Yeah, every time I see something cool done with triggers, I remember that I need to start using triggers.

This could use a new plugin hook, too. I don't want to complicate your life too much, but for things like GIS, I'd want a way to turn regular JSON into SpatiaLite geometries or combine X/Y coordinates into point geometries and such. Happy to help however I can.

@eyeseast Maybe you could do this with triggers? Like you can insert JSON-friendly data into a "raw" table, and create a trigger that transforms that inserted data into the proper table

Here's an example:

```sql -- meant to be updated from a Datasette insert create table points_raw(longitude int, latitude int);

-- the target table with proper spatliate geometries create table points(point geometry);

CREATE TRIGGER insert_points_raw INSERT ON points_raw BEGIN insert into points(point) values (makepoint(new.longitude, new.latitude)) END; ```

You could then POST a new row to points_raw like this: POST /db/points_raw Authorization: Bearer xxx Content-Type: application/json { "row": { "longitude": 27.64356, "latitude": -47.29384 } }

Then SQLite with run the trigger and insert a new row in points with the correct geometry point. Downside is you'd have duplicated data with points_raw, but maybe it could be a TEMP table (or have a cron that deletes all rows from that table every so often?)
