mysql create trigger failed

enter:

CREATE TRIGGER newproducts AFTER INSERT ON products
    -> FOR EACH ROW SELECT 'Product added';

output:

ERROR 1415 (0A000): Not allowed to return a result set from a trigger

Reason: Triggers cannot use select to set variable results, which will return the result set, if the trigger (TRIGGER) is to be written in the way of into. Such as: SELECT 'Product added
';
change to:
select 'Product added' into @args;
