Lefty Leverenz commented on HIVE-6013:
--------------------------------------
Please review the naming information in these two sections of the DDL wikidoc:
* [Create Table
|https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-CreateTable]
(right after the syntax)
* [Alter Column
|https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-AlterColumn]
Still to come: adding hive.support.quoted.identifiers to the Configuration
Properties wikidoc.

> Hive's current behavior on Quoted Identifiers is different from the normal
> interpretation. Quoted Identifier (using backticks) has a special
> interpretation for Select expressions(as Regular Expressions). Have
> documented current behavior and proposed a solution in attached doc.
> Summary of solution is:
> - Introduce 'standard' quoted identifiers for columns only.
> - At the langauage level this is turned on by a flag.
> - At the metadata level we relax the constraint on column names.
