Hi All

I want to use QSql in my application to call History..

I have gone through the qt examples and documents and i tried small examples based the examples given with Sdk.

I want to store call history..

In examples i did like
Qt Code: 
  1. QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
  2.     db.setDatabaseName(":memory:");
  3.     if (!db.open()) {
  4.                return;
  5.     }
  6.  QSqlQuery query;
  7.     //query.exec("create table yuvaraj ( id int , name varchar(20000))");
  8.     query.exec("insert into yuvaraj values(1000,'"+QString(str)+"')");
  9.     model = new QSqlRelationalTableModel(this);
  10.     model->setTable("yuvaraj");
  11.     model->select();
  12.  QMessageBox::information(0,"1",QString("yuvarj"));
  13.     mapper = new QDataWidgetMapper(this);
  14.     mapper->setModel(model);
  15.     mapper->addMapping(ui->textBrowser, model->fieldIndex("name"));
  16.     QMessageBox::information(0,"2",QString("yuvarj"));
  17.     mapper->toFirst();
To copy to clipboard, switch view to plain text mode 

there isan another way to create own database


Qt Code: 
  1. QSqlDatabase db = QSqlDatabase::addDatabase("QPSQL");
  2.      db.setHostName("customer");
  3.      db.setDatabaseName("customdb");
  4.      db.setUserName("yuvaraj");
  5.      db.setPassword("yuvaraj");
  6.      bool ok = db.open();
To copy to clipboard, switch view to plain text mode 

i have one doubt .which method i have to use.if declare this code at constructor every time database and table is creating..

Where can i find good example based one QSql apart from examples.

Can you please suggest me

Thanks
