<li>Delete a given spotter by ID and NULL out his/her ID in all of the associated sightings. Do this as a transaction and specify OR ROLLBACK for the UPDATE command therein. I would do the same for the DELETE command, but OR ROLLBACK is not supported for DELETE in Sqlite because foreign key constraints are not checked by Sqlite's OR ROLLBACK algorithm, and - as far as I can tell - <a href="https://www.sqlite.org/lang_conflict.html">none of the other checks performed are relevant to DELETE</a>.</li>

<p>Note that in real life, it would likely be useful to have a geospatial index on latitude and longitude. SQLite doesn't support this, but there are <a href="https://www.gaia-gis.it/fossil/libspatialite/index">add-ons</a> and <a href="https://www.linkedin.com/pulse/what-geospatial-index-gaurav-pandey">workarounds</a> (though that is not required for this assignment).</p>
