MindsDB supports standard SQL syntax, including the SQL aggregate functions. SQL aggregate functions perform calculations on a set of values and return a single result, making them useful for summarizing or analyzing data across multiple rows. Common aggregate functions include COUNT(), SUM(), AVG(), MIN(), and MAX(). These functions are used with GROUP BY to organize results by specific categories. 
SELECT
        year,
        SUM(salary) AS annual_salary
FROM salaries
GROUP BY year;
