SQL Workbench/J

SQL Workbench/J is a cross‑platform SQL query tool written in Java, allowing it to run on any operating system with a Java Runtime Environment. It supports a wide range of database management systems, such as PostgreSQL, Oracle, DB2, HSQLDB, and others, without being tied to a specific DBMS. The tool focuses on executing SQL scripts, both interactively and in batch mode, and provides extensive import and export capabilities. Users can edit, insert, and delete data directly within query results, and export tables to formats like CSV, XML, HTML, or SQL, with optional on‑the‑fly compression. Import functions handle text, XML, and spreadsheet files, and the software is aimed at developers and database administrators who need a lightweight, command‑oriented environment rather than a full‑featured IDE.
