Harish Butani created HIVE-6013: ----------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
