  1. NOT IN — не противоположность IN: что в запросе ломает один NULL

    В SQL самые опасные ошибки часто выглядят как рабочие запросы. Они не падают, не ругаются на синтаксис и не подсвечиваются в IDE — просто возвращают пустоту там, где должны быть данные. В этой статье разберём классическую ловушку NOT IN : почему один NULL в подзапросе может «отравить» всю выборку, чем IN на самом деле отличается от NOT IN и почему в таких случаях безопаснее писать через NOT EXISTS .

    Forty-one years ago today, I stepped onto a plane in Halifax, Nova Scotia, heading toward a national office in Toronto, Ontario, and a future that didn't yet have a name.

    I was a Chartered Accountant by trade, but my heart was already in the "pipes"—the emerging, messy world of computer connectivity. For three years, I had already immersed myself deep into the opportunities that came from the online world, understanding the power of global collaboration, online research, knowledge acceleration, and disruptive ideas. In my heart and in my mind, I just knew that something big was on the way, and I wanted to be a part of it.

    41 years on, I know I did the right thing.

    Many times in your life, you will need to confront similar big decisions. Should you make the big, bold leap? Should you take the daring jump into the unknown? Can you really hold your breath, close your eyes, take the plunge into tomorrow, and hope for the best?

    If you don't, you might end up regretting not doing the most important thing you should have done.

    Never put yourself in that situation.

    The greatest risk you will ever take is the risk of staying where you are when you know you were meant for what’s next.

    Don't ask what happens if you fail.

    Ask what happens if you never try at all.
