Examples | ARRAY_MAX Function | Teradata Vantage - Example: Querying a 1-D ARRAY Data Type and Table using ARRAY_MAX - Teradata Vantage - Analytics Database

Consider the following 1-D ARRAY data type and table.

CREATE TYPE item_price AS DECIMAL(7,2) ARRAY[20];
CREATE TABLE inventory (itemkind INTEGER,
                        regular_price item_price,
                        sale_price item_price);

The following query returns an element value, which is the maximum of all the element values in the regular_price array.

SELECT ARRAY_MAX(regular_price) FROM inventory;

The following is the same query using method-style syntax.

SELECT regular_price.ARRAY_MAX() FROM inventory;

The following query returns an element value, which is the maximum of the element values within the specified scope of the regular_price array.

SELECT ARRAY_MAX(regular_price, 5, 10)FROM inventory;
