Ashutosh Chauhan commented on HIVE-6013:
----------------------------------------
Approach looks ok to me. Some implementation level comments on RB.
One test scenario. If this is already covered in your test, feel free to
ignore. Otherwise, can you add following test.
set hive.support.quoted.identifiers=column;
create table t1 (aa int, ab string);
select a.* from t1; -- this should select both columns.
Also, you mentioned in html doc, some of jdbc api methods need to change, but I
don't see any changes in jdbc package.
> 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'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.
