+# 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.
