If you want to have multiple database connections, name them when calling QSqlDatabase::addDatabase( "name" ) and then retreive them via QSqlDatabase::database( "name" ).
If you use only single connection then use QSqlDatabase::addDatabase() only once and later retreive it via QSqlDatabase::database().

Read manual for QSqlDatabase::database() and QSqlDatabase::addDatabase() for more info.
