{{{
from django.db import connection

q = Subquery(App.objects.all())

print(str(q.query))

# Output SQL is valid:
#  'SELECT ""apps_app"".""id"", ""apps_app"".""name"" FROM ""apps_app""'

print(q.as_sql(q.query.get_compiler('default'), connection))

# Outptut SQL is invalid (no S letter at the beggining and "" symbol at the end):
# ('(ELECT ""apps_app"".""id"", ""apps_app"".""name"" FROM ""apps_app)', ())
