To answer this question, we need to understand the syntax options for the CASE statement.
The CASE statement is used in SQL to perform conditional logic and return different values based on specified conditions.
There are two syntax options for the CASE statement:
- Simple CASE expression:
This syntax compares an expression to a set of values and returns a result based on the first matching value.
Example:
CASE expression
WHEN value1 THEN result1
WHEN value2 THEN result2
...
ELSE resultN
END
- Searched CASE expression:
This syntax evaluates multiple conditions and returns a result based on the first condition that evaluates to true.
Example:
CASE
WHEN condition1 THEN result1
WHEN condition2 THEN result2
...
ELSE resultN
END
Now, let's go through each option to understand why they are correct or incorrect:
Option A) True - This option is incorrect. Although both syntax options for the CASE statement provide the same functionality of conditional logic, they have different syntax structures.
Option B) False - This option is correct. The statement is false because the two syntax options for the CASE statement have different syntax structures.
The correct answer is B) False.
