Q1. 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 SalesOrders 

WHERE OrderTime = CONVERT(DATE, GETDATE()) 

B. SELECT COUNT(*) FROM SalesOrders 

WHERE OrderTime = GETDATE() 

C. SELECT COUNT(*) FROM SalesOrders 

WHERE CONVERT(VARCHAR, OrderTime, 112) = CONVERT(VARCHAR, GETDATE(I, 

112)) 

D. SELECT COUNT(*) FROM SalesOrders 

WHERE OrderTime >= CONVERT(DATE, GETDATE()) 

AND OrderTime < DATEADD(DAY, 1, CONVERT(DATE, GETDATE()))
