    44== Configuration
    5 Configuring custom ticket fields is done in the [wiki:TracIni trac.ini] file. All field definitions should be under a section named `[ticket-custom]`.

    109149=== Reports Involving Custom Fields
    … …  
    111151Custom 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`.
    112152
    113 {{{
    114 #!sql
     153{{{#!sql
    115154SELECT p.value AS __color__,
    116155   id AS ticket, summary, owner, c.value AS progress
    … …  
    123162
    124163However, 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:
    125 {{{
    126 #!sql
     164{{{#!sql
    127165SELECT p.value AS __color__,
    128166   id AS ticket, summary, component, version, milestone, severity,
    … …  
    131169   changetime AS _changetime, description AS _description,
    132170   reporter AS _reporter,
    133   (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress
     171   (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress
    134172  FROM ticket t
    135173     LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress')
    … …  
    141179Note in particular the `LEFT OUTER JOIN` statement here.
    142180
    143 Note that if your config file uses an uppercase name, e.g.,
    144 {{{
     181Note that option names in trac.ini are case-insensitive, so even if your option name includes uppercase characters:
     182{{{#!ini
    145183[ticket-custom]
    146 
    147184Progress_Type = text
    148185}}}
    149 you would use lowercase in the SQL: `AND c.name = 'progress_type'`
    150 
    151 === Updating the database
    152 
    153 As 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:
    154 
    155 {{{
    156 #!sql
    157 INSERT INTO ticket_custom
    158    (ticket, name, value)
    159    SELECT
    160       id AS ticket,
    161       'request_source' AS name,
    162       'None' AS value
    163    FROM ticket
    164    WHERE id NOT IN (
    165       SELECT ticket FROM ticket_custom
    166    );
    167 }}}
    168 
    169 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:
    170 
    171 {{{
    172 #!sql
    173 INSERT INTO ticket_custom
    174    (ticket, name, value)
    175    SELECT
    176       id AS ticket,
    177       'request_source' AS name,
    178       'None' AS value
    179    FROM ticket
    180    WHERE id NOT IN (
    181       SELECT ticket FROM ticket_custom WHERE name = 'request_source'
    182    );
    183 }}}
     186you must use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`.
