Hi,
No matter how i read the manual i can't understand it. :(
Here is what i would like to do.
for example i have
table: classes
column: classno,...,schedule_count
table: schedules
column: classno,time
I would like to create a trigger that everytime there is an insert or delete in schedules
classes.schedule_count will be updated with number of schedules entered in schedules for that particular class. this way i could track the number of schedules for that particular class without counting the schedules.
how do i implement it?
thank you,
oscar
