    I found we use SQL triggers a bit too much... 336 triggers on 1450 tables... (~23%)

    We got you beat. 247 triggers on 741 tables, exactly 1/3, although not intentional.

      I avoid them as triggers too easily lend themselves to database-vendor specific code.

        Actually some of the triggers are there to log data changes (on important tables)... Others are for data integrity... And others are for sync with externals...

          My former bosses have about 10 - 15 triggers on each and every table, some of them thousands of lines long. A nightmare. Especially after that experience: 0.0 triggers per table and not a single trigger more.

          I have lived with several Zen masters - all of them were cats.

            That sounds awful... Our triggers are short (sometimes 2-3 triggers on the same event, just because they all do something else)...

              The major part of the application logic took place in those triggers. Guess why I run out of job interviews when I hear 'Access' or ' Former Acess project that has ben ported to xxx'.

                            Zero. Though I may have written one about ten years ago. Only as a convenience for debugging. It was not vital to the system.

                              Surely that would affect performance to have that many? Most DBs I've worked on tend to not have more than a few tops.

                                Even worse. Access guys in charge. I must have offended him when I looked at that stuff and asked him what this particular form of insanity is called.

                                  :sigh: I hate triggers spit Development - 0 triggers UAT and Production 3 triggers on each of the master tables. I have a script that uses a configuration table to create and remove audit triggers on selected tables for each database. As we have approx 15 databases, any 3 of which will be deployed to production in any month this script is a life saver.

                                        It's the 'We don't need any architecture or documentation, and you are a fool for asking.' mentality that I don't like. They can keep on doing their stuff as long as they like (or until their customers finally have enough), but I will not work like that again.

                                          It's the 'We don't need any architecture or documentation, and you are a fool for asking.' mentality that I don't like.

                                          Oh, indeed! Fortunately this project was written originally (entirely in Access) by someone who actually had a clue, and the 'owner' who understands the business (and is also a dev) has worked on it - so I have been able to gradually document the entire setup, what things represent and do etc. Whilst it's still very much a work in progress, I've been able to add all sorts of functionality, but I've discovered nearly 60 GOTCHAs (so far!) when moving from Jet to SQL - documented hereabouts somewhere. The trickiest new feature was CRM functionality as the data had to be imported from another (commercial) system where ALL information (used in tens, if hundreds) of different views was all stored in ONE huge SQL table and extracted by the most complicated series of inner joins and table aliases that I have ever seen. The person who wrote that must have been on acid! "Normalisation - never heard of it!" Definitely write only code...
