DROP TABLE programmer CASCADE CONSTRAINTS;
CREATE TABLE Programmer
{
EmpNo            Varchar2(3)        PRIMARY KEY,
Last_Name         Varchar2(25)    NOT NULL,
First_Name        Varchar2(25),
Hire_Date        Date,
Project            Varchar2(3),
Language        Varchar2(15),
TaskNo            Number(2),
Clearance        Varchar2(25)
);
