# 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.
|
||||
|
||||
![](screenshot.png)
|
||||
|
||||
The program was tested on:
|
||||
* client: Windows 10, Qt 5.9.1,
|
||||
* servers: MySQL Server 5.5.57, Microsoft SQL Server 2008 R2 SP3.
