sum of two columns in two tables mysql - mysql

Question

i am developing a LMS system for an institute
and i am trying to develop a recovery report on the end of month
the report contains student name total fee package, total received, total receiveable, current month pending installment
here is the installment data of a student with his admission id
and this is the ledger data from where ican pick the fee package and total receiveable fees
and i am using this query for recovery report
SELECT
SUM(l.dr)-SUM(l.cr) as sum_remaining,
f.dr as fee_package,
SUM(i.payment) as this_month_install,
a.reg_id, s.fname
FROM
ledger l, ledger f, student_data s,
admissions a LEFT OUTER JOIN installments i ON a.admissionid = i.admissionid
WHERE
a.admissionid = '58ac4b5421488' AND
a.reg_id = s.reg_id AND
l.reference = '58ac4b5421488' AND
l.details <> 'registration fee' AND
f.reference = '58ac4b5421488' AND
f.details = 'Fee Package' AND
i.install_no <> '1' AND
MONTH(i.pay_date) = '04' AND
YEAR(i.pay_date) = '2017'
GROUP BY a.admissionid
and its giving the result like this
but the result should be like
sum_remaining = 10000
and this_month_install = 10000
please help me to sort out this problem
Thanks in advance

Answer 1

you should start from admission and use inner join for the others table (left join for installments)
SELECT
SUM(l.dr)-SUM(l.cr) as sum_remaining,
f.dr as fee_package,
SUM(i.payment) as this_month_install,
a.reg_id,
s.fname
FROM admissions a
Inner JOIN ledger f ON f.reference = a.admissionid AND f.details = 'Fee Package'
INNER JOIN ledger l ON l.reference = a.admissionid AND l.details <> 'registration fee'
INNER JOIN student_data s ON a.reg_id = s.reg_id
LEFT JOIN installments i ON a.admissionid = i.admissionid AND i.install_no <> '1'
WHERE a.admissionid = '58ac4b5421488'
AND MONTH(i.pay_date) = '04'
AND YEAR(i.pay_date) = '2017'
GROUP BY a.admissionid
you have two row in installments table that match .. try filter just one
SELECT
SUM(l.dr)-SUM(l.cr) as sum_remaining,
f.dr as fee_package,
SUM(i.payment) as this_month_install,
a.reg_id,
s.fname
FROM admissions a
Inner JOIN ledger f ON f.reference = a.admissionid AND f.details = 'Fee Package'
INNER JOIN ledger l ON l.reference = a.admissionid AND l.details <> 'registration fee'
INNER JOIN student_data s ON a.reg_id = s.reg_id
LEFT JOIN installments i ON a.admissionid = i.admissionid
AND i.install_no not in ( '1', '2')
WHERE a.admissionid = '58ac4b5421488'
AND MONTH(i.pay_date) = '04'
AND YEAR(i.pay_date) = '2017'
GROUP BY a.admissionid

Answer 2

i have done this with a sub query
thanks all
select a.admissionid, s.fname,
sum(l.dr)-SUM(l.cr) as sum_remaining, i.*,
f.dr as fee_package from student_data s,
ledger l, ledger f, admissions a
RIGHT outer join (select admissionid,
sum(payment) as this_month_install
from
installments g where g.install_no <> '1' and MONTH(g.pay_date) = '04' and YEAR(g.pay_date) = '2017' group by g.admissionid) i
ON
i.admissionid = a.admissionid where a.reg_id = s.reg_id and
a.status = 'studying' and a.course = 'PH' and
a.campus = 'CIFSD01' and l.reference = a.admissionid and
l.details <> 'registration fee' and f.reference = a.admissionid
and f.details = 'Fee Package' GROUP BY a.std_id
