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've been testing the Cookbook example 8.6 (2002 edition) re using cPickle to
insert and retrieve BLOBs from mySQL, using Python's MySQLdb module.
When I try to cPickle.loads(blob), I get an error telling me that loads wants a
string, not type array.array. So I go cPickle.loads(blob.tostring()) instead
and it works.
My question is: has something changed in the Python API since this example was
written?

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);

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...

So I need to load lots of data into my database.
So I discover LOAD DATA INFILE.
Great! This little gem loads my CSV in blazing times (compared to
parsing the file and doing INSERT for each row). Its still slow on
large files, but just barely acceptable.
Only one problem. It truncates fields to 256 characters, even on a
text field.

Hi all,
I've run into a strange error while trying to store some PNG images in
a MySQL database using MySQLdb. When I try to insert smaller images (<
64kb or so) everything seems to work fine. When I start trying to
insert larger images (~150kb), however, the images get corrupted along
the way.
The result is that only part of the image, e.g. the top 30% of the
image, is stored in the database, and the rest is simply transparent.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
