我想在 oracle 中得到以下输出。

Name     |Date of Joining    |Code  |Total Paid(advance+deposit) |Total Present
Navneet  |12 March,2017      |2     |3000                        |3
Ashutosh |12 March,2017      |3     |2000                        |0
Bitu     |12 March,2017      |4     |1500                        |0
Rashmi   |15 March,2017      |5     |4600                        |1
Komal    |16 March,2017      |6     |12000                       |1

我无法编写查询。我必须将三个 table 与求和和计数函数合并。尝试了一切但失败了。你能帮帮我吗？

已尝试查询：

SELECT pr.NAME, 
       pr.date_phy, 
       pr.disease 
FROM   physiofit_registration pr 
       LEFT JOIN (SELECT Sum(amount) totalAmount 
                  FROM   physiofit_amt_deposit 
                  GROUP  BY code) pd 
              ON pr.code = pd.code 
       LEFT JOIN (SELECT Count(*) totalatten, 
                  FROM   physiofit_attendence 
                  GROUP  BY code) pa 
              ON pr.code = pa.code;

Answer 1

试试下面

SELECT pr.NAME,
       pr.date_phy,
       pr.code,
       pd.totalAmount+pr.advance as TotalPaid,
pa.totalatten as TotalPresent
FROM   physiofit_registration pr
       LEFT JOIN (SELECT code,Sum(amount) totalAmount
                  FROM   physiofit_deposit
           group by code
                  ) pd
              ON (pr.code = pd.code)
          LEFT JOIN (SELECT code,Count(*) totalatten
                  FROM   physiofit_attendence
                  GROUP  BY code) pa
           ON pr.code = pa.code;
