    7578=== Reports Involving Custom Fields === 
    7679 
    77 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. 
     80Custom 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`. 
    7881 
    79 The following example includes a custom ticket field named `progress` in the report: 
     82{{{ 
     83#!sql 
     84SELECT p.value AS __color__, 
     85   id AS ticket, summary, owner, c.value AS progress 
     86  FROM ticket t, enum p, ticket_custom c 
     87  WHERE status IN ('assigned') AND t.id = c.ticket AND c.name = 'progress' 
     88AND p.name = t.priority AND p.type = 'priority' 
     89  ORDER BY p.value 
     90}}} 
     91'''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. 
     92 
     93However, 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. 
    8094{{{ 
    8195#!sql 
     
    96110Note in particular the `LEFT OUTER JOIN` statement here. 
    97111 
     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}}}
