Обсуждение: COPY FROM FORMAT CSV FORCE_NULL(*) ?
Hi, there.
copy force null git commit didn't attach a discussion link. So I don't know if it's already been discussed.
Current seem you cannot do
COPY forcetest FROM STDIN WITH (FORMAT csv, FORCE_NULL(*));
can we have FORCE_NULL(*)? Since We already have FORCE_QUOTE(*).
I recommend David Deutsch's <<The Beginning of Infinity>>

Hi,
Agree, FORCE_NULL(*) is useful as well as FORCE_NOT_NULL(*).
We can have them both.
They are useful when users copy tables that have many columns.

We only started adding discussion links in later years. Here's a link to

Offhand I don't see why we shouldn't have this. Someone interested
enough would need to submit a patch.
