Question

You need to find all students that are not on the Chemistry Cats team. Which query does NOT work for this task?

a) SELECT * FROM Students WHERE Team != 'Chemistry Cats';
b) SELECT * FROM Students WHERE NOT Team = 'Chemistry Cats';
c) SELECT * FROM Students WHERE Team <> 'Chemistry Cats';
d) SELECT * FROM Students WHERE Team NOT LIKE 'Chemistry Cats';

Answer 1

The correct query for finding all students that are not on the Chemistry Cats team is option c) SELECT * FROM Students WHERE Team <> 'Chemistry Cats';

Step-by-step explanation:

The correct query for finding all students that are not on the Chemistry Cats team is option c) SELECT * FROM Students WHERE Team <> 'Chemistry Cats';

Option a) SELECT * FROM Students WHERE Team != 'Chemistry Cats'; is incorrect because != is not the correct operator for inequality in SQL.

Option b) SELECT * FROM Students WHERE NOT Team = 'Chemistry Cats'; is also incorrect because NOT should be used with the NOT LIKE operator, not the equals operator.

Option d) SELECT * FROM Students WHERE Team NOT LIKE 'Chemistry Cats'; is incorrect because the NOT LIKE operator is used for pattern matching, but we need to check for exact inequality.
