Which operator returns true if the values on either side are equal to each other?

Explanation:
Equality checks in SQL rely on the equals operator. It evaluates to true only when the values on both sides match exactly. For example, 5 = 5 is true, while 5 = 7 is false. This is the operator you’d use in a WHERE clause to filter rows where two expressions are equal, or where a column equals a specific value. The other operators represent different comparisons: not equal (<>), greater-than (>), and less-than (<) do not indicate equality. Also, keep in mind that if NULL is involved, the equality comparison isn’t true in SQL’s three-valued logic; use IS NULL to check for missing values.
