问题 I'm using Derby ij to look into my local Apache Derby database. It's just a folder and I connect to it like this: connect 'jdbc:derby:C:\Users\Torben\MyDatabase' USER 'me' PASSWORD 'secret'; It works, but I don't really like to look into the database in the console. Is there another tool for this? The best would be something with a GUI. 回答1: Squirrel SQL can connect to an Apache Derby database.

I would like to use Derby from apache in order to include database management on a desktop application that I'm currently developing. Unfortunately I figured out that they have stopped developing this plugin and all the tutorials I've read online refer to this plugin.
