-Trac supports adding custom, user-defined fields to the ticket module. Using custom fields, you can add typed, site-specific properties to tickets.

-=== 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 is some SQL (tested with SQLite) that you can run directly on the Trac database to set an initial value for custom ticket fields. It 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'
-   );
