Hyukjin Kwon commented on SPARK-40624:
--------------------------------------
Does it work if you set {{spark.sql.ansi.enabled}} on?
> A DECIMAL value with division by 0 errors in DataFrame but evaluates to NULL
> in SparkSQL

> Key: SPARK-40624
> URL: https://issues.apache.org/jira/browse/SPARK-40624
> Project: Spark
> Issue Type: Bug
> Components: Spark Shell
> Affects Versions: 3.2.1
> Reporter: xsys
> Priority: Major
>
> h3. Describe the bug
> Storing an invalid value (e.g. {{{}BigDecimal("1.0/0"){}}}) via
> {{spark-shell}} errors out during RDD creation. However, {{1.0/0}} evaluates
> to {{NULL}} if the value is inserted into a {{DECIMAL(20,10)}} column of a
> table via {{{}spark-sql{}}}.
> h3. To Reproduce
> On Spark 3.2.1 (commit {{{}4f25b3f712{}}}), using {{{}spark-sql{}}}:
> {code:java}
> $SPARK_HOME/bin/spark-sql{code}
> Execute the following: (evaluated to {{{}NULL{}}})
> {code:java}
> spark-sql> create table decimal_vals(c1 DECIMAL(20,10)) stored as ORC;
> spark-sql> insert into decimal_vals select 1.0/0;
> spark-sql> select * from decimal_vals;
> NULL{code}
> Using {{{}spark-shell{}}}:
> {code:java}
> $SPARK_HOME/bin/spark-shell{code}
> Execute the following: (errors out during RDD creation)
> {code:java}
> scala> val rdd = sc.parallelize(Seq(Row(BigDecimal("1.0/0"))))
> java.lang.NumberFormatException
> at java.math.BigDecimal.<init>(BigDecimal.java:497)
> at java.math.BigDecimal.<init>(BigDecimal.java:383)
> at java.math.BigDecimal.<init>(BigDecimal.java:809)
> at scala.math.BigDecimal$.exact(BigDecimal.scala:126)
> at scala.math.BigDecimal$.apply(BigDecimal.scala:284)
> ... 49 elided{code}
> h3. Expected behavior
> We expect the two Spark interfaces ({{{}spark-sql{}}} & {{{}spark-shell{}}})
> to behave consistently for the same data type & input combination
> ({{{}BigDecimal{}}}/{{{}DECIMAL(20,10){}}} and {{{}1.0/0{}}}).
