> Key: SPARK-26653
> URL: https://issues.apache.org/jira/browse/SPARK-26653
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: Maxim Gekk
> Priority: Minor
>
> JDBCRelation should use java.time classes to convert textual representation of TimestampType and DateType to bound values. In particular, the method should be re-implemented:
> https://github.com/apache/spark/blob/115fecfd840d58ce3211bf1dd7b130cb862730a5/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/jdbc/JDBCRelation.scala#L177-L181
> Ideally the method should be able to support at least the same patterns as Cast expression.
