Question

This does not work:

CREATE OR REPLACE TRIGGER trg_char_hours
AFTER INSERT ON CHARTER
FOR EACH ROW
BEGIN
UPDATE AIRCRAFT
SET
AC_TTAF = AC_TTAF + NEW.CHAR_HOURS_FLOWN,
AC_TTEL = AC_TTEL + NEW.CHAR_HOURS_FLOWN,
AC_TTER = AC_TTER + NEW.CHAR_HOURS_FLOWN
WHERE AIRCRAFT.AC_NUMBER = NEW.AC_NUMBER;
END;
I get the following error:
 
ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'TRIGGER trg_char_hours AFTER INSERT ON CHARTER FOR EACH ROW BEGIN UPDATE AIRCRAF' at line 1
 
Here is the original question:
 

Create a trigger named trg_char_hours that automatically updates the AIRCRAFT table when a new CHARTER row is added. Use the CHARTER table’s CHAR_HOURS_FLOWN to update the AIRCRAFT table’s AC_TTAF, AC_TTEL, and AC_TTER values.

(Hint: use temp values, as the INSERT event does not accept the OLD keyword.)
