Can't use sqlite if Qt development Framework not installed

[wirasto]

I don't understand why this code not executed when Qt development Framework not installed.

....
....
 
extern QSqlDatabase dbFav;
 
void DB::init() // this is static void
{
    QDir dir;
    if (!dir.exists(CONF_PATH))
        dir.mkpath(CONF_PATH);
 
    //favorite
    dbFav=QSqlDatabase::addDatabase("QSQLITE", "favorite");
    dbFav.setDatabaseName(QString("%1/favorite.%2").arg(CONF_PATH).arg(DB_SUFFIX));
    dbFav.open();
    QStringList tablesFav = dbFav.tables();
    QSqlQuery queryFav(dbFav);
    if (!tablesFav.contains("folder", Qt::CaseInsensitive)) {
        queryFav.exec("CREATE TABLE folder ("
                        "id integer primary key,"
                        "nama text not null,"
                        "id_induk int not null,"
                        "unique(nama, id_induk)"
                        ")");
    }
}

....
....

extern QSqlDatabase dbFav;

void DB::init() // this is static void
{
    QDir dir;
    if (!dir.exists(CONF_PATH))
        dir.mkpath(CONF_PATH);

    //favorite
    dbFav=QSqlDatabase::addDatabase("QSQLITE", "favorite");
    dbFav.setDatabaseName(QString("%1/favorite.%2").arg(CONF_PATH).arg(DB_SUFFIX));
    dbFav.open();
    QStringList tablesFav = dbFav.tables();
    QSqlQuery queryFav(dbFav);
    if (!tablesFav.contains("folder", Qt::CaseInsensitive)) {
        queryFav.exec("CREATE TABLE folder ("
                        "id integer primary key,"
                        "nama text not null,"
                        "id_induk int not null,"
                        "unique(nama, id_induk)"
                        ")");
    }
}

Have you deployed the Qt Sqlite database plugin with your executable? Search this forum... this problem is addressed nearly every day.

Yes it does, but you need to put the file in the correct location: http://www.qtcentre.org/threads/3712...819#post170819
