The operator that does not perform relative-value comparisons is . . . . . . . .

Solution (By Examveda Team)

This question is about comparing values in MySQL. Let's break down the options:
Option A: = This operator checks if two values are equal. It's a relative comparison, meaning it compares one value to another.
Option B: == This operator also checks if two values are equal. It's like using '='.
Option C: <= This operator checks if the first value is less than or equal to the second value. It's also a relative comparison.
Option D: >= This operator checks if the first value is greater than or equal to the second value. Another relative comparison.

Since all the options involve comparing values in relation to each other, the answer is None of the above.
Think of it this way: All these operators ( =, ==, <=, >= ) are used to see how one value relates to another.
