SQL data extraction error

fkaraokur

I have a query like this.

query.prepare("Select * from Liste WHERE id=?");
query.addBindValue(id_);
query.exec();

This query only returns 1 row of 4 columns. I checked this out.
I want to get the column values in this single row. The following procedure did not work. What should I do?

The following codes did not work. and it gives an error like this.

qDebug()<<query.value(1).toString();

QSqlQuery::value: not positioned on a valid record
""

You have to call QSqlQuery::next() as explained in the documentation.
