Which query should you use?
Your database contains two tables named DomesticSalesOrders and InternationalSalesOrders. Both
tables contain more than 100 million rows. Each table has a Primary Key column named
SalesOrderId. The data in the two tables is distinct from one another.
Business users want a report that includes aggregate information about the total number of global
sales and total sales amounts.
You need to ensure that your query executes in the minimum possible time.
Which query should you use?
Which stored procedure option should you use?
You are a database developer at an independent software vendor. You create stored procedures
that contain proprietary code.
You need to protect the code from being viewed by your customers.
Which stored procedure option should you use?
Which Transact-SQL statement should you use?
You use a Microsoft SQL Server 2012 database.
You want to create a table to store Microsoft Word documents.
You need to ensure that the documents must only be accessible via Transact-SQL queries.
Which Transact-SQL statement should you use?
Which Transact-SQL batch should you use?
You administer a Microsoft SQL Server 2012 database that contains a table named OrderDetail. You
discover that the NCI_OrderDetail_CustomerID non-clustered index is fragmented. You need to
reduce fragmentation.
You need to achieve this goal without taking the index offline. Which Transact-SQL batch should you
use?
What should you create for each application?
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 existing applications.
What should you create for each application?
Which object should you use?
You develop a Microsoft SQL Server 2012 database.
You need to create a batch process that meets the following requirements:
Returns a result set based on supplied parameters.
Enables the returned result set to perform a join with a table.
Which object should you use?
Which Transact-SQL statement or statements should you use?
You develop a Microsoft SQL Server 2012 database.
You need to create and call a stored procedure that meets the following requirements:
Accepts a single input parameter for CustomerID.
Returns a single integer to the calling application.
Which Transact-SQL statement or statements should you use? (Each correct answer presents part of
the solution. Choose all that apply.)
Which table hint should you use?
You develop a Microsoft SQL Server 2012 database that contains a heap named OrdersHistoncal.
You write the following Transact-SQL query:
INSERT INTO OrdersHistorical
SELECT * FROM CompletedOrders
You need to optimize transaction logging and locking for the statement. Which table hint should you
use?
You need to improve the performance of the query
You use a Microsoft SQL Server 2012 database that contains two tables named SalesOrderHeader
and SalesOrderDetail. The indexes on the tables are as shown in the exhibit. (Click the Exhibit
button.)
You write the following Transact-SQL query:
You discover that the performance of the query is slow. Analysis of the query plan shows table scans
where the estimated rows do not match the actual rows for SalesOrderHeader by using an
unexpected index on SalesOrderDetail.
You need to improve the performance of the query.
What should you do?
Which Transact-SQL query should you use?
Your database contains a table named Purchases. The table includes a DATETIME column named
PurchaseTime that stores the date and time each purchase is made. There is a non-clustered index
on the PurchaseTime column.
The business team wants a report that displays the total number of purchases made on the current
day.
You need to write a query that will return the correct results in the most efficient manner.
