I have over 5000 thumbnail pictures of size 5kb each. I would like to
able to load all 5000 pictures and view 50 per page using
mysql_data_seek(). I would like to know what are the advantages and
disadvantages of using a MySQL blob field rather than reading the
images directly from the file? How does one insert an image into a
blob field? Can it be done dynamically?
Thank you
John

Is there any PHP function that will allow me to determine the MIME type
of a blob stored in MySQL?
Specifically, if I'm storing an image as a blob in MySQL, is there any
PHP function that can determine whether it's a gif, jpeg, png, etc?

I cannot seem to store binary data as a BLOB.
I used the following to create a table capable of holding a BLOB:
CREATE TABLE blob_table
(
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
binary_stuff BLOB,
PRIMARY KEY (id)
);

Hi,
I have a blob field in a mysql database table. I want to copy a blob
from one record to another. I am having trouble transferring the data
via a php variable. Maybe I need to addslashes or convert to Hex or
something. I've tried a few things but can't quite get it. Here is
simplified code.
mysql_select_db($dbname, $connection);

I'm implementig a java web application using MySQL as database.
The main function of the application is basically to redistribuite
documents. Those documents (PDF, DOC with an average size around 2Mb)
are stored in BLOB column.
The amount of documents for the first year should not exceed 5/6 Giga,
but I cannot make prevision for the next years.
Those documents are mainly just accessed (update and delete are not so

Dear Group,
I'm connecting in C# with remote (BSD) MySQL server with ODBC Driver,
and I'm trying to find the best sollution in such problem:
As I've read on MySQL manual, they have suggested table design
including the BLOB-Fieldtype size in UInt64, where they've stored,
while inserting, the size of inserted BLOB data. But in the matter of
fact, I'm interested if it's necessary to include in table this integer
field? Is there any way...

Is it possible to take the contents of a MySQL DB Table, and somehow

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,...
