     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}}}
