I can't connect to my MySQL database [Solved]

BadCombination

Hi, I'm learning to program in Qt, but I can't connect with my database.

I don't find my error, Qt Creator says the variable type is incomplete.

Have you included sql at your pro file? Please also make sure that your Qt MySQL driver is installed. To install it on fedora you should run something like:
@yum install qt-mysql@

Did you include?

@
#include <QSqlDatabase>
@

In theory this is enough:

@
#include <QtSql>
...
QSqlDatabase db = QSqlDatabase::addDatabase( "QMYSQL" );
db.setHostName( "localhost" );
db.setDatabaseName( "yadayada" );
db.setUserName( "yadayada" );
db.setPassword( "yadayada" );

if( !db.open() )
{
qDebug() << db.lastError();
qFatal( "Failed to connect." );
}

qDebug( "Connected!" );
...
@

In *.pro file:
@
QT += sql
@

Anyway your error message is a typical text when you forget some include file, in this case:
#include <QSqlDatabase>

Thanks to everyone, I can run with the database including this code in the header of main.cpp.

@#include <QtSql/QSqlDatabase>@

Macro

Jus try including Qt += sql in the .pro file and try...
