Help! This is driving me crazy...
I'm trying to read a BLOB from a db and display it in a browser, like
so:
$query="SELECT blob from table where blob_id=9";
$result=mysql_query($query);
$blob=mysql_fetch_assoc($result);
Now when I do
print_r (array_values($blob));

I have to add a date column to a db2/zos table with a blob column.
Can I rename the blob table to old,
create a new table with the date column,
then insert/select the data from the old table?
Do I have to select data from the main table and the aux table or is the aux
table done automatically?
What's the best way to handle this?

I would like to be able to extract a BLOB from the database (SqlServer)
and pass it to a browser without writing it to a file. (The BLOB's
are word doc's, MS project doc's, and Excel spreadsheets.
How can I do this?

Hi,
I need a quick solution to make my application behave correctly when one
of these timeouts occurs. I have some logic in session_start but when
the authentication cookie timeouts the user is redirected to login page
and after successful login the session is not started. I'd like to have
one timeout and when it occurs the user must login and then the new
session is started. TIA.
Regards,
mircu

hello,
im doing my first ASP.NET app that inserts & retrieves files from
Oracle (no need for a discussion on *that*!).
i learned first-hand of the somewhat awkward technique for inserting
binary data into an Oracle BLOB column via ADO.NET. since my files are
larger than 33k, it seemed had to use this technique:

I have a TcpClient. I set the read/write timeouts at 1 minute (in
milliseconds). I get a NetworkStream from it and confirm the timeouts
still exist. I do a NetworkStream.Write() and then a

or the Read() -- for 15 minutes before I get fed up and close the
app.....

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

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...
