     109=== Updating the database ===
     110
     111As 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:
     112
     113{{{
     114#!sql
     115INSERT INTO ticket_custom
     116   (ticket, name, value)
     117   SELECT
     118      id AS ticket,
     119      'request_source' AS name,
     120      'None' AS value
     121   FROM ticket
     122   WHERE id NOT IN (
     123      SELECT ticket FROM ticket_custom
     124   );
     125}}}
     126
     127If 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:
     128
     129{{{
     130#!sql
     131INSERT INTO ticket_custom
     132   (ticket, name, value)
     133   SELECT
     134      id AS ticket,
     135      'request_source' AS name,
     136      'None' AS value
     137   FROM ticket
     138   WHERE id NOT IN (
     139      SELECT ticket FROM ticket_custom WHERE name = 'request_source'
     140   );
     141}}}
