Hi,

Please enclose your code in coding tags, without them it's really hard to read.

Are you sure that the server name is correct ?

my server name is=BARUN/BARUN

CODE:
@
int main(int argc, char *argv[])
{ QCoreApplication a(argc, argv);
QString servername=“BARUN//BARUN”;
QString dbname= “testDB”;

QSqlDatabase db=QSqlDatabase::addDatabase(“QODBC”); db.setConnectOptions(); QString dsn=QString(“DRIVER{SQL NATIVE CLIENT};SERVER”).arg(servername).arg(dbname); db.setDatabaseName(dsn);
if(db.open())
{ qDebug()<<“opened”; db.close(); }
else
{ qDebug()<<“error”<<db.lastError().text();
}
return a.exec();
}
@

Again: use @ tags around code sections please; Andre

Are you sure your dsn variable contains the correct data ? Since your not using coding tags (one @ at the beginning and one at the end) I'm not sure your are not missing a %1 and a %2 to get your servername and dbname in the string.

my dns :
@QString dsn=QString("DRIVER{Sql native client};server=%1;database=%2;trusted_connectivity=yes;").arg(servername).arg(dbname);@
