Lefty Leverenz commented on HIVE-1180:
--------------------------------------
Apologies for the delay, [~rhbutani]. I made these changes (please revert
anything you disagree with):
* [changes to Common Table Expression
|https://cwiki.apache.org/confluence/pages/diffpages.action?pageId=38572242&originalId=40504878]
* [current CTE doc
|https://cwiki.apache.org/confluence/display/Hive/Common+Table+Expression]
I also recommend changing COMMA to "," in the syntax -- just because I recently
got confused by DOT for "." in the DDL wiki -- but since the examples show
actual commas there shouldn't be any confusion here.

> I've seen some presentations from the PostgreSQL recently expounding the
> utility of CTEs (http://en.wikipedia.org/wiki/Common_table_expressions).
> Should we try to support these in Hive? I've never used them in practice, so
> curious to hear if the community would find them useful.
