Hello friends i have a small problem in retrieving data from a sql database. I am able to save data into the table and even retrieve it in other parts of my program. But in this place i am having a sql error .

Qt Code: 
  1. for(int i=0; i <dbrowcount.count();i++)
  2. 	{
  3. 		if((dbrowcount.at(i)>0)&&(dbrowcount.at(i)<33))
  4. 		{
  5. 			deletenum = dbrowcount.at(i);
  6. 			QSqlQuery sqp("SELECT Box1 FROM tempBulkdb rowid ="+ QString::number(deletenum));
  7. 		if(sqp.exec())
  8. 			  {
  9. 				 if (sqp.first())
  10. 				{
  11. 			     do
  12. 				  {
  13. 				   boxtempchn.push_back(sqp.value(0).toString());
  14. 				  } while(sqp.next());		  
  15. 				}
  16. 			  }
  17.  
  18. 			 qDebug()<< sqp.lastError().text(); 
  19.                          qDebug()<<boxtempchn;
  20. 		}

dbrowcount has the row number and the size of the list. I have 10 nested else if condition i have put only the first condition , i am testing the first condition only now.
i get a sql error. I don't know if i am doing any thing wrong.
This is the Sql Error i am getting.
Qt Code: 
  1. No query Unable to fetch row
