  • RE: Stock Updation Trigger on multiple rows deletion

    Generally speaking, triggers are a very bad place to implement business logic, because they make the code difficult to debug/follow. They are some sort of "hidden" code that is...

  • RE: update trigger get fields before and after update

    You'll want to match directly on id, then you can use CHECKSUM across the other columns. Remember to always think set-based when possible, to get max benefits from SQL's processing.

    Another benefit to using the calendar table rather than the Select DateAdd, performance is much better when used for filtering/grouping.

  • RE: Difference between purchase dates in days

    Do you want each individual date difference or do you just want an average days' difference between orders? The latter is much less work to calc :-).

    As long as the file name is the only YYYYMMDDHHMMSS string in the file, I think you can just check for that pattern:

    Prior to updating the table, put the username in a known place, and the trigger can retrieve it from there and use it.
