Stable release

TypeDatabase administration tool

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.[1]

SQuirreL SQL Client is free as open source software that is distributed under the GNU Lesser General Public License.

Feature summary[edit]

  • Object Tree allows for browsing database objects such as catalogs, schemas, tables, triggers, views, sequences, procedures, UDTs, etc.
  • The SQL Editor, based on RSyntaxTextArea by fifesoft.com, provides syntax highlighting. It can open, create, save and execute files containing SQL statements.
  • SQuirreL supports simultaneous sessions with multiple databases. This allows comparing data and sharing SQL statements between databases.[2]
  • 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 - see SQuirreL SQL Client Plugin API for more details)
  • 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.[3]
  • Bookmarks - user-defined code templates. SQuirreL comes with predefined example bookmarks for the most common SQL and DDL statements.[3]


The SQuirreL SQL project was developed by a team of Java developers around the world and led by Colin Bell. It has been hosted as a SourceForge project since 2001, and is still being developed today.[when?]
