SQL Workbench/J is a versatile and free SQL query tool that operates independently of any specific database management system and is compatible with various operating systems due to its Java foundation. It is designed to execute SQL scripts, whether interactively or in batch mode, while also offering robust import and export functionalities. Although it does not prioritize graphical query building or complex database administration tasks, it includes a powerful export command that allows users to generate text files, XML, HTML, or SQL formats, including support for BLOB data. Users can easily export all tables from a database to a designated directory using a single command, and the export files can be compressed during the process. The tool also supports efficient import of text, XML, and spreadsheet files, enabling users to bring in sets of files, including compressed versions, from a directory with one command. Additionally, it intelligently detects foreign key constraints to ensure proper data insertion order. Users can also compare two database schemas to identify differences, and the tool provides the capability to convert XML output into the appropriate SQL ALTER statements using XSLT, enhancing its functionality even further. Overall, SQL Workbench/J serves as a comprehensive solution for users seeking a straightforward approach to managing SQL queries across various platforms.
