     116=== Updating the database === 
     117 
     118As 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: 
     119 
     120{{{ 
     121#!sql 
     122INSERT INTO ticket_custom 
     123   (ticket, name, value) 
     124   SELECT  
     125      id AS ticket, 
     126      'request_source' AS name, 
     127      'None' AS value 
     128   FROM ticket  
     129   WHERE id NOT IN ( 
     130      SELECT ticket FROM ticket_custom 
     131   ); 
     132}}} 
     133 
     134If 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: 
     135 
     136{{{ 
     137#!sql 
     138INSERT INTO ticket_custom 
     139   (ticket, name, value) 
     140   SELECT  
     141      id AS ticket, 
     142      'request_source' AS name, 
     143      'None' AS value 
     144   FROM ticket  
     145   WHERE id NOT IN ( 
     146      SELECT ticket FROM ticket_custom WHERE name = 'request_source' 
     147   ); 
     148}}}
