Il semble que vous ayez simplement besoin de modifier votre HAVING
clause, pour filtrer les cas où balance
est soit supérieur à zéro (Débiteur) OU balance
est inférieur à zéro (Créancier).
Vous pouvez également utiliser le conditionnel IF()
expressions pour déterminer dr/cr dans le balance
colonne.
Pour obtenir des débiteurs uniquement :
SELECT client_id,
Sum(Coalesce(CASE
WHEN action_type = 'dr' THEN amount
end, 0)) AS total_debits,
Sum(Coalesce(CASE
WHEN action_type = 'cr' THEN amount
end, 0)) AS total_credits,
Sum(Coalesce(CASE
WHEN action_type = 'cr' THEN amount
end, 0)) - Sum(Coalesce(CASE
WHEN action_type = 'dr' THEN
amount
end, 0)) AS total_debtors,
IF(Sum(Coalesce(CASE
WHEN action_type = 'cr' THEN amount
end, 0)) - Sum(Coalesce(CASE
WHEN action_type = 'dr' THEN
amount
end, 0)) > 0, 'dr', 'cr') AS balance
FROM tbl_balancesheet
GROUP BY client_id
HAVING balance = 'dr' AND total_debtors <> 0
Pour obtenir des créanciers uniquement :
SELECT client_id,
Sum(Coalesce(CASE
WHEN action_type = 'dr' THEN amount
end, 0)) AS total_debits,
Sum(Coalesce(CASE
WHEN action_type = 'cr' THEN amount
end, 0)) AS total_credits,
Sum(Coalesce(CASE
WHEN action_type = 'cr' THEN amount
end, 0)) - Sum(Coalesce(CASE
WHEN action_type = 'dr' THEN
amount
end, 0)) AS total_debtors,
IF(Sum(Coalesce(CASE
WHEN action_type = 'cr' THEN amount
end, 0)) - Sum(Coalesce(CASE
WHEN action_type = 'dr' THEN
amount
end, 0)) > 0, 'dr', 'cr') AS balance
FROM tbl_balancesheet
GROUP BY client_id
HAVING balance = 'cr' AND total_debtors <> 0
