HeidiSQL
HeidiSQL is a graphical interface for managing MariaDB or MySQL servers, Microsoft SQL databases, PostgreSQL, SQLite, Interbase or Firebird. "Heidi" lets you browse and edit data, create and edit tables, views, procedures, triggers and scheduled events. Also, you can export structure and data, either to SQL file, clipboard or to other servers. Read about features or see some screenshots.
Need help?
Look at the online help page to learn how to use HeidiSQL. The forum is meant to ask questions. The issue tracker is the place to report bugs or request new features.
Building
For compiling on platforms other than Windows, look at the lazarus branch.
Delphi 12.1 is required for building HeidiSQL for Windows. Older Delphi versions will most likely fail; newer Delphi versions may work or fail. Unfortunately, Lazarus or one
of the other free compilers cannot currently compile HeidiSQL.
Once Delphi is installed, you need to load the SynEdit project from the components folder. Build both run-time and design-time packages. Install the
design-time package. Do the same for the VirtualTree component project.
Second you need install madExcept.
Third compile *.rc files:

if updater.rc and updater.exe are not exists. you can copy them from updater64.rc and updater64.exe.

Afterwards, load the HeidiSQL project from the packages folder.
Translation
If you'd like to contribute by translating HeidiSQL into your mother tongue, you need to register at
Transifex, and join an existing language or request a
new one.

HeidiSQL is presented as a lightweight graphical interface designed for the comprehensive management of a diverse set of relational database servers. It functions as a client that allows users to interact directly with numerous database systems, including MariaDB, MySQL, Microsoft SQL Server, PostgreSQL, SQLite, Interbase, and Firebird. The scope of its functionality encompasses detailed data interaction, providing tools for browsing and editing data, managing database schema elements such as tables, views, stored procedures, triggers, and scheduled events. Furthermore, the application supports the export of both database structure and associated data, allowing users to transfer this information into various formats, such as SQL files or the clipboard, or export it to other database servers.

The underlying development of HeidiSQL was executed using the Delphi and Lazarus/FreePascal programming languages. The instructions provided outline the specific requirements for compiling the application, noting that building for Windows necessitates Delphi 12.1. The compilation process involves a multi-step procedure including loading specific project files from the components folder, building run-time and design-time packages, installing madExcept, and compiling specific resource files designated by extensions like rc files. This technical process demonstrates the reliance on specific compiler environments and package management systems inherent in the project's architecture.

Regarding the development and community interaction, the project is licensed under the GPL-2.0 license. The repository emphasizes a specific approach to contributions, stating that pull requests are primarily accepted for bugfixes rather than new feature additions. Developers interested in contributing to the project are directed to follow specific procedures, including registering on Transifex for translation efforts or contacting the project maintainer for developer membership. The project has demonstrated significant community engagement, indicated by a substantial number of stars and forks, and is indexed across various technical topics related to database management, programming languages like Delphi and FreePascal, and various database systems.
