HeidiSQL

This is a community package of HeidiSQL, maintained independently. It repackages the official upstream build unmodified.

HeidiSQL is a desktop client for everyday database work, in development since 2002. It connects to MariaDB, MySQL, PostgreSQL, Microsoft SQL Server and SQLite from one window: browse and edit data in a grid, design and refactor tables, write and save queries, and fix things on a live server without leaving the tool.

• Data grid with in-place editing, filtering, and quick insert, update and delete
• SQL editor with syntax highlighting, completion and query history
• Table, view, procedure, trigger and user editors; export as SQL, CSV, HTML, XML or JSON
• Copy tables and whole databases between servers, and compare their structures
• Connect over TCP/IP, a named socket, or an SSH tunnel

The Linux build is upstream's Lazarus/FreePascal port, packaged here from the official qt6 release. Support for Microsoft SQL Server on Linux goes through FreeTDS and upstream describes it as still maturing.

Sessions and settings are stored in this application's own configuration directory, and databases are reached over the network. Files you open or export — SQLite databases, .sql scripts, CSV exports — are picked through the file-chooser dialog.

A few capabilities are not granted by default; enable the ones you need with "flatpak override":

• Keep a local SQLite database or .sql script reachable across restarts, without picking it in the dialog each time: flatpak override --user --filesystem=/path/to/dir com.heidisql.HeidiSQL
• Reuse your existing host SSH keys for the SSH-tunnel feature: flatpak override --user --filesystem=~/.ssh:ro com.heidisql.HeidiSQL

New upstream releases are picked up by FlatPark and delivered through "flatpak update".
