Re: insert QString to Sqlite encoding

sorry, I click on "Quick Reply" and thought it would show with the reply Smiley Wink


I mean where is the question Incogruous said: "Dude! I think a saw a similar question in the SQLite3 users group. The OP was asking about SQLite3 locale compatabilty with his/her machine.  I suggest to try that group as well, they just might have the answer. Best wishes"

Re: insert QString to Sqlite encoding

As i can insert and retrieve the test string without any issue (and you seem to be able to do that as well) the error is most likely not with sqllite.

I would suggest to test your code step by step and check where it fails.
I don't have a web service returning special characters, so you'll have to test that yourself.

Re: insert QString to Sqlite encoding

I have just spent a few days struggling with XML encoding issues in my desktop Rainmeter plugin, and I can confirm it can create a host of tricky problems when dealing with foreign languages.


Have you tried using PRAGMA ENCODING="UTF-8"? It is possible this will only work if you specify it while the db is being created though, so YYMV.


Also, this thread goes into great detail about this issue, although it is talking about a legacy BBOS version. That said, it could be useful.

I've been developing for BB10 since last year, but I'm new in this forum so hi to everyone!


I have a problem saving data to Sqlite. I read a xml feed encoding in utf-8 with portuguese characters, I show all strings ok but when I insert them into database encoding fails. Here is my code:


once I haver received xml

void updater(QVariantMap responseData) {
    QVariantList championshipsList = responseData["Campeonato"].toList();
    for(int i = 0; i<championshipsList.length(); i++) {
        QVariantMap auxChampionship = championshipsList.at(i).toMap();
        Championship championship;
        championship.id = auxChampionship["Id"].toString().trimmed();
        championship.name = auxChampionship["Nome"].toString().trimmed();
        //at this point, name show right! ex: "Seleção Brasileira"
debug("Championship ID:"+championship.id+" Name:"+championship.name); if(!_databaseManager->existsChampionship(championship)) _databaseManager->insertChampionship(championship); else _databaseManager->updateChampionship(championship); } }


and insert/update database:

bool DataBaseManager::updateChampionship(Championship championship) {
    QString query("UPDATE championships SET 'name' = :name WHERE id = :id;");
    QVariantList l;
    l << championship.name << championship.id;
        DataAccessReply reply = _sqlconnection->executeAndWait(query, l);
        if (reply.hasError()) {
            gerror(QString("SQL Error: %1").arg(reply.errorMessage()));
            gerror("Query: " + query);
            return false;
        } else {
//SqlConnection *_sqlconnection in .hpp _sqlconnection->endTransaction(reply.id()); //info("Championship " + championship.name + "-" + championship.name + " inserted into database."); } return true; }


all data stored in database have wrong encoding (like "Seleção Brasileira"). 

I don't know what happen, because if I put "name" by constant string like:


championship.name = QString::fromUtf8("Seleção Brasileira");

 it works fine!


anyone knows how to fix it?
