Date Thu, 12 Dec 2013 00:06:07 GMT
Harish Butani created HIVE-6013:

             Summary: Supporting Quoted Identifiers in Column Names
                 Key: HIVE-6013
             Project: Hive
          Issue Type: Improvement
          Components: Query Processor
            Reporter: Harish Butani
         Attachments: QuotedIdentifier.html

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

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.
