QUESTION 84 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?

A. SELECT COUNT () FROM SaLeaOrders WHERE OrderTime = CONVERT(DATE, GETDATE ()) B. SELECT COUNT() FROM SalesOrders WHERE OrderTime - GETDATE() C. SELECT^ COUNT(-)^ FROM^ SaLesCrders WHERE CONCERT(VARCHAR, OrderTime, 112) = CONVERT (VARCHAR, GETDATE(I, 112) D. SELECT^ CCUNT(*)^ FROM^ SalesCrder WHERE CrderTime >= CONVERT(DATE, GETDATE()) AND CrderTime < DATEADD(DAY, CONVERT(DATS, 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

QUESTION 90 You have a database that contains the tables as shown below: You have a stored procedure named Procedure1. Procedure1 retrieves all order ids after a specific date.

70-461 Exam Dumps 70-461 Exam Questions 70-461 PDF Dumps 70-461 VCE Dumps

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 Parameter 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.

Answer: SELECT Orders.OrderID FROM Orders WHERE Orders.OrderDate>CONVERT(datetime,@Parameter1)
