Hello there,
I've SQL question, after I've created a table and insert its values
with the following statements
create table students (
id integer,
name varchar (20),
gender varchar (6),
college varchar (50),
grade int NOT NULL
phone_No number(10) NOT NULL ,
primary key (id),
UNIQUE (phone_No)
);
insert into students values
(1, 'Ahmed', 'male', 'Computer Science',10, 1234567890),
(2, 'Muhammad', 'male', 'Science',12, 2345678901),
(3,'Maha', 'female', 'Engineering', 10,3456789012),
(4, 'Reem', 'female', 'Nursing', 11, 4567890123),
(5, 'Khalid', 'male', 'Engineering', 12,5678901234),
(6, 'Badr', 'male', 'Science', 10,6789012345),
(7, 'Sarah', 'female', 'Nursing', 12, 7890123456);
and I were asked to run these:
c. SELECT DISTINCT gender FROM students
; // Now, it will return two rows
d. select grade from students. //it will sow only
the grades from the students table
e.
SELECT grade+ 3 AS FROM students;
// it will add 3 marks to all the students
f.
SELECT grade+ 3 AS updatedgrade FROM students
AS stu; // this will create a new table as name it as
updated_students_grade.
I've answerd all of them except Q.f ,I struggled with it.
