I have been busy with work before I wrote it, taking advantage of the vacation, and the friends around me want to try the latest version of Navicat Premium 15. The official website says that the latest version of Navicat Premium has many new features, and the blogger is honest , I also want to experience it, so in view of this, I posted my own articles for your reference. Since the blogger still advocates the willingness to maintain the original version, if the financial strength allows, I still hope that you can download it from the official website, hehe ~~, OK, let’s not talk too much nonsense, just go to the tutorial.
