[sinha.ashish]

void VistaMedia::search()
{    
    QString searchText=searchTextLineEdit->text();
    QSqlQuery query;
    query.prepare("SELECT * FROM mediadetails WHERE title LIKE  %:title% ");
    query.bindValue(":title",searchText);
    query.exec();
    while(query.next())
    listWidget->addItem(query.value(1).toString());
                QSqlError e=query.lastError () ;
    QMessageBox::information(this,"problem",e.text());
}

void VistaMedia::search()
{    
    QString searchText=searchTextLineEdit->text();
    QSqlQuery query;
    query.prepare("SELECT * FROM mediadetails WHERE title LIKE  %:title% ");
    query.bindValue(":title",searchText);
    query.exec();
    while(query.next())
    listWidget->addItem(query.value(1).toString());
                QSqlError e=query.lastError () ;
    QMessageBox::information(this,"problem",e.text());
}

To copy to clipboard, switch view to plain text mode 

above function shows error message box as "syntax error near %" after calling. Help me to write the correct syntax or anyclues for searching using wildcards!!!!!!!!

The query should be:
SELECT * FROM mediadetails WHERE title LIKE '%:title%'

...and better don't use the asterisk in conjunction with query.value(1). If You later change your table layout, the code will behave incorrect. Use "SELECT `myColumnNameWhichIWant`..." and query.value(0) in your case.

void VistaMedia::search()
{
QString serachText=searchTextLineEdit->text().trimmed();
int noOfItems=listWidget->count();
while(noOfItems>0)
{
if(!(listWidget->item(noOfItems-1)->text().contains(mname, Qt::CaseInsensitive)))
{
listWidget->removeItemWidget ( listWidget->item(noOfItems-1));
delete listWidget->item(noOfItems-1);
}
l--;
}
}


I have solved my problem in another way ,just using listwidget's functions,without using query.its fast and better.Thanks to all replies ....
