It seems that you have bad data in char/varchar fields somewhere in
your records.

Try to do a select fetching all rows from the problematic table. If
the error happens during the select, check what was the lastest
recorded retrieved. Probably the record with error is the next one.
Or try blocking the fetch (using first/skip) until you find what is
the problematic record(s).
