how to use database value in the variable

Code:

---

QString timess;
    QSqlQuery qry;
    qry.prepare("SELECT FROM test WHERE time = '"+timess+"'");
   if (qry.exec()){
        ui->time->setText(timess);
        qDebug("timess");
   };

---

This is my code. after I Run ui didn't show anything.

I create timess with qstring and store the time value from database(SQLite) into it's.
But in the time ui (QLable) didn't show anything after I run the process.
:confused:

1. SQL query is incorrect - You must indicate what you want select.
2. Read about QSqlQuery::next and QSqlQuery::value.
