When running myblob_command, i get the following error.

Error using COM.ADODB_Recordset/Open
Invoke Error, Dispatch Exception:
Source: ADODB.Recordset
Description: The connection cannot be used to perform this operation. It is either
closed or invalid in this context.
Help File: C:\WINDOWS\HELP\ADO270.CHM
Help Context ID: 12ee52

I have not figured out a way to fix this

PLEASE HELP!

Hi,
what is command_text should be in myblob_to_db (ado_connection, table, column, where, file) function ?

Nice. I was wondering if anybody has tried to write to a BLOB not from a file but directly from a Matlab matrix variable? Say, a 5x5 double matrix? Skip writing to a .mat and reading back out of the file to save time?

Additionally, to allow this to work from 64-bit Matlab, install the 64-bit version of MSDASQL via a Microsoft hot fix (link below) and add "provider=MSDASQL" to the connection string

@Lucy: Matlab 2008b seems to work with the MySQL ODBC 3.51 Driver and the MySQL ODBC 5.1 Driver. If you want to use the MySQL ODBC 5.1 Driver you have to change line 22 in myblob_open.m from
'driver=MySQL ODBC 3.51 Driver; ' ...
to
'driver=MySQL ODBC 5.1 Driver; ' ...

using Matlab 2008a and MySql 5.0 for Win32:

??? Invoke Error, Dispatch Exception:
Source: Microsoft OLE DB Provider for ODBC Drivers
Description: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

Error in ==> myblob_open at 40
ado_connection.Open;

Error in ==> myblob_demo at 26
connection = myblob_open (user, password, server, database);

Beware, this only seems to work on windows.

Works well, even if you don't need blob capability.
