What SQL query should I perform to get the result set expected, giving the first element of the chain (2) as input data, or any of them ? <pre><code>table name: changes +----+---------------+---------------+ | id | new_record_id | old_record_id | +----+---------------+---------------+ | 1| 4| 2| | -- non relevant data -- | | 6| 7| 4| | -- non relevant data -- | | 11| 13| 7| | 12| 14| 13| | -- non relevant data -- | | 31| 20| 14| +----+---------------+---------------+ Result set expected: +--+ | 2| | 4| | 7| |13| |14| |20| +--+ </code></pre> I know I should consider change my data model, but: What if I couldn't? Thank you in advance!

2. COI'm going on the assumption there aren't a fixed number of records that could be returned, so a list of joins is out of the question (to traverse the tree). However, what signals the end of the list? (is it when the `new_record_id` doesn't have a mating `old_record_id`?)

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
