MySQL Arithmetic Functions

 How to work Arithmetic Functions:

Code:

CREATE TABLE personal(

id INT NOT NULL,

name VARCHAR(50) NOT NULL,

    percentage INT NOT NULL,

age INT NOT NULL,

gender VARCHAR(1) NOT NULL,

city INT NOT NULL,

    courses INT NOT NULL,

    PRIMARY KEY (id),

FOREIGN KEY (city) REFERENCES City (cid),

    FOREIGN KEY (courses) REFERENCES Courses (course_id)  

);

INSERT INTO personal(id,name,percentage,age,gender,city,courses)

VALUES

(1,"Aqib","45","13","M",1,1),

(2,"Khadija","56","21","F",2,2),

(3,"Salman Khan","62","20","M",1,1),

(4,"Aqeela","47","18","F",3,1),

(5,"Saqib","74","22","M",1,3),

(6,"Abraham","64","21","M",2,2),

(7,"Shahid","52","20","M",1,3);
