MAX

Calculates the maximum value of an expression across all input values.

Syntax

MAX(<expr>)
Parameter Description
<expr> The expression used to calculate the maximum values. Valid values for the expression include a column name or functions that return a column name.

Example

For this example, we’ll create a new table prices as shown below.

CREATE DIMENSION TABLE IF NOT EXISTS prices
    (
        item TEXT,
        price INT
    );

INSERT INTO
	prices
VALUES
	('apple', 4),
	('banana', 25),
	('orange', 11),
	('kiwi', 20)

When used on the num column, MAX will return the largest value.

SELECT
	MAX(price)
FROM
	prices;

Returns: 25

MAX can also work on text columns by returning the text row with the characters that are last in the lexicographic order.

SELECT
	MAX(item)
FROM
	prices;

Returns: orange
