推荐答案

我个人也遇到了这个问题. Netbeans有时在处理MySQL时遇到问题.我建议您下载MySQL Community Server和MySQL Workbench并使用它们来运行数据库.它效率更高，并且可以让您更好地控制数据库.

I've personally had this problem too. Netbeans sometimes has problems dealing with MySQL. I would suggest you download MySQL Community Server and MySQL Workbench and use those to run your database. It's much more efficient and gives you more control over your database.
