Summary: Constant propagation nullability issue
Key: SPARK-30447
URL: https://issues.apache.org/jira/browse/SPARK-30447
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.0.0
Reporter: Peter Toth
There is a bug in constant propagation due to null handling:
SELECT * FROM t WHERE NOT(c = 1 AND c + 1 = 1) returns those rows where c is
null due to 1 + 1 = 1 propagation, but it shouldn't.
