----------------------------------
Summary: Support expressing unresolved attributes using
$"attribute name" notation in SQL DSL
Key: SPARK-5040
URL: https://issues.apache.org/jira/browse/SPARK-5040
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Reynold Xin
Assignee: Reynold Xin
The SQL DSL uses Scala symbols to represent attributes, e.g. 'attr. Symbols,
however, cannot capture attributes with spaces or uncommon characters. Here we
suggest supporting $"attribute name" as an alternative.
