[Prabu Subroto <prabu_subroto@xxxxxxxxx>]

Dear my friends...

I am using Qt3.2, Postgres and SuSE 9.1 .

I want to use "commit()" and "rollback()" mechanism
for my database application.
I defined my connection as underbelow:

    bd = QSqlDatabase::addDatabase("QPSQL7", "OTHER");
    bd->setHostName("192.168.23.237");
    bd->setDatabaseName("kv");
    bd->setUserName("postgres");
    bd->setPassword("");
    bd->transaction();
    if ( ! bd->open() )
    {
	bd->lastError().showMessage();
    }

But if I execute my application, I find this error
message in my linux console:

patrixlinux@patrix:~/arsip/proyek/qt/kv/client>
QPSQLDriver::beginTransaction: Database not open

And I also can do any SQL Query.

Where is my fault?

Please tell me.

Thank you very much in advance.
