给出以下字典理解
SELECT ur.login_id,
GROUP_CONCAT(DISTINCT ue.user_email_address) as emails,
GROUP_CONCAT(DISTINCT up.phone_number) as phones
FROM greydeltadb.gd_user ur LEFT JOIN
greydeltadb.gd_user_emails ue
ON ur.user_id = ue.user_id LEFT JOIN
greydeltadb.gd_phone up
ON ur.user_id = up.user_id
GROUP BY ur.login_id ;
我可以用某种方式对此{key: func(key) for key in range(5) if func(key) is not None}
进行注释,这样我就不必对其进行两次计算吗?预先感谢
