Apache Spark reassigned SPARK-38407: ------------------------------------ Assignee: Gengliang Wang (was: Apache Spark) > ANSI Cast: loosen the limitation of casting non-null complex types > ------------------------------------------------------------------ > > Key: SPARK-38407 > URL: https://issues.apache.org/jira/browse/SPARK-38407 > Project: Spark > Issue Type: Sub-task > Components: SQL > Affects Versions: 3.3.0, 3.2.2 > Reporter: Gengliang Wang > Assignee: Gengliang Wang > Priority: Major > > When ANSI mode is off, `ArrayType(DoubleType, containsNull = false)` can't > cast as `ArrayType(IntegerType, containsNull = false)` since there can be > overflow thus result in null results and breaks the non-null constraint. > > When ANSI mode is on, currently Spark SQL has the same behavior. However, > this is not correct since the non-null constraint won't be break. Spark SQL > can just execute the cast and throw runtime error on overflow, just like > casting DoubleType as IntegerType. > > This applies to MapType and StructType as well. > -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
