Lefty Leverenz commented on HIVE-6687:
--------------------------------------
Added the new configuration parameter to the wiki here:
* [Configuration Properties: hive.resultset.use.unique.column.names
|https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.resultset.use.unique.column.names]
After HIVE-6037 gets committed, this parameter will have to be added to
HiveConf.java again -- see HIVE-6586:

> JDBC ResultSet fails to get value by qualified projection name
> --------------------------------------------------------------
>
> Key: HIVE-6687
> URL: https://issues.apache.org/jira/browse/HIVE-6687
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 0.12.0
> Reporter: Laljo John Pullokkaran
> Assignee: Laljo John Pullokkaran
> Labels: documentation
> Fix For: 0.13.0
>
> Attachments: HIVE-6687.4.patch
>
>
> Getting value from result set using fully qualified name would throw
> exception. Only solution today is to use position of the column as opposed to
> column label.
> {code}
> String sql = "select r1.x, r2.x from r1 join r2 on r1.y=r2.y";
> ResultSet res = stmt.executeQuery(sql);
> res.getInt("r1.x");
> {code}
> res.getInt("r1.x"); would throw exception unknown column even though sql
> specifies it.
> Fix is to fix resultsetschema in semantic analyzer.
