Your database contains a table named SalesOrders. The table includes a DATETIME column named
OrderTime that stores the date and time each order is placed. There is a non-clustered index on the
OrderTime column. The business team wants a report that displays the total number of orders
placed on the current day.
You need to write a query that will return the correct results in the most efficient manner.
Which Transact-SQL query should you use?

You are developing a database application by using Microsoft SQL Server 2012. You have a query
that runs slower than expected.
You need to capture execution plans that will include detailed information on missing indexes
recommended by the query optimizer.
What should you do?

You use Microsoft SQL Server 2012 to develop a database application. You create a stored procedure
named dbo.ModifyData that can modify rows.
You need to ensure that when the transaction fails, dbo.ModifyData meets the following
requirements:
Does not return an error
Closes all opened transactions
Which Transact-SQL statement should you use?

You are developing a database application by using Microsoft SQL Server 2012. An application that
uses a database begins to run slowly.
You discover that a large amount of memory is consumed by single-use dynamic queries.
You need to reduce procedure cache usage from these statements without creating any additional
indexes.
What should you do?

You create a table that has the StudentCode, SubjectCode, and Marks columns to record mid-year
marks for students. The table has marks obtained by 50 students for various subjects.
You need to ensure that the top half of the students arranged by their average marks must be given
a rank of 1 and the remaining students must be given a rank of 2.
Which Transact-SQL query should you use?

You develop a database for a travel application.
You need to design tables and other database objects.
You create the Airline_Schedules table.
You need to store the departure and arrival dates and times of flights along with time zone
information.
What should you do?

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?

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?

DRAG DROP
You want to add a new GUID column named BookGUID to a table named dbo.Book that already
contains data.
BookGUID will have a constraint to ensure that it always has a value when new rows are inserted
into dbo.Book. You need to ensure that the new column is assigned a GUID for existing rows. Which
four Transact-SQL statements should you use? (To answer, move the appropriate SQL statements
from the list of statements to the answer area and arrange them in the correct order.)

DRAG DROP
You create a view based on the following statement:

You grant the Select permission to User1 for this view. You need to change the view so that it
displays only the records that were processed in the month prior to the current month. You need to
ensure that after the changes, the view functions correctly for User1. Which four Transact-SQL
statements should you use? (To answer, move the appropriate SQL statements from the list of
statements to the answer area and arrange them in the correct order.)
