I am not able to write a query. I have to merge three tables with sum and count function. Tried every thing but failed. Could you please help me ?

Query tried:

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

try below

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;
