I suppose the problem related to auto replacement of dots on underscores which was fixed in TEIID-4913 issue. Maybe it's worth to introduce some kind of indexes in column names if there is already a column with the same name instead of throwing out DuplicateRecordException. Or maybe there is an another solution.
