DBKnife: SQL editor for MySQL, PostgreSQL, SQL Server and SQLite

Works with

SQL editor: Completion of schemas, tables and columns, through aliases too. Formatting, find and replace, snippets. Run everything, the selection or the statement under the cursor.
Results you can edit: A fast grid with filter and sort, for hundreds of thousands of rows. Edit cells, add and delete rows: every change is shown as SQL before it is applied.
Execution plans: The plan of a query drawn as a diagram, to see why it is slow.
Table and object editors: Columns, indexes, foreign keys and triggers; views, procedures and functions. The table editor writes the smallest ALTER TABLE that makes the change.
Server administration: Server status with live charts, client sessions, server variables, users, roles and privileges, backup and restore.
Import and export: Results to CSV, JSON, SQL, HTML and Excel. CSV files and spreadsheets (xlsx, xls, ods) into a table.
Files as connections: SQLite databases and CSV files open like a server. A CSV file is edited as a table and saved in its own format.
Safe by default: UPDATE and DELETE without WHERE are refused. Production connections are marked on their tab. Unsaved edits and open transactions are confirmed before closing.

System	Download	Updates
macOS 12 or later	Apple Silicon, Intel	Automatic
Windows 10 and 11 beta	Microsoft Store, installer for x64	Automatic from the Store; with the installer, download the new version
Linux x64 beta	.deb for Debian and Ubuntu, AppImage for other distributions	Download the new version

macOS: open the .dmg and drag DBKnife to Applications. The app is signed and notarized by Apple, and updates itself.
Windows: the installer is not signed yet, so SmartScreen shows "Windows protected your PC": choose More info, then Run anyway. The Microsoft Store version has no warning.
Linux: make the AppImage executable before the first start (Properties, Allow executing as program, or chmod +x).
Beta: DBKnife is developed and used every day on macOS. The Windows and Linux versions come from the same code, but have been tried much less.

All versions and their changes are on the releases page. English and Italian are built in; other languages can be added as language packs.
