-----------------------------------------
> LOB: Add syntax to return filename of a LOB data file for external LOBs.
> -------------------------------------------------------------------------

> Key: TRAFODION-2874
> URL: https://issues.apache.org/jira/browse/TRAFODION-2874
> Project: Apache Trafodion
> Issue Type: Bug
> Components: sql-exe
> Affects Versions: 2.3
> Reporter: Sandhya Sundaresan
> Assignee: Sandhya Sundaresan
> Priority: Major
>
> For external LOBs, Trafodion does not save the LOB data in it's internal
> trafodion namespace. It saves only the LOB handle information and the actual
> LOB data remains outside in users namespace in HDFS. So inserts are very
> eifficient. During extract from an external LOB today, we extract the LOB
> data from the external file and return it to the user. Need to extend the
> Extract syntax to also be able to return the external LOB data filename alone
> .
