Apache Spark commented on SPARK-14004: -------------------------------------- User 'liancheng' has created a pull request for this issue: https://github.com/apache/spark/pull/11820 > AttributeReference and Alias should only use their first qualifier to build > SQL representations > ----------------------------------------------------------------------------------------------- > > Key: SPARK-14004 > URL: https://issues.apache.org/jira/browse/SPARK-14004 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.0.0 > Reporter: Cheng Lian > Assignee: Cheng Lian > Priority: Minor > > Current implementation joins all qualifiers, which is wrong. > However, this doesn't cause any real SQL generation bugs as there is always > at most one qualifier for any given {{AttributeReference}} or {{Alias}}. > We can probably use {{Option\[String\]}} instead of {{Seq\[String\]}} to > represent qualifiers. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
