3. What is the difference between Column Level and Table Level Constraints?

1. Constraints are applied to a single row using Column Level Constraints whereas Multiple rows can be constrained using a Table Level Constraint.
2. Constraints are applied to multiple rows using Column Level Constraints whereas a single row can be constrained using a Table Level Constraint.
3. Constraints are applied to a single column using Column Level Constraints whereas Multiple columns can be constrained using a Table Level Constraint.
4. Constraints are applied to multiple columns using Column Level Constraints whereas only a single column can be constrained using a Table Level Constraint.

Answer: C) Constraints are applied to a single column using Column Level Constraints whereas Multiple columns can be constrained using a Table Level Constraint

Explanation:

Constraints are applied to a single column using Column Level Constraints whereas Multiple columns can be constrained using a Table Level Constraint.
