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 working application inserting rows to a table using the array
interface. Now I want to insert BLOBs as well but OCIStmtExecute crashes
when executed with BLOBs.
For BLOB types I use OCIDescriptorAlloc() and uses this to allocate
space for my data (app. 1Mb). Afterwards I store data in memory
allocated by OCIDescripterAlloc.

Hi,
Is it at all possible to insert BLOBs using the Array Interface?
Today I have an application using the array interface. It works fine but
so far I haven't been using BLOBs. I insert 100-200 rows in one server
round trip.
Now I want to have one or more colums of type BLOB but I cant see how
this can fit into my current application.

Hi -
I have an application which is essentially 'read-only' -
once the database is loaded it is only read from. So,
I am trying to implement it with various indices and
a table containg some large content in blob columns.
I observe the max_allowed_packet setting and
'split' blobs too large among multiple rows. All is fine
during testing. However, when I try a production
load (which should load about 1.5G to the various

My situation is that I am interacting PHP 4.1.2 to PostgreSQL 7.2.2
I have no difficulty inserting and managing BLOBs into the Large Object
system table, and I have a user table called images which maintains the
relationship between the BLOB loid and the identity that relates to it in
my user tables. So far so good.
When I RTFM obout psql it refers to the \lo_import, \lo_list, \lo_export
and \lo_unlink functions.

Hi,
I am still not sure whether the BLOBS are actually
stored in the database or they have the pointer to the
database for that file in the filesystem. If I remove
the files (sources) for BLOBS from the directories
with the BLOB still hold the data ?
Also one more very intriguing part is that if BLOBS
are not deleted if we delete them from tables how to

Hi there,
I am using the DB2 universal JDBC driver type 4 to insert BLOBs into a
DB2 database. The Method I used for supplying the BLOB data value is
setBinaryStream(). Everything works fine as long as the binary data is
less than or equal to 100k. Anything larger than that (even for one
byte) will result an exception saying the value is too large.
All the DB2 samples (at least two)I have found have a limit of 100k
(magic number!!!),...

Hello Members,
I am setting up a photo website. I have decided to use PHP and MySQL.
I can load jpeg files into the table (medium blob, or even longtext)
and get the image(s) to display without a problem. I am using
chunk_split(data) and the base64_encode and base64_decode on the files.
I do a select from the database, and then echo the image (with
header(Content Type: image/jpeg)
and the decoded image displays fine. Yes, I have...

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:

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,...

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...
