> Fix AlwaysTrue/AlwaysFalse predicate translation in JDBC connectors
> -------------------------------------------------------------------

> Key: SPARK-53454
> URL: https://issues.apache.org/jira/browse/SPARK-53454
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 4.1.0

> If AQE changes the plan so that the predicate is AlwaysTrue or AlwaysFalse,
> generated JDBC SQL query would be 'WHERE 1' or 'WHERE 0'. Some dialects don't
> support it, so we should change the SQL generation to something any dialect
> can handle.
> Therefore, I propose translating it to 'WHERE 1=1' or 'WHERE 1=0'
