CREATE TABLE employees
(
    `id` UInt32,
    `name` String,
    `salary` UInt32
)
ENGINE = Log

INSERT INTO employees VALUES
    (87432, 'John Smith', 45680),
    (59018, 'Jane Smith', 72350),
    (20376, 'Ivan Ivanovich', 58900),

We query for the total amount of the employee salaries using the sum function.
