Postgres NOT IN (null) gives no result

notin, null, postgresql

Solution

The result of `[not] in (null)` will always be null. To compare to null you need `is [not] null` or `is [not] distinct from null`

select *
from Entity this_ 
where this_.ID is not null

If you want `where (ID not in (1,null))` as in your comment you can do

where ID is not null and ID not in (1)

Problem

I'm using Postgres with this query ``` select * from Entity this_ where (this_.ID not in (null)) ``` Why does this give me no results? I would expect to get all rows where id is not null with ``` (this_.ID not in (1)) ``` i get the expected results
