------------------------------------
Summary: Support trailing commas in select list
Key: SPARK-47427
URL: https://issues.apache.org/jira/browse/SPARK-47427
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 4.0.0
Reporter: Serge Rielau
DuckDb has popularized allowing trailing commas in the SELECT list.
The benefit of this ability is that it is easy to add, remove, comment out
expressions from the select list:
{noformat}
SELECT c1,
/* c2 */
FROM T;
vs
SELECT c1
/* , c2 */
FROM T;
{noformat}
Recently Snowflake jumped onto this usability feature as well.
