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.
