I go through a series of SELECT INTO in a trigger function.
SELECT INTO country_id id
FROM vcountry WHERE [...];
I might or o might not find a result.
Next, I try to find a region within this country, if found previously,
and if not anywhere.
SELECT INTO
country_id, region_id
country_fk, id
FROM vregion
WHERE (country_id IS NULL OR country_fk = country_id) AND name ILIKE
place;
If the first search found a country, and the second search fails to
find the region, the second search will set my variables to NULL. So, a
previously populated country_id will now be NULL.
Is there any way I can avoid this or do I have to use different sets of
variables?
