What is a row trigger?

Rating:

A row trigger defined for a table is fired for each row of the table, which is affected by the triggering statement. For example, if an UPDATE statement updates multiple rows of a table, a row trigger is fired once for each row affected by the UPDATE statement. If the triggering statement does not affect any row, the row trigger is not fired.

A row trigger is created by using the FOR EACH ROW option with the CREATE TRIGGER statement. Row triggers are useful if the code in the trigger action depends on the data provided by the triggering statement or affected rows.
