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.
Compiled Windows and Linux applications can be downloaded from Releases.
The program was tested on:
- 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 (Qt driver plugins as well as system drivers) can be found in Qt Documentation. MSSQL is handled by the ODBC driver.
Windows 10
- Both Qt SQL driver plugins (QMYSQL and QODBC) should be already bundled with Qt SDK.
- MySQL driver can be installed by placing
libmysql.dll
from C API for MySQL (mysqlclient) in the app working directory. - ODBC Driver Manager and SQL Server driver are built in; hence, no further installation is necessary. Alternatively, instead of SQL Server driver, one can use Microsoft ODBC Driver; see Microsoft Docs.
Ubuntu 16.04
Packages with Qt driver plugins and system SQL drivers:
- MySQL -
libqt5sql5-mysql
libmysqlclient20
, - ODBC (unixODBC Driver Manager and Microsoft ODBC Driver) -
