SELECT * FROM ((SELECT SUM(money) total_money,agentid user_id FROM dcr_declaration GROUP BY agentid) a1 ) 
UNION ALL
SELECT * FROM ((SELECT SUM(agent_level_money) total_money,user_id FROM dcr_user_recommend_log GROUP BY user_id) a2 );


-- 两张表分组查询之后 再合并结果并且分组查询

SELECT * FROM ((SELECT SUM(money) total_money,agentid user_id FROM dcr_declaration GROUP BY agentid) a1 ) 
UNION ALL
SELECT * FROM ((SELECT SUM(agent_level_money) total_money,user_id FROM dcr_user_recommend_log GROUP BY user_id) a2 )
