I've been experimenting with storing image data in blob fields, and I was
surprised that using the mysql client to select the field with a

the terminal (with lots of beeping) while using the \G query terminator

Hi,
I have had problems reading BLOB fields using MyODBC (I can't see if this is
Your way of doing this).
I have solved reading/updating BLOB using the samples from
http://www.vbmysql.com/ -
http://www.vbmysql.com/articles/visual-basic_mysql/blobaccessvb.html
Best regards
When a select query is run on a mysql table with text and blob fields, the
text fields return the whole text but the blob fields return only the first
4 bytes of the blob data. I use MySQL 4.0.17 with VB6.0 on Windows 2000.
What should I do to retrieve complete data from the blob field?
Any help
You need to select into dumpfile instead of outfile. See the section of the manual on
select syntax:

Hi,
I have the question related to this topic, hopefully you could help me on this.
Is that possible that we insert an encrypted image into blob fields where the
encryption is done by using mysql existing function (AES_Encrypt) from the client side?
If yes, how is the procedure ?
Thanks in

Lots of us know how. And we've discussed it on the list about 600 times
already. I'm sure you'll find an answer in the list archives.

tried to do. It seems that it is impossible to send large amount of binary
data to mysql's BLOB field. It is written in manual that 4.0x versions do

Well how large is the BLOB field?

Hi,
I am trying to extract blob data from a query using the C API functions
(actually I am using Delphi). I understand the structure of the result set
and need to know the length of the blob field to extract it.
As far as I can tell the only way to find the length of the fields is by
