The SQuirreL SQL Client is a database administration tool. It uses JDBC to allow users to explore and interact with databases via a JDBC driver. It provides an editor that offers code completion and syntax highlighting for standard SQL. It also provides a plugin architecture that allows plugin writers to modify much of the application's behavior to provide database-specific functionality or features that are database-independent. As this desktop application is written entirely in Java with Swing UI components, it should run on any platform that has a JVM.3
SQuirreL SQL Client is free as open source software that is distributed under the GNU Lesser General Public License.
Feature summary
- Object Tree allows for browsing database objects such as catalogs, schemas, tables, triggers, views, sequences, procedures, UDTs, etc.

- SQuirreL supports simultaneous sessions with multiple databases. This allows comparing data and sharing SQL statements between databases.4
- SQuirreL runs on any platform that has a JVM.
- A plugin architecture facilitates database vendor-specific extensions (information or actions not available using standard JDBC)
- Translations for the user interface exist in: (Bulgarian, Brazilian Portuguese, Chinese, Czech, French, German, Italian, Japanese, Polish, Spanish, Russian).
- Graph capabilities can generate charts showing table relationships.5
- Bookmarks - user-defined code templates. SQuirreL comes with predefined example bookmarks for the most common SQL and DDL statements.5
