I'm not sure what you mean.


...
QString insertQuery = "insert into teacher(login_id,teacher_fname,teacher_lname)value s(" + ui.txtTeacherLogin->text() + "," + ui.txtTeacherFname->text() + "," + ui.txtTeacherLname->text() + ")";
...
QSqlQuery query(insertQuery);
if (!query.exec())
return;
...

or


QSqlQuery query;
query.prepare("insert into teacher(login_id,teacher_fname,teacher_lname) value s(?, ?, ?");
query.addBindValue(ui.txtTeacherLogin->text() );
query.addBindValue(ui.txtTeacherFname->text());
query.addBindValue(ui.txtTeacherLname->text());
if (!query.exec())
return;
