Dear SQLiters,

If an INSERT ... ON CONFLICT DO UPDATE statement detects that a row
already exists and needs to be updated, it doesn't seem to set lastRowid

       on conflict (firstname, lastname) do update set phonenumber = 
excluded.phonenumber;
   > select last_insert_rowid();
   2

I'd like to have obtained 1 instead, the rowid for John Doe.

I imagine the reasoning behind this is that if there was no inserted row,
then last_*insert*_rowid should remain as it was... but is there any way
to obtain this information, other than making a subsequent SELECT?

Replying to myself: I ended up doing exactly this – a subsequent SELECT after 
the
upsert; while this approach is working, it does feel suboptimal.
