-----------------------------------
Summary: Support column list as the pivot column in Pivot
Key: SPARK-24164
URL: https://issues.apache.org/jira/browse/SPARK-24164
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.3.0
Reporter: Maryann Xue
This is part of a functionality extension to Pivot SQL support as SPARK-24035.
Currently, we only support a single column as the pivot column, while a column
list as the pivot column would look like:
{code:java}
SELECT * FROM (
SELECT year, course, earnings FROM courseSales
)
PIVOT (
sum(earnings)
FOR (course, year) IN (('dotNET', 2012), ('Java', 2013))
);{code}
