Which of the folowing is not a oracle function?
-
round
-
trunc
-
maximum
-
initcap
C
Correct answer
Explanation
Oracle SQL has ROUND, TRUNC, and INITCAP as built-in functions for numeric rounding, truncation, and string capitalization respectively. 'MAXIMUM' is NOT a valid Oracle function - the correct aggregate function is MAX (not MAXIMUM). This is a common trick question testing knowledge of exact function names.
