The forum uses a table named Opinion.The records have a ID, fatherID, IsFather.I have added a new field "threadID".The records now have a ID, fatherID, IsFather, threadID.I want to store in threadID the root entry of the thread - this is the first ID the first (ancient father) message in a topic gets.I want to recognise all the relevant records from each record in a discussion. All threads will have the uniq ID.I think of using a triger but I am new to that.1. if a record is updated and ID = ThreadID and ISfather=12. update all child records SET ThreadID = Father's.ThreadIDor 1. if a record is updated ThreadID = 02. update all child records SET ThreadID = Father's.ThreadIDthis will cause a recursive update to all child records.ThanksDror" |
