Create a trigger named trg_cust_charge that will automatically update the CUSTOMER table’s CUS_BALANCE when a new CHARTER row is added. Use the CHARTER table’s CHAR_TOT_CHG as the update source (Assume that all charter charges are charged to the customer balance.) In addition to the CHAR_TOT_CHG, add a $5 service charge for every 50 miles flown.

Question

Please create this two trigger and write down as Mysql statement

  • Create a trigger named trg_charter_time that will automatically update 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. The meaning for the AIRCRAFT table columns are as follows: AC_TTAF: Total time on the air frame (before maintenance)

AC_TTEL: Total time on the left engine (before maintenance, also track single engine)

AC_TTER: Total time on the right engine (before maintenance)

 

So in the trigger, you need to decrease all of them by the number of CHAR_HOUR_FLOWN
