  I have code on an update trigger that sends an email when a record is changed. Is there an easy way to identify which column(s) would have been changed?

  ANy help would be appreciated.

  Thanks,

  vmon

  There are several ways and I'm not sure any are all that great. Take a look in BOL for COLUMNS_UPDATED. That is one of the ways to determine which columns have changed.

  You can use IF UPDATE or COLUMNS_UPDATED, see Programming DML Triggers for details and examples.
