Please Check My Simple DDL Script - Fix Mistakes If Any

Asked by: F-J-K

Is it ok to do CHECK (leavingdate >= hiredate)?

I don't have the tools yet to check my script.

CREATE TABLE EmployeeHistory
(
	employeehistoryid number(10) CONSTRAINT employeehistoryid_pk PRIMARY KEY,
	salary number(9,2) NOT NULL,
	motelname varchar2(50) NOT NULL,
	jobtype varchar2(50) NOT NULL,
	hiredate date NOT NULL,
	leavingdate date NOT NULL CHECK (leavingdate >= hiredate)
);
