Large text input

Any help on trying to update a column in a table that
is large ie 18k +. I tried to use the cursor and did
an execute "update table set column=@data" but it
raises an error saying something about the data is to
large for a data field even though the field in the
database is text and large enough to hold it. 

I am a newbie using this library and using sybase in
general so hopefully this is easy one to answer.
Thanks
