[jira] [Created] (SPARK-36686) fix SimplifyConditionalsInPredicate to be null-safe

Andrew created SPARK-36686:
------------------------------

             Summary: fix SimplifyConditionalsInPredicate to be null-safe
                 Key: SPARK-36686
                 URL: https://issues.apache.org/jira/browse/SPARK-36686
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.1.2
            Reporter: Andrew


SimplifyConditionalsInPredicate rule is not null-safe and leads to incorrect results

 

ex. IF(cond, trueVal, true) => OR(NOT(cond), trueVal) rewrite is invalid when cond is null. 

LHS: IF(null, trueVal, true) => true

RHS: OR(NOT(null), trueVal) => OR(NULL, trueVal)
