> Key: SPARK-30919
> URL: https://issues.apache.org/jira/browse/SPARK-30919
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.0, 3.1.0
> Reporter: Kent Yao
> Assignee: Kent Yao
> Priority: Major
> Fix For: 3.0.0
>
>
> The current behavior of interval multiply and divide follows the ANSI SQL
> standard when overflow, it is compatible with other interval operations when
> `spark.sql.ansi.enabled` is true, but not compatible when
> `spark.sql.ansi.enabled` is false.
> When `spark.sql.ansi.enabled` is false, as the factor is a double value, so
> we should use java's rounding or truncation behavior for casting double to
> integrals.
