[jira] [Commented] (DERBY-6445) JDBC 4.2: Add support for new date and time classes

JIRA jira@apache.org

    [ https://issues.apache.org/jira/browse/DERBY-6445?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15848534#comment-15848534 ]

Knut Anders Hatlen commented on DERBY-6445:
-------------------------------------------

I cannot recall what I said about setNull(), and I don't think anything is needed there. As to getObject(), even if this conversion is only mentioned in the conversion tables for setObject(), [the spec for getObject()|http://docs.oracle.com/javase/8/docs/api/java/sql/ResultSet.html#getObject-int-java.lang.Class-] says:

"At a minimum, an implementation must support the conversions defined in Appendix B, Table B-3 and conversion of appropriate user defined SQL types to a Java type which implements SQLData, or Struct. Additional conversions may be supported and are vendor defined."

So it sounds like we're free to add more conversions, and I think these ones make sense.

> JDBC 4.2 added type mappings for new date and time classes found in Java 8. Derby should support these new mappings.
> This would at least affect Derby's implementation of the various getObject(), setObject() and setNull() methods in ResultSet, PreparedStatement and CallableStatement.
