一个复杂的sql语句

# 查询总数，打标数量，未打标数量
SELECT plan.id as id,  domain, tag.recover , COUNT(domain) as num,
COUNT(CASE WHEN tag.recover  = '已关联' or tag.recover  = '无法关联' THEN 
                      1 ELSE NULL END) as taged,
COUNT(CASE WHEN tag.recover  is NULL THEN 
                      1 ELSE null END) as untaged
FROM `ifr_traas_single_plan` as plan
LEFT JOIN `ifr_plan_tag`  as tag
ON  plan.id = tag.plan_id 
GROUP BY domain 
ORDER BY domain DESC
