a$.$ Assuming the course table has been deleted from a university database, the task is to recreate this table with the same structure previously used. In addition to the original structure, a new constraint needs to be added to ensure the credits column has values greater than one. This constraint should be named credit$\_$check. Write an SQL statement to create the course table and include the credit$\_$check constraint.

b$.$ After evaluating the requirements for the course table in a university database again, it has been decided that the constraint on the credits column, which ensures credits are greater than one, is no longer necessary. Write an SQL statement to remove the credit$\_$check constraint from the course table.LAM.pdf
