Is there a tool other than ij to look into a local derby database (folder)?

I use DBeaver Community Edition (free and open source).

When comparing DBeaver CE 6.0.2 (2019-04-08) against SQuirreL 3.9.1 (2019-02-24) I noticed that SQuirreL does not show some database objects (eg. sequences).

DBeaver supports intellisense / auto-completion, updating table rows in-place (ie. "select for update"), and can globally apply filters on schemas and catalogs in connection settings (eg. exclude SYS schemas from the object tree display). It can also run pre- and post-connection scripts (handy for initialising an ij session with preferences eg. protocols).

I simply use NetBeans IDE (Services -> Databases) to connect to my local or remote derby databases.

You can also create new derby databases there.

Squirrel SQL can connect to an Apache Derby database. Getting Started using the SQuirreL SQL Client
