具有两种不同连接和计数的 MYSQL 查询

Question

我有两个单独运行良好的不同查询。第一个给了我有用的结果列 TOTALI和第二个查询列 RIMBORSATI 。因此，我需要将第一个查询与第二个查询合并，并使第一个查询的 HAVING 子句是类似 HAVING totali-rimborsati < professionisti.limite 的操作。 .

非常感谢你。

第一个查询:

SELECT professionisti.*,COUNT(contatti_acquistati_addebito.email) AS totali  
FROM professionisti
   LEFT JOIN contatti_acquistati_addebito ON
             professionisti.email = contatti_acquistati_addebito.email
           AND contatti_acquistati_addebito.DATA
               BETWEEN ('2014-05-01') AND  ('2014-05-31')
   WHERE professionisti.categoria LIKE '%0540%' AND 
         professionisti.province LIKE '%MI%'  
         AND   professionisti.addebito='1'
GROUP BY professionisti.email
HAVING totali  < professionisti.limite
ORDER BY totali ASC LIMIT 4

第二个查询:

SELECT professionisti.*,COUNT(contatti_rimborsi.email) AS rimborsati  
FROM professionisti
LEFT JOIN contatti_rimborsi ON professionisti.email = contatti_rimborsi.email AND 
            contatti_rimborsi.DATA BETWEEN ('2014-05-01') AND  ('2014-05-31')
WHERE professionisti.categoria LIKE '%0540%'
      AND professionisti.province LIKE '%MI%'  
      AND professionisti.addebito='1'
GROUP BY professionisti.email
ORDER BY totali ASC LIMIT 4

Answer 1

select sq1.*,sq2.rimborsati  
from 
(SELECT professionisti.email as email, professionisti.categoria as categoria,professionisti.province as province,professionisti.addebito as addebito, COUNT(contatti_acquistati_addebito.email) AS totali  
FROM professionisti
   LEFT JOIN contatti_acquistati_addebito ON
             professionisti.email = contatti_acquistati_addebito.email
           AND contatti_acquistati_addebito.DATA
               BETWEEN ('2014-05-01') AND  ('2014-05-31')
   WHERE professionisti.categoria LIKE '%0540%' AND 
         professionisti.province LIKE '%MI%'  
         AND   professionisti.addebito='1'
GROUP BY professionisti.email
HAVING totali  < professionisti.limite
ORDER BY totali ASC LIMIT 4) sq1,

(SELECT professionisti.email as email, professionisti.categoria as categoria,professionisti.province as province,professionisti.addebito as addebito, COUNT(contatti_rimborsi.email) AS rimborsati  
FROM professionisti
LEFT JOIN contatti_rimborsi ON professionisti.email = contatti_rimborsi.email AND 
            contatti_rimborsi.DATA BETWEEN ('2014-05-01') AND  ('2014-05-31')
WHERE professionisti.categoria LIKE '%0540%'
      AND professionisti.province LIKE '%MI%'  
      AND professionisti.addebito='1'
GROUP BY professionisti.email
ORDER BY totali ASC LIMIT 4) sq2
where sq1.email=sq2.email and totali <rimborsati
