[jira] [Created] (SPARK-28989) Add `spark.sql.ansi.enabled`

Gengliang Wang created SPARK-28989:
--------------------------------------

             Summary: Add `spark.sql.ansi.enabled`
                 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


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.
