Hello,
Currently we have a database, and it is our desire for it to be able
to store millions of records. The data in the table can be divided up
by client, and it stores nothing but about 7 integers.
| table |
| id | clientId | int1 | int2 | int 3 | ... |
Right now, our benchmarks indicate a drastic increase in performance
if we divide the data into different tables. For example,...

Can I set it up so that a certain combination of fields can't contain the
same entries, on another record? e.g. a combination of
FirstName/LastName/address? Or FirstName/LastName/phone? Or
FirstName/LastName/email?
Or is it possible to allow this but to throw up an alert message? Warning
that this person is probably already in the database? TIA

Anyone know, in VB.NET (2005) how to prevent duplicate occurrences of the
same event handler on an event?
e.g... I have some object which raises an event, and some other class which
consumes them. So in essence what I want to do is something like this in the
consumer class...
If Not objEventSource.SomeEvent.Handlers.Contains(AddressOf me.EventHandler)
Then _
AddHandler objEventSource.SomeEvent, AddressOf me.EventHandler

I have a unique constraint in my Oracle table for 3 fields. If I enter duplicate info on the table using Oracle client I will get an Ora message error ORA-00001 that tells me it is a duplicate entry attempt.

Hi Everyone,
I am a bit of a hobby programmer (read newbie), and I have been searching for a solution to a SQL problem for a recent pet project. I discovered that there are a number of brilliant minds hanging around here, and I was hoping someone could point me in the right direction.
I'm using MS SQL 2005 and I have created a table of "level changes" that basically stores the device name , the previous level and the new level along...

Hi,
the user gets a form to fill. All the filled values are put into session
variables.
I want to prevent that he could click to the previous arrow of the browser
and then comes back to the form. Is that possible with asp.net?
Or, is it possible to clear the session when leaving the form page by
clicking the previous arrow?

THE PROBLEM
I'm running into performance issues generating and storing a randomly created graph in a SQL Server database. I have a T-SQL script that generates a graph, and then randomly connects the vertices in that graph to each other. I can see that my hard-drive is working very hard throughout the operation. The operation took about 2 hours (I just canceled it at this point, looked like it was about 10% done) with 200,000 vertices and an...

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. 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...
