Apache Spark reassigned SPARK-8654: ----------------------------------- Assignee: Apache Spark > Analysis exception when using "NULL IN (...)": invalid cast > ----------------------------------------------------------- > > Key: SPARK-8654 > URL: https://issues.apache.org/jira/browse/SPARK-8654 > Project: Spark > Issue Type: Bug > Components: SQL > Reporter: Santiago M. Mola > Assignee: Apache Spark > Priority: Minor > > The following query throws an analysis exception: > {code} > SELECT * FROM t WHERE NULL NOT IN (1, 2, 3); > {code} > The exception is: > {code} > org.apache.spark.sql.AnalysisException: invalid cast from int to null; > at > org.apache.spark.sql.catalyst.analysis.CheckAnalysis$class.failAnalysis(CheckAnalysis.scala:38) > at > org.apache.spark.sql.catalyst.analysis.Analyzer.failAnalysis(Analyzer.scala:42) > at > org.apache.spark.sql.catalyst.analysis.CheckAnalysis$$anonfun$checkAnalysis$1$$anonfun$apply$2.applyOrElse(CheckAnalysis.scala:66) > at > org.apache.spark.sql.catalyst.analysis.CheckAnalysis$$anonfun$checkAnalysis$1$$anonfun$apply$2.applyOrElse(CheckAnalysis.scala:52) > {code} > Here is a test that can be added to AnalysisSuite to check the issue: > {code} > test("SPARK-XXXX regression test") { > val plan = Project(Alias(In(Literal(null), Seq(Literal(1), Literal(2))), > "a")() :: Nil, > LocalRelation() > ) > caseInsensitiveAnalyze(plan) > } > {code} > Note that this kind of query is a corner case, but it is still valid SQL. An > expression such as "NULL IN (...)" or "NULL NOT IN (...)" always gives NULL > as a result, even if the list contains NULL. So it is safe to translate these > expressions to Literal(null) during analysis. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
