SQuirreL SQL Client is a graphical Java program that will allow you to view the structure of a JDBC compliant database, browse the data in tables, issue SQL commands etc, see Introduction. The minimum version of Java supported is 1.6.x as of SQuirreL version 3.0. See the Old Versions page for versions of SQuirreL that will work with older versions of Java.

SQuirreL's functionality can be extended through the use of plugins. A short introduction can be found here. To see the change history (including changes not yet released) click here. For a more detailed introduction see the English or German of our paper on SQuirreL.

Susan Cline graciously took the time to document the steps she followed to setup an Apache Derby database from scratch and use the SQuirreL SQL Client to explore it. Quite some time ago Kulvir Singh Bhogal wrote a great tutorial on SQuirreL and published it at the IBM developerWorks site. He has kindly allowed us to mirror it locally. The tutorial is not really up to date but especially for doing the first steps it is still of help.
