Myblob

Exchange blobs (binary large objects) with MySQL databases

Description

MYBLOB_DEMO - Demonstrate the use of the MYBLOB tool kit
MYBLOB_OPEN - Open the connection to a MySQL database
MYBLOB_COMMAND - Send an SQL statement to a MySQL database
MYBLOB_FROM_DB - Retrieve a blob (binary large object) from a MySQL database
MYBLOB_TO_DB - Send a blob (binary large object) to a MySQL database
MYBLOB_CLOSE - Close the connection to the MySQL database

* Install MyODBC from www.mysql.com
* Insert your own MySQL database parameters in myblob_demo.m
* Run myblob_demo

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

nice, just what I was looking for.

Beware, this only seems to work on windows.

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);

@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; ' ...

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
