-----------------------------------
Summary: Introduce ANSI SQL Dialect (was: Add `spark.sql.ansi.enabled`)
> Introduce ANSI SQL Dialect
> --------------------------
>
> Key: SPARK-28989
> URL: https://issues.apache.org/jira/browse/SPARK-28989
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Gengliang Wang
> Assignee: Gengliang Wang
> Priority: Major
> Fix For: 3.0.0
>
>
> Currently, there are new configurations for compatibility with ANSI SQL:
> * spark.sql.parser.ansi.enabled
> * spark.sql.decimalOperations.nullOnOverflow
> * spark.sql.failOnIntegralTypeOverflow
> To make it simple and straightforward, let's merge these configurations into
> a single one, `spark.sql.ansi.enabled`. When the configuration is true, Spark
> tries to conform to ANSI SQL specification. It will be disabled by default.
