    In MySQL, SUM() function is used to return the total sum of a numeric column in a table.

    SUM() Syntax

    SELECT SUM(column_name) FROM table_name;
    

    We have a table "employee" as below:

        employee
        id  first_name            last_name       salary
        .......................................................
        1   John                     Simp         10000
        2   Chris                    Hely         25000
        3   Joy                      Roy          20000
        4   Jenny                    Mill         35000
    

    SUM() Example

    The below query gives the sum of all the "salary" column from the "employee" table:

    SELECT SUM(salary) AS total_salary FROM employee;
    

    Hope this will help you :)
