MIN()

MIN() is a SQL function in the Aggregate Functions category. Returns the minimum value from a group. The syntax is MIN(expression). It accepts expression — any comparable column. It returns minimum value. A typical example: SELECT MIN(salary) FROM employees; -- Lowest salary SELECT MIN(hire_date) FROM employees; -- Earliest hire date A close relative is COUNT(), which returns the number of rows (or non-NULL values) in a group. A close relative is SUM(), which returns the sum of all non-NULL values in a group. Works with numeric columns. A close relative is AVG(), which returns the average (mean) of all non-NULL values in a group. More about this category: Aggregation functions — COUNT, SUM, AVG, MIN, MAX, GROUP BY, HAVING.
