The Answer Is:
A, D
This question includes an explanation.
Explanation:
A. True. The DECODE function can evaluate conditions, but it is limited to equality checks. On the other hand, CASE can evaluate these and a broader range of conditions using different comparison operators.
D. True. DECODE is a function in Oracle SQL that allows for simple conditional query transformation. CASE is not a function but a statement that provides more flexibility and readability when handling conditional logic in SQL queries.
DECODE is more limited compared to CASE since it can't perform logical operations other than equality.
