Topic: The help in trigger writing.
Hello, your help is very necessary. For examination asked to make the trigger which at change in label VR_DOG in column DATA_OKON at change (adding/removal) of date automatically in table VR_RAB in column STATUS_RAB does following records: if there is a date "is dismissed" if there is no date - "works". Wrote the trigger, but it does not work. I do not catch up in what with business, therefore I ask about the help!
