The problem is something to do with the fact the the LONG type is only max.
32K in length, while the LONG type in database storage is nearly 2G.

What SQL are you executing my best guess is to not include the field in the update
if the memo is empty. Or you may want to try to change the table type from LONG to varchar(4000) or BLOB depending
on what you are putting in it.

What I do is use varchar(4000)'s for memeo fields and create the sql like:
If that doesn't help give me the table structure and if the memo fields are empty or not?
