QSqlDatabase usage

[gboelter]

Perhaps you forgot to call Erpel::dbConnect()?

Hello jpn,

I prefer to call Erpel::dbConnect() when I need some datas from my database, not during starting the program.

Like this for example:

void Erpel::showKasseLayout()
{
    if (dbConnect(currentMandant))
    {
        QSqlQuery query;
        QString image;
 
        query.prepare("SELECT ID, Beschriftung, ArtikelNummer, Image, ToolTip, TimeStamp FROM kassenlayout");
 
        query.exec();
 
        if (query.isSelect())
            query.first();
 
       // more code follows here ....

void Erpel::showKasseLayout()
{
    if (dbConnect(currentMandant))
    {
        QSqlQuery query;
        QString image;

        query.prepare("SELECT ID, Beschriftung, ArtikelNummer, Image, ToolTip, TimeStamp FROM kassenlayout");

        query.exec();

        if (query.isSelect())
            query.first();

       // more code follows here ....

I think it's a little bit more code and a little bit more to do for the computer, but it's safer.

Is that correct?
