
K. Add a FORCESCAN hint to the Attach query.
L. Include a SET TRANSACTION ISOLATION LEVEL REPEATABLE READ statement before you run the query.
M. Include a SET TRANSACTION ISOLATION LEVEL SNAPSHOT statement before you run the query.
N. Add an INCLUDE clause to the index.

Question 4

You create a table by using the following Transact-SQL Statement:

You need to return a result set that has a single column named DisplayInformation. The result set must contain the Name value if the Name value is NOT NULL, otherwise the result set must contain the SubName value.
Part of the correct Transact-SQL has been provided in the answer area below. Enter the code in the answer area that resolves the problem and meets the stated goals or requirements. You can add code within the code that has been provided as well as below it.


Use the Check Syntax button to verify your work. Any syntax or spelling errors will be reported by line and character position.

Question 5

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 create a Foreign Key constraint that references a different table in the database?

A. MiddleName
B. JobTitle
C. DateHired
D. DepartmentID
E. ReportsToID
F. LastName
G. EmployeeNum
H. EmployeeID
I. FirstName
