Oh, so if you have a column of type VARCHAR(1000) or anything longer
than 255 chars it fails too?
And I'd guess that if you have a varchar(255) column and store a value
longer than 255 bytes (because there are many wide chars) it will fail
as well.
Both cases should really be tested and taken to Zeos if they fail.
