将VariantMap添加到数据库

insertRecord(const QVariantMap &trans)
{
        bool ret = false;
        if(trans.isEmpty())
        {

        }

        while(iter != trans.constEnd()){
                keys +=i.key();  #保存字段
                keys += ", ";
                v += "?,";  保存值
                list << i.value();  保存值
                ++iter;
        }
