    102 '''Note''': 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 is all that is required, you're set.

    104127However, 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:
    … …  
    128151you would use '''lowercase''' in the SQL: `AND c.name = 'progress_type'`.

    130 === Updating the database
    131 
    132 As noted above, any tickets created before a custom field has been defined will not have a value for that field. Here is some SQL (tested with SQLite) that you can run directly on the Trac database to set an initial value for custom ticket fields. It inserts the default value of 'None' into a custom field called 'request_source' for all tickets that have no existing value:
    133 
    134 {{{#!sql
    135 INSERT INTO ticket_custom
    136    (ticket, name, value)
    137    SELECT
    138       id AS ticket,
    139       'request_source' AS name,
    140       'None' AS value
    141    FROM ticket
    142    WHERE id NOT IN (
    143       SELECT ticket FROM ticket_custom
    144    );
    145 }}}
    146 
    147 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:
    148 
    149 {{{#!sql
    150 INSERT INTO ticket_custom
    151    (ticket, name, value)
    152    SELECT
    153       id AS ticket,
    154       'request_source' AS name,
    155       'None' AS value
    156    FROM ticket
    157    WHERE id NOT IN (
    158       SELECT ticket FROM ticket_custom WHERE name = 'request_source'
    159    );
    160 }}}
