Hello i have a problem i looked a lot but did not find a exact solution. I have a
QStandardItemModel to which i am adding data which is present in the QVectors which is retrieved from the data base and i set this data Model into the tableView.

This is how i am displaying the data from a data base to QTableView
Qt Code: 
  2. 		  model1 = new QStandardItemModel();
  3. 	             for(int i=0;i< temptagidnames.count(); i++)
  4. 					 {
  5.                  		QStandardItem *item = new QStandardItem(temptagidnames.at(i));
  6. 						model1->setItem(i, 0, item);
  7.                       		     	 }
  8.               model1->setHeaderData(0, Qt::Horizontal, tr("TAG ID"));
  9. 	      model1->setHeaderData(1, Qt::Horizontal, tr("Description"));
  10.                           tableView->setModel(model1);	
  11. 			  tableView->setAlternatingRowColors(true);
  12. 			  tableView->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
To copy to clipboard, switch view to plain text mode 

I wrote the below code to update the changes made in the QTableView into the sqlite db.

Qt Code: 
  2. 		  model1 = new QStandardItemModel();
  3.                   QSqlTableModel *model1;
  4. 		  model1 = new QSqlTableModel;
  5.  
  6. 		model1->setTable("tempchnames");
  7.         model1->setEditStrategy(QSqlTableModel::OnFieldChange);
  8. 		tableView->setColumnHidden(0, true);
  9.  
  10. 	             for(int i=0;i< temptagidnames.count(); i++)
  11. 					 {
  12.                  		QStandardItem *item = new QStandardItem(temptagidnames.at(i));
  13. 						model1->setItem(i, 0, item);
  14.                       		     	 }
  15.  
  16.                   model1->setHeaderData(0, Qt::Horizontal, tr("TAG ID"));
  17. 	          model1->setHeaderData(1, Qt::Horizontal, tr("Description"));
  18.  
  19.                           tableView->setModel(model1);	
  20. 			  tableView->setAlternatingRowColors(true);
  21. 			  tableView->setSizePolicy(QSizePolicy::Expanding,
To copy to clipboard, switch view to plain text mode 

But i get errors like, I am not able to know how i can link QStandardItemModel Model and QSqlTableModel so that the changes i make in the QTableView are reflected in the data base immediately.
error C2371: 'model1' : redefinition; different basic types
error C2039: 'setTable' : is not a member of 'QStandardItemModel'
i am stuck with this problem past 2 days,.
Thank you
