i want update id 2, "sprite" price 2.50 usd. normally, need run trigger update audit table. audit table need register id of product. need know updated row's id 2...

is there similar in sql?

you can refer id column using either new.id or old.id long id column not change.

generally spoken, alias new can current value of updated column , old obtain value column had before update performed.

create trigger au_product_table     after update on product_table     each row     update audit         set product_id = new.id         your_condition;
