Hi,

 

One case where this can happen is if the mysql client library
(libmysql.dll) is version 4 or earlier. Due to some data types that are
new to MySQL 5, a version 4 client can get the 

"Using unsupported buffer type" error when talking to a version 5
server.

 

If this is the case, then replacing libmysql.dll with a version 5 one
should fix it. For a MapGuide installation, I'm not sure of the exact
location if libmysql but someone else on the [fdo_users] group would
likely know. 

 

If you're sure you have the right version of libmysql, there's also the
chance that a libmysql from another directory is being picked up before
it, depending on the current path.

 

Brent.

Hello, 
Using MGOS 1.1, FDO 3.2, MySQL 5.0.22, Win2000... 
When setting up a MySQL connection through Studio, I keep getting the
following error:   
An exception occurred in FDO component.  RDBMS: Using unsupported buffer
type: 0  (parameter: 1) 
Below is a dump from the server log.  Does anybody have any idea as to
how to fix this? 

Error: An exception occurred in FDO component. 
        RDBMS: Using unsupported buffer type: 0  (parameter: 1)

Thanks in advance.
