This CREATE TABLE statement creates a queue table named shopping_cart:

     CREATE SET TABLE shopping_cart, QUEUE (
       cart_qits  TIMESTAMP(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6),
       product_id INTEGER,
       quantity   INTEGER )
   PRIMARY INDEX (product_id);

This SELECT AND CONSUME statement returns all the columns of the row with the oldest value in the cart_qits column of the shopping_cart table:
