The following MySQL statement belongs to which condition types?

FROM person
WHERE fed_id=’111-11-111’;
SELECT fname
FROM person
WHERE fed_id=’111-11-111’;
A. Equality condition
B. Inequality condition
C. Range condition
D. All of the mentioned
Answer: Option A
Solution (By Examveda Team)
This MySQL statement uses an equality condition.Let's break it down:
* SELECT fname FROM person : This part tells MySQL to retrieve the "fname" (first name) column from the "person" table.
* WHERE fed_id='111-11-111'; : This is the important part! The WHERE clause filters the data. We're looking for rows where the "fed_id" column is equal to '111-11-111'. That's an equality comparison.
Here's why the other options are incorrect:
* Inequality condition: An inequality condition would use operators like != (not equal), < (less than), > (greater than), etc.
* Range condition: A range condition would use operators like BETWEEN to specify a range of values.
Therefore, the correct answer is Option A: Equality condition.
