Question No : 19
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.)
070-461
You write the following Transact-SQL query:
070-461
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?
A. Use a FORCESCAN hint in the query.
B. Add a clustered index on SalesOrderId in SalesOrderHeader.
C. Use a FORCESEEK hint in the query.
D. Update statistics on SalesOrderId on both tables.
Answer: D
Explanation:

Question No : 20
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.
Which Transact-SQL query should you use?
A. SELECT COUNT(*)
FROM Purchases
WHERE PurchaseTime = CONVERT(DATE, GETDATE())
B. SELECT COUNT(*)
FROM Purchases
WHERE PurchaseTime = GETDATE()
C. SELECT COUNT(*) FROM Purchases
WHERE CONVERT(VARCHAR, PurchaseTime, 112) = CONVERT(VARCHAR,
GETDATE(), 112)
D. SELECT COUNT(*)
FROM Purchases
WHERE PurchaseTime >= CONVERT(DATE, GETDATE())
AND PurchaseTime < DATEADD(DAY, 1, CONVERT(DATE, GETDATE()))
Answer: D
Explanation:
Two answers will return the correct results (the “WHERE CONVERT…” and “WHERE …
AND … ” answers).
The correct answer for Microsoft would be the answer that is most “efficient”. Anybody
have a clue as to which is most efficient? In the execution plan, the one that I’ve selected
as the correct answer is the query with the shortest duration. Also, the query answer with
“WHERE CONVERT…” threw warnings in the execution plan…something about affecting
CardinalityEstimate and SeekPlan.
I also found this article, which leads me to believe that I have the correct answer:
