Should'd that be
override_code = override[k].ceo_schemes_and_overrides_and_override_codes.
override_code.code1
anyway this should be faster (no nested queries)
override = db((db.ceo_schemes_and_overrides_and_override_codes.ceo_scheme ==
ceo_scheme.id) & (db.ceo_schemes_and_overrides_and_override_codes.override
== override_id)).select(left=db.override_code.on(db.
ceo_schemes_and_overrides_and_override_codes.
override_code==db.override_code.id))
override_code = override[k].override_code.code1
