Solution 1

Your datediff function requires three arguments in the format:

DATEDIFF(interval, date1, date2)

and you've only supplied two.
Take a look here at some examples. SQL Server DATEDIFF() Function[^]

Exactly what it says. Go to the documentation for DATEDIFF to see what parameters are required: DATEDIFF (Transact-SQL) - SQL Server | Microsoft Docs[^]

The error is in your actual SQL statement. The DateDiff function requires 3 parameters; and is in the format DATEDIFF(datepart, startdate, enddate )

Based on the alias you have assigned to the function (Days_Elapse), I am guessing you would want to be using something like this:

SQL

SELECT Car_ID
,      Cust_ID
,      Rental_Due
,      DATEDIFF(DD, GETDATE(),Rental_Due) as Days_Elapse -- DD: Days
FROM   CarRental
WHERE Car_ID =?

Exactly what the message said: the datediff function requires 3 argument(s).
and your code only provide 2 arguments.
You need to read documentation to see how datediff works.
