Cheng Lian created SPARK-14004: ---------------------------------- Summary: 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
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
