 Note in particular the `LEFT OUTER JOIN` statement here.
 
+=== Updating the database ===
+
+As noted above, any tickets created before a custom field has been defined will not have a value for that field. Here's a bit of SQL (tested with SQLite) that you can run directly on the Trac database to set an initial value for custom ticket fields. Inserts the default value of 'None' into a custom field called 'request_source' for all tickets that have no existing value:
+
+{{{
+#!sql
+INSERT INTO ticket_custom
+   (ticket, name, value)
+   SELECT 
+      id AS ticket,
+      'request_source' AS name,
+      'None' AS value
+   FROM ticket 
+   WHERE id NOT IN (
+      SELECT ticket FROM ticket_custom
+   );
+}}}
+
+If you added multiple custom fields at different points in time, you should be more specific in the subquery on table {{{ticket}}} by adding the exact custom field name to the query:
+
+{{{
+#!sql
+INSERT INTO ticket_custom
+   (ticket, name, value)
+   SELECT 
+      id AS ticket,
+      'request_source' AS name,
+      'None' AS value
+   FROM ticket 
+   WHERE id NOT IN (
+      SELECT ticket FROM ticket_custom WHERE name = 'request_source'
+   );
+}}}
+
