Lefty Leverenz commented on HIVE-1180:
--------------------------------------
For good measure, I mentioned CTEs in these sections, with links to the SELECT
syntax and CTE doc:
* [DML: Inserting data into Hive Tables from queries
|https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DML#LanguageManualDML-Notes.1]
* [DDL: CTAS
|https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-CreateTableAsSelect(CTAS)]
* [DDL: Create View
|https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-CreateView]
I also added a version note to the SELECT syntax:
* [Select Syntax

> 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.
