Subject [Db-derby Wiki] Update of "TriggerImplementation" by DanDebrunner
Date Thu, 27 Apr 2006 03:02:52 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Db-derby Wiki" for change notification.

The following page has been changed by DanDebrunner:

  === Possible Changes ===
   * Re-write triggers to not add the indirection through JDBC !ResultSet. Have old/new references
in action statements compile to specific !QueryTree nodes that access the data directly from
a Derby language !ResultSet. Would need to investigate how to handle existing triggers at
upgrade time.
   * Continue with JDBC approach and add code as required to fix issues, e.g. a internal specific
!findColumn implementation that doesn't match JDBC but instead matches column on absolute
name. Might still require a wrapper JDBC object.
+  * Use column position rather than column name to fetch a column value for a row trigger.
