Description

Problem Description

I'm reducing some Q objects (similar to what is described in ticket:32554. Everything is fine for the case where the result is ExpressionWrapper(Q(pk__in=[])). However, when I reduce to ExpressionWrapper(~Q(pk__in=[])) the query breaks.

Symptoms

Working for ExpressionWrapper(Q(pk__in=[]))

print(queryset.annotate(foo=ExpressionWrapper(Q(pk__in=[]), output_field=BooleanField())).values("foo").query)

SELECT 0 AS "foo" FROM "agri_data_declaration"

Not working for ExpressionWrapper(~Q(pk__in=[]))

print(declarations.annotate(foo=ExpressionWrapper(~Q(pk__in=[]), output_field=BooleanField())).values("foo").query)

SELECT  AS "foo" FROM "agri_data_declaration"
