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`. 112 117 113 {{{ 114 #!sql 118 {{{#!sql 115 119 SELECT p.value AS __color__, 116 120 id AS ticket, summary, owner, c.value AS progress … … 123 127 124 128 However, 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 129 {{{#!sql 127 130 SELECT p.value AS __color__, 128 131 id AS ticket, summary, component, version, milestone, severity, … … 131 134 changetime AS _changetime, description AS _description, 132 135 reporter AS _reporter, 133 (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress136 (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress 134 137 FROM ticket t 135 138 LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress') … … 141 144 Note in particular the `LEFT OUTER JOIN` statement here. 142 145 143 Note that if your config file uses an uppercase name, e.g.,144 {{{ 146 Note that option names in trac.ini are case-insensitive, so even if your option name includes uppercase characters: 147 {{{#!ini 145 148 [ticket-custom] 146 147 149 Progress_Type = text 148 150 }}} 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 }}} 151 you must use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`. 184 152 185 153 ----
