Harish Butani commented on HIVE-6013: ------------------------------------- No with hive.support.quoted.identifiers=column names in backticks are treated literally. Select * is supported in either case. Had a cursory look at the examples, don't see why they need to be changed. Are there particular ones you are referring to. > 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 > Assignee: Harish Butani > Fix For: 0.13.0 > > Attachments: HIVE-6013.1.patch, HIVE-6013.2.patch, HIVE-6013.3.patch, > HIVE-6013.4.patch, HIVE-6013.5.patch, HIVE-6013.6.patch, HIVE-6013.7.patch, > 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 (v6.1.5#6160)
