CREATE TABLE STUDENT (NAME CHARACTER(25), ROLLNO int PRIMARY KEY, AREACODE int, REGD_YEAR date)  

2.Insert some data for checking the query

 insert into student values(101,'Mark',203,'03-12-1997')  

            insert into student values(106,'Zack',204,'06-18-1992')

 insert into student values(104,'Jess',203,'01-11-1995')

3.Select query for creating a list of student names from area code 203

SELECT NAME AS "Student Name", AREACODE, REGD_YEAR

FROM STUDENT

ORDER BY “REGD_YEAR“,”Student Name”;
