Possible to add datatypes to database toolbox

Hi! I'm running into the "Unsupported data type" error trying to fastinsert a Matlab string into a uniqueidentifier-typed field in an SQL Server 2008 database. Is there some way to get the database toolbox to recognize datatypes it doesn't already know about? Thanks!

Which MATLAB version are you running and can you make a very small example to reproduce your problem?

I've had an issue trying to insert a NULL (or empty) into a non-standard table column... but it looks like your error is coming from line 246 of fastinsert.m... am I right?
