Hi Edgard,
I think your method is perfect way, maybe you can alter it a little bit like this
UNLOAD SELECT * FROM iTransRow
WHERE
EXISTS (SELECT 1 FROM iTrans AS A WHERE A.Fecha >= '2014-01-01' AND iTransRow.IdLoc=A.IdLoc AND iTransRow.IdSeq=A.IdSeq)
TO '\\transfer\itransrow.dat'
If the corrupt table contains other index, you should try using other index to salvage data
select * from iTransRow with(index ("other_index"))
Best regards
