SQL Workbench/J is a DBMS-independent, cross-platform SQL query tool. It is written in Java and should run on any operating system that provides a Java Runtime Environment.

Its main focus is on running SQL scripts (either interactively or as a batch) and export/import features. Graphical query building or more advanced DBA tasks are not the focus and are not planned. It's not intended as a full blown "development IDE", but more as a powerful command line.

Current stable version: Build 129 (2022-10-23)
Current development build: 129.6 ( 2023-09-23)

Features:

• Edit, insert and delete data directly in the query result (Screenshot)
• Powerful export command to write text files (aka "CSV"), XML, HTML or SQL (including BLOB data).
  All user tables can be exported into a directory with a single command. Export files can be compressed "on-the-fly".
• Powerful text, XML and spreadsheet import. A set of files (including compressed files) can be imported from a directory with a single command. Foreign key constraints are detected to insert the data in the correct order
• Compare two database schemas for differences. The XML output can be transformed into the approriate SQL ALTER statements using XSLT
• Compare the data of two database and generate the necessary SQL statements to migrate one to the other.
• Supports running SQL scripts in batch mode
• Supports running in console mode (Screenshot)
• Search text in procedure, view and other sources using a SQL command or a GUI ( Screenshot 1 Screenshot 2)
• Search for data across all columns in all tables using a SQL command or a GUI (Screenshot 1 Screenshot 2)

• Select rows from related tables according to their foreign key definitions (Screenshot 1 Screenshot 2).
