    7482=== Reports Involving Custom Fields ===
    7583
    76 The SQL required for TracReports to include custom ticket fields is relatively hard to get right. You need a `JOIN` with the `ticket_custom` field for every custom field that should be involved.
     84Custom ticket fields are stored in the `ticket_custom` table, not in the `ticket` table. So to display the values from custom fields in a report, you will need a join on the 2 tables. Let's use an example with a custom ticket field called `progress`.
    7785
    78 The following example includes a custom ticket field named `progress` in the report:
     86{{{
     87#!sql
     88SELECT p.value AS __color__,
     89   id AS ticket, summary, owner, c.value AS progress
     90  FROM ticket t, enum p, ticket_custom c
     91  WHERE status IN ('assigned') AND t.id = c.ticket AND c.name = 'progress'
     92AND p.name = t.priority AND p.type = 'priority'
     93  ORDER BY p.value
     94}}}
     95'''Note''' that this will only show tickets that have progress set in them, which is '''not the same as showing all tickets'''. If you created this custom ticket field ''after'' you have already created some tickets, they will not have that field defined, and thus they will never show up on this ticket query. If you go back and modify those tickets, the field will be defined, and they will appear in the query. If that's all you want, you're set.
     96
     97However, if you want to show all ticket entries (with progress defined and without), you need to use a `JOIN` for every custom field that is in the query.
    7998{{{
    8099#!sql
     
    95114Note in particular the `LEFT OUTER JOIN` statement here.

     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}}}
