Mr. Kyte's article doesn't use cursors, while Mr. Feuerstein's
book examples do. my recollection of conventional wisdom is
to avoid using cursors.
is this difference merely a question of style, or is one
approach right and the other wrong?

Hello All!
We have a cursor in an application which fetches some data out of a DB2-DB.
Normally it all works kind of well.
We inserted a routine at certain places in order to do some
perfomance-monitoring .
Now we got the problem, that the cursor closes at some point although not
all the data has been fetched and then next fetch of the application causes
an error.
Is there a way to force the cursor to stay open?

What are the different effects of the following two statements:
C1.Cursor = Cursors.WaitCursor
C1.Cursor.Current = Cursors.WaitCursor
I believe the first replaces the entire C1.Cursor object with a new one
while the second only replaces the Current object of C1.Cursor, but I can't

Hello all,
I asked this question a slightly different way earlier and didnt get a
response so I thought I would rephrase it. I contacted db2 support on
it also but never got a definite answer..I got a lot of "should be"
and "maybe".

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
