-----------------------------------
Summary: Supporting Quoted Identifiers in Column Names
Key: HIVE-6013
URL: https://issues.apache.org/jira/browse/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 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.
