Subject Re: Cannot export TIMESTAMP column to Oracle
Date Sat, 14 Jun 2014 21:18:05 GMT
Hey there,

Are you using the standard connector or the OraOop connector? I think
OraOpp should support TIMESTAMP WITH TIME ZONE type.

NOTE: There's a review to add it as part of the standard Sqoop:
https://reviews.apache.org/r/18452/. The community is in the process of
reviewing this. Until then, it seems available here:
https://github.com/QuestSoftwareTCD/OracleSQOOPconnector.
