$(1)$ MySQL allows for specification of domain constraints as so called CHECK constraint in CREATE TABLE

statement of SQL$.$ However, at the moment, the latest version of MySQL does not automatically enforce

such constraints in a database.

It is possible to enforce a domain constraint in a different way than directly through CREATE TABLE

statement.

Implement SQL script that enforces a constraint listed below in the sample database.

The total hours for each employee works on the projects must be less than or equals to $40$ hours.

List the employee number, name and the message $$works on the projects more than $40$ hours$$ for the

employees who violate the above constraint.
