I am getting an SQLCODE=-119 in DB2 - sql

Question

I was converting MySql to DB2 queries, and so far I got to this:
SELECT
loandata.*,
SUM(lc.amount_outstanding_derived) AS chargesDue
FROM
(
SELECT
cl.display_name AS clientName,
cl.id AS clientId,
ln.id AS loanId,
ln.account_no AS accountId,
ln.loan_status_id AS accountStatusId,
pl.short_name AS productShortName,
ln.product_id AS productId,
ln.currency_code AS currencyCode,
ln.currency_digits AS currencyDigits,
ln.currency_multiplesof AS inMultiplesOf,
rc.name AS currencyName,
rc.display_symbol AS currencyDisplaySymbol,
rc.internationalized_name_code AS currencyNameCode,
CASE WHEN ln.loan_status_id = 200 THEN ln.principal_amount
ELSE NULL
END AS disbursementAmount,
SUM(COALESCE((CASE WHEN ln.loan_status_id = 300 THEN ls.principal_amount ELSE 0.0 END), 0.0) - COALESCE(CASE WHEN ln.loan_status_id = 300 THEN ls.principal_completed_derived ELSE 0.0 END, 0.0)) AS principalDue,
ln.principal_repaid_derived AS principalPaid,
SUM(COALESCE(CASE WHEN ln.loan_status_id = 300 THEN ls.interest_amount ELSE 0.0 END, 0.0) - COALESCE(CASE WHEN ln.loan_status_id = 300 THEN ls.interest_completed_derived ELSE 0.0 END, 0.0)) AS interestDue,
ln.interest_repaid_derived AS interestPaid,
SUM(COALESCE(CASE WHEN ln.loan_status_id = 300 THEN ls.fee_charges_amount ELSE 0.0 END, 0.0) - COALESCE(CASE WHEN ln.loan_status_id = 300 THEN ls.fee_charges_completed_derived ELSE 0.0 END, 0.0)) AS feeDue,
ln.fee_charges_repaid_derived AS feePaid
FROM
m_loan LN
JOIN m_client cl ON
cl.id = ln.client_id
LEFT JOIN m_office OF ON
of.id = cl.office_id
AND of.hierarchy LIKE ?
LEFT JOIN m_product_loan pl ON
pl.id = ln.product_id
LEFT JOIN m_currency rc ON
rc.code = ln.currency_code
JOIN m_loan_repayment_schedule ls ON
ls.loan_id = ln.id
AND ls.completed_derived = 0
AND ls.duedate <= ?
WHERE
of.id = ?
AND (ln.loan_status_id = 300)
AND ln.group_id IS NULL
) AS loandata
LEFT JOIN m_loan_charge lc ON
lc.loan_id = loandata.loanId
AND lc.is_paid_derived = 0
AND lc.is_active = 1
AND ( lc.due_for_collection_as_of_date <= ?
OR lc.charge_time_enum = 1)
GROUP BY
loandata.clientId,
loandata.loanId
ORDER BY
loandata.clientId,
loandata.loanId
But I am getting an error :
SQL Error [42803]: An expression starting with "DISBURSEMENTAMOUNT"
specified in a SELECT clause, HAVING clause, or ORDER BY clause is not
specified in the GROUP BY clause or it is in a SELECT clause, HAVING
clause, or ORDER BY clause with a column function and no GROUP BY
clause is specified.. SQLCODE=-119, SQLSTATE=42803, DRIVER=4.26.14
I have tried inserting Group by and Order By clauses each for the select clause items like so:

A gross simplification of your query is:
SELECT loandata.*,
SUM(lc.amount_outstanding_derived) AS chargesDue
FROM (SELECT <lots of columns>
FROM <lots of tables>
. . .
) loandata LEFT JOIN
m_loan_charge lc
ON lc.loan_id = loandata.loanId AND
lc.is_paid_derived = 0 AND
lc.is_active = 1 AND
( lc.due_for_collection_as_of_date <= ? OR lc.charge_time_enum = 1)
GROUP BY loandata.clientId, loandata.loanId
ORDER BY loandata.clientId, loandata.loanId;
You have a SELECT * bringing in lots of columns. Fine. Then you have an aggregation function -- so the query is an aggregation query. Need a GROUP BY with lots of columns.
But I don't find one. I only find a GROUP BY with two columns. And that is an error in SQL. And happily, that is now an error in the more recent versions of MySQL. And in basically every other database.
You need to list all the columns in the GROUP BY that are not aggregated in the SELECT.
