Is there any way to import long text field (longer than 128 bytes) into matlab from database?

I have a database in which some fields are string longer than 128 bytes. When I use matlab to retrieve this field only the first 128 bytes can be read. And when I export data to database, also only 128 bytes data can be imported into the database. Is there any way to import long text field into matlab from database?

I use win7 64 bits system, matlab 2013b.

Here is the code:

databasename = 'D:\data.accdb'; conn = database('','','','sun.jdbc.odbc.JdbcOdbcDriver', ... ['jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DSN='';DBQ=' databasename]); curs = exec(conn,'select distinct distribtuion from dist'); setdbprefs('DataReturnFormat',type); if isempty(curs.Message) curs = fetch(curs,0); colunames=columnnames(curs); data = curs.Data; end

I also try the matalb database importing tools, but the results is the same.

Could find nothing in the doc's on limitations. Looks like time for a query to "official" TMW support at mathworks.com
