    41 === Sample Config ===
    42 {{{
     94If the `label` is not specified, it will be created by capitalizing the custom field name and replacing underscores with whitespaces.
     95
     96Macros will be expanded when rendering `textarea` fields with format `wiki`, but not when rendering `text` fields with format `wiki`.

    75 === Reports Involving Custom Fields ===
     149=== Reports Involving Custom Fields
    76150
    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.
     151Custom 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`.
    78152
    79 The following example includes a custom ticket field named `progress` in the report:
    80 {{{
    81 #!sql
     153{{{#!sql
     154SELECT p.value AS __color__,
     155   id AS ticket, summary, owner, c.value AS progress
     156  FROM ticket t, enum p, ticket_custom c
     157  WHERE status IN ('assigned') AND t.id = c.ticket AND c.name = 'progress'
     158AND p.name = t.priority AND p.type = 'priority'
     159  ORDER BY p.value
     160}}}
     161'''Note''': This will only show tickets that have progress set in them. This 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.
     162
     163However, 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:
     164{{{#!sql
    82165SELECT p.value AS __color__,
    83166   id AS ticket, summary, component, version, milestone, severity,
     
    86169   changetime AS _changetime, description AS _description,
    87170   reporter AS _reporter,
    88   (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
    89172  FROM ticket t
    90173     LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress')
     
    96179Note in particular the `LEFT OUTER JOIN` statement here.
    97180
     181Note that option names in trac.ini are case-insensitive, so even if your option name includes uppercase characters:
     182{{{#!ini
     183[ticket-custom]
     184Progress_Type = text
     185}}}
     186you must use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`.
