C++ (Cpp) DataMap::isEmpty Examples

Example #1

File: sqlitemgr.cpp Project: TheCodingArt/QTester

bool SQLiteMgr::sessionConfigurate(const DataMap &data)
{
    QSqlQuery query;
    if( ! data.isEmpty() )
    {
        QString query_string;
        for (auto i = 0; i < data.count(); i++) /// \warning TODO: БЫЛО <= ПРОВЕРИТЬ
        {
            query_string += "PRAGMA" + data.keys().at(i) + " = " + data.values().at(i) + " \n";
        }

        return query.exec(query_string);
    }
    return false;
