You have a database that contains the tables shown in the exhibit. (Click the Exhibit button.)
You have a stored procedure named Procedure1. Procedure1 retrieves all order ids after a specific date.
The rows for Procedure1 are not sorted.
Procedure1 has a single parameter named Parameter1. Parameter1 uses the varchar type and is
configured to pass the specific date to Procedure1.
A database administrator discovers that OrderDate is not being compared correctly to Parameter1 after the
data type of the column is changed to datetime.
You need to update the SELECT statement to meet the following requirements:
*The code must NOT use aliases.
*The code must NOT use object delimiters.
*The objects called in Procedure1 must be able to be resolved by all users. *OrderDate must be compared
to Parameter1 after the data type of Parameter1 is changed to datetime.
Which SELECT statement should you use?
To answer, type the correct code in the answer area.
A. SELECT OrderID FROM Orders
WHERE OrderDate>CONVERT(datetime,@Parameter1)
B. SELECT Orders.OrderID FROM Orders WHERE Orders.OrderDate>CONVERT(datetime,@Parameter1)

Correct Answer: D Explanation
Explanation/Reference:
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.
