Gengliang Wang reassigned SPARK-35030:
--------------------------------------
Assignee: Apache Spark
> ANSI SQL compliance
> -------------------
>
> Key: SPARK-35030
> URL: https://issues.apache.org/jira/browse/SPARK-35030
> Project: Spark
> Issue Type: Epic
> Components: SQL
> Affects Versions: 3.0.0, 3.1.1, 3.2.0
> Reporter: Gengliang Wang
> Assignee: Apache Spark
> Priority: Major
>
> Build an ANSI compliant dialect in Spark, for better data quality and easier
> migration from traditional DBMS to Spark. For example, Spark will throw an
> exception at runtime instead of returning null results when the inputs to a
> SQL operator/function are invalid.
> The new dialect is controlled by SQL Configuration `spark.sql.ansi.enabled`:
> {code:java}
> -- `spark.sql.ansi.enabled=true`
> SELECT 2147483647 + 1;
> java.lang.ArithmeticException: integer overflow
> -- `spark.sql.ansi.enabled=false`
> SELECT 2147483647 + 1;
> +----------------+
> |(2147483647 + 1)|
> +----------------+
> | -2147483648|
> +----------------+
> {code}
> Full details of this dialect are documented in
> [https://spark.apache.org/docs/latest/sql-ref-ansi-compliance.html|https://spark.apache.org/docs/latest/sql-ref-ansi-compliance.html].
> Note that some ANSI dialect features maybe not from the ANSI SQL standard
> directly, but their behaviors align with ANSI SQL's style.
