Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 1 Sample Questions:

1. You use Microsoft SQL Server 2012 to write code for a transaction that contains several statements. There is high contention between readers and writers on several tables used by your transaction. You need to minimize the use of the tempdb space. You also need to prevent reading queries from blocking writing queries. Which isolation level should you use?

A) READ COMMITTED SNAPSHOT
B) SERIALIZABLE
C) REPEATABLE READ
D) SNAPSHOT

2. 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 (PARTITION BY ProductCatalog.UnitPrice ORDER BY ProductCatalog. UnitPrice DESC) AS PriceRank FROM Sales.ProductCatalog 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

3. 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?

A) Numeric
B) Float
C) Money
D) Smallmoney

4. You develop a Microsoft SQL Server 2012 database that contains tables named Employee and Person. The tables have the following definitions:

You create a view named VwEmployee as shown in the following Transact-SQL statement.

Users are able to use single INSERT statements or INSERT...SELECT statements into this view. You need to ensure that users are able to use a single statement to insert records into both Employee and Person tables by using the VwEmployee view. Which Transact-SQL statement should you use?

A) CREATE TRIGGER TrgVwEmployee ON VwEmployee INSTEAD OF INSERT AS BEGIN INSERT INTO Person(Id, FirstName, LastName) SELECT Id, FirstName, LastName, FROM inserted
INSERT INTO Employee(PersonId, EmployeeNumber)
SELECT Id, EmployeeNumber FROM inserted
END
B) CREATE TRIGGER TrgVwEmployee ON VwEmployee INSTEAD OF INSERT AS BEGIN
DECLARE @ID INT, @FirstName NVARCHAR(25), @LastName NVARCHAR(25), @PersonID INT, @EmployeeNumber NVARCHAR(15)
SELECT @ID = ID, @FirstName = FirstName, @LastName = LastName,
@EmployeeNumber = EmployeeNumber
FROM inserted
INSERT INTO Person(Id, FirstName, LastName)
VALUES(@ID, @FirstName, @LastName)
INSERT INTO Employee(PersonID, EmployeeNumber)
VALUES(@PersonID, @EmployeeNumber
End
C) CREATE TRIGGER TrgVwEmployee ON VwEmployee INSTEAD OF INSERT AS BEGIN INSERT INTO Person(Id, FirstName, LastName) SELECT Id, FirstName, LastName FROM VwEmployee
INSERT INTO Employee(PersonID, EmployeeNumber)
SELECT Id, EmployeeNumber FROM VwEmployee
End
D) CREATE TRIGGER TrgVwEmployee ON VwEmployee FOR INSERT AS BEGIN INSERT INTO Person(Id, FirstName, LastName) SELECT Id, FirstName, LastName, FROM inserted
INSERT INTO Employee(PersonId, EmployeeNumber)
SELECT Id, EmployeeNumber FROM inserted
END

5. You develop a database for a travel application. You need to design tables and other database objects. You create a stored procedure. You need to supply the stored procedure with multiple event names and their dates as parameters. What should you do?

A) Use the VARBINARY data type.
B) Use the FORMAT function.
C) Use the DATETIMEOFFSET data type.
D) Use the TODATETIMEOFFSET function.
E) Use the DATE data type.
F) Use the DATETIME2 data type.
G) Use an appropriate collation.
H) Use a user-defined table type.
I) Use the CAST function.
J) Use the DATETIME data type.
