Hi All,
I tested "concurrent testing" in MySQL. It works fine. But I couldn't do in PostgreSQL 7.3.4 on HPUX IPF. I got deadlock problem. I used the PHP script to update table( one script increment the column & another one decrement the column). Is the postgres support the concurrent access to update database?
I got the following errors:
test=# ERROR: deadlock detected
ERROR: deadlock detected
ERROR: deadlock detected

Hi there
I've noticed some very weird things happening with my current MySQL setup
on my XP Laptop, a development machine.
For a while, I have been trying to get the MySQL cache to work. Despite
entering the required lines to "my.ini" (the new my.cnf) through notepad
AND MySQL Administrator, the cache does not work.
So, today I took a peek at the 'Health' tab in MySQL Administrator.

Can someone tell me which of these 2 SQL queries will be more efficient? I'm
having a debate with another guy about which would be less resource
intensive for MySQL.
The first uses MySQL to pick a random row in a single statement:
<?php
$sql = "SELECT FROM myTable ORDER BY RAND() LIMIT 1";
$query = mysql_query($sql,$conn);
?>

I am trying to put together a PHP search page in which the user can select none, one, two, or three fields to search, and then the results php will build the SQL with dynamic where caluses to reflect the fields chosen.
The first page, where they select the search fields and submit:
<?php
$db = mysql_connect("localhost", "root", "yeahright");
if (!$db)
{
die('Could not connect:'.mysql_error);

You may be wondering why you would want to put your files “into” the database, rather than just onto the file-system. Well, most of the time, you wouldn’t.
In situations where your PHP application needs to store entire files, the preferred method is to save the file onto the server’s file-system, and store the physical location of the file in your database. This is generally considered to be the easiest and fastest way to store files.

Hello everyone! I have an app that uses a for loop to go through an array and it selects all the values from my MySQL database and returns the values. I can't imagine that this is the best approach. My code kinda looks like this:
$array = array('blah', 'bleep', 'bloop');
$password = 'same_value_for_each_item_in_the_array';
$name = 'same_value_for_each_item_in_the_array';
$userArray = array();
$passArray = array();
$nameArray =...

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...

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...
