# 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.
|
||||
|
||||
|
||||
|
||||
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`__*__.
|
||||
|
||||
__*__ How to install `msodbcsql` - [Installing the Microsoft ODBC Driver for SQL Server on Linux and macOS](https://docs.microsoft.com/en-us/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server).
