NOT can negate IN, Between, LIKE or conditional statement

NOT can negate IN, Between, LIKE or conditional statement

• A. NOT
• B. Between
• C. COALESCE
• D. CAST

Answer: (A)

The main concept here is using the negation operator to flip the truth of a predicate in SQL. NOT acts as a universal negator for conditions, so it can be applied to IN, BETWEEN, LIKE, or any boolean expression. NOT IN turns a membership test into the opposite: it selects rows where the value is not in the given set or subquery. NOT BETWEEN excludes values inside the specified inclusive range, yielding rows outside that range. NOT LIKE inverts a pattern match, returning rows whose strings do not match the pattern. And NOT can negate any conditional statement, such as NOT (age > 18 AND status = 'active'), or NOT EXISTS, by flipping that boolean result. The other options don’t serve all these negation roles: BETWEEN by itself checks for inclusion in a range, not its negation; COALESCE returns the first non-null value, not a negation; CAST changes data types, also not a negation.
