     112=== Updating the database === 
     113 
     114As 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: 
     115 
     116{{{ 
     117#!sql 
     118INSERT INTO ticket_custom 
     119   (ticket, name, value) 
     120   SELECT  
     121      id AS ticket, 
     122      'request_source' AS name, 
     123      'None' AS value 
     124   FROM ticket  
     125   WHERE id NOT IN ( 
     126      SELECT ticket FROM ticket_custom 
     127   ); 
     128}}} 
     129 
     130If 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: 
     131 
     132{{{ 
     133#!sql 
     134INSERT INTO ticket_custom 
     135   (ticket, name, value) 
     136   SELECT  
     137      id AS ticket, 
     138      'request_source' AS name, 
     139      'None' AS value 
     140   FROM ticket  
     141   WHERE id NOT IN ( 
     142      SELECT ticket FROM ticket_custom WHERE name = 'request_source' 
     143   ); 
     144}}}
