Summary: Strip auto-generated cast when resolving UnresolvedAlias
Key: SPARK-33989
URL: https://issues.apache.org/jira/browse/SPARK-33989
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.2.0
Reporter: ulysses you
During analysis we may introduce the Cast if exists type cast implicitly. That
makes assgined name unclear.
Let's say we have a sql `select id == null` which id is int type, then the
output field name will be `(id = CAST(null as int))`.
