I have a table called BidItem which has another table called
BidAddendum related to it by foreign key. I have another table called
BidFolder which is related to both BidItem and BidAddendum, based on a
column called RefId and one called Type, i.e. type 1 is a relationship
to BidItem and type 2 is a relationship to BidAddendum.

different types indicating which table the...

Hi,
I have an Orders Table that has Employee1 and Employee2 (one is the
sales rep the other is the telemarketing rep) Both of these fields
need to cascade update against the Employees table. I can't seem to
create the desired relationship in a Diagram and I'm not sure how best
to set this up. Any ideas?
Thanks in advance...

I want to link both UserID fields to the UserInfo table by UserID. (Since the CreatedBy will be...

Good evening all, I have a problem that I've been banging my head against for a few hours and was looking for some advice. Consider a table with the following data:
SSN (int)
first_name (char)
last_name (char)
middle_name (char)
A sampling of data would appear as such:
000112222, Jones, Jeff, J.
000112222, Jones, Jeff, Jason

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
Here is the code in...

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...
