[jira] Commented: (DERBY-1585) derbylang/procedureInTrigger: not able to create trigger due to an open ResultSet

    [ https://issues.apache.org/jira/browse/DERBY-1585?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12548330 ] 

Daniel John Debrunner commented on DERBY-1585:
----------------------------------------------

Section 4.27.5 of the TECHNICAL CORRIGENDUM 1 to the SQL 2003 Standard details what happens to dynamic result sets in detail, the SQL 2003 foundation document is missing these details. 

If the dynamic result sets are unreachable, which they will be for a CALL statement as a trigger's single action statement, then they must be destroyed, which is ResultSet.close() in JDBC terms.

Thus I think the general idea of the close.diff is correct, but I think a cleaner implementation would be to encapsulate the logic in the close of the activation for the CALL statement. (also need to ensure that all result sets are closed, regardless of any exceptions).
