Got a simple problem.
I code some site and because Im a freak I made my own session-handling.
When a user open up my site it will check if there is a ssid in the url
if not generate one. this will be done by a function generate_ssid() and works fine.
next step is to register the ssid in the table session
this will be done by the following code:

I want to be able to generate SQL statements that will go through a list of
data, effectively row by row, enquire on the database if this exists in the
selected table- If it exists, then the colums must be UPDATED, if not, they
must be INSERTED.
Logically then, I would like to SELECT * FROM <TABLE>
WHERE ....<Values entered here>, and then IF FOUND
UPDATE <TABLE> SET .... <Values entered here> ELSE
INSERT INTO <TABLE> VALUES <Values...

Hello,
I have created 3 functions to insert, update and delete an Access
database record. The Insert and the Delete code are working fine.
The update is not. I checked and my database has all the necessary
records in it when testing it. I get the error "No value given for one
or more required parameters." when I try to update the database.
Can you tell me what am I doing wrong?

I have an application that needs to insert nulls into the database and
I don't seem to be able to do this.
I am currently trying to do this with a Typed DataSet but I can't seem
to Insert Nulls (or udpate columns with a null value).
I have a column in a test table called 'anInteger'.
The Typed DataSet for this element has minOccurs="0" and the type =
xs:int.
To set this field to null I call the SetanIntegerNull method of my

So as you all know the great thing about ADO.NET is that I can take an
entire table from a database and dump it into an in memory datatable
using ADO.NET.
Well my question is that now that I have this temporary table, is it
possible to run SQL commands against it like it were an "actual"
table.
To give a simplistic example, lets say I have a table in my SQL Server
database called "Customers" that contains 2 columns (CustomerID,

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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,...

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...
