# Qt SQL Example
An exemplary Qt app that connects to SQL server and displays a table from a database. The program was made for educational purposes.
An exemplary [Qt](https://www.qt.io/) app that connects to SQL server and displays a table from a database. The program was made for educational purposes.
![](screenshot.png)
The program was tested on:
* client: Windows 10, Qt 5.9.1,
* clients: Windows 10 with Qt 5.9.1, Ubuntu 16.04 with Qt 5.5.1,
* servers: MySQL Server 5.5.57, Microsoft SQL Server 2008 R2 SP3.
## Client config
The program reads `config.ini` on startup. The file must be located in the app working directory.
## SQL database drivers
A comprehensive discussion about SQL database drivers can be found in [Qt Documentation](https://doc.qt.io/qt-5/sql-driver.html).
### Windows 10
* Both Qt driver plugins should be already bundled with Qt SDK.
* System ODBC driver should be already bundled with Windows.
* System MySQL driver can be *installed* by placing `libmysql.dll` from [C API for MySQL (mysqlclient)](https://dev.mysql.com/downloads/connector/c/) in the app working directory.
### Ubuntu 16.04
Packages with Qt driver plugins and system SQL manager with drivers:
* MySQL - `libqt5sql5-mysql` `libmysqlclient20`,
* MSSQL/ODBC - `libqt5sql5-odbc` `libodbc1` `odbcinst` `unixodbc` `msodbcsql`__*__.
