What SQLTools is

SQLTools is a free Windows desktop frontend for Oracle databases, combining a text editor, SQL console, object browser, formatter, and query utilities. Its data grid supports pivoting, range selection, copying, exporting, and dragging results into the editor. The Object List browses objects by schema and type and offers maintenance actions such as compiling multiple packages. Quick Query and Quick Count generate queries for a table or for a table resolved from an alias under the cursor. SQLTools is portable, requiring no installation and allowing copies on a USB stick. It is developed and tested on Windows 10 and stated to be compatible with Windows 7 and Windows 11, with 32-bit and 64-bit builds. A properly installed Oracle Client is required, and its architecture must match the SQLTools build; Oracle Client 12c and 19c are listed. Supported databases are Oracle 11g, 12c, and 19c, while 10g and 21c may work but are untested. The software is released under GNU GPL version 3 and is free of charge.
