  4. max( )

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Group functions (aggregate functions) like MIN(), MAX(), and SUM() operate on multiple rows and return a single result. SQRT() is a scalar function that operates on individual values, returning the square root of a single number, making it the correct answer as 'not a group function'.

C Correct answer
Explanation

In IBM COBOL with ARITH(COMPAT) compiler option, the FACTORIAL function accepts integer arguments from 0 to 28 maximum. This is due to the storage size limitations for the result - values beyond 28! exceed standard numeric representation capacity.

B,D Correct answer
Explanation

Scalar functions operate on single values and return single values. MID() extracts a substring from a text value, and NOW() returns the current timestamp - both are scalar. MAX() and SUM() are aggregate functions that operate on multiple rows and return summary values.

A Correct answer
Explanation

The system limits keyword functions to a maximum of 63 characters. This is a common technical constraint in many systems that ensures manageable function names and prevents excessively long identifiers.
