Ajouter la condition IF dans la requête SQL, quelque chose comme ça.
SELECT invoice_details.invoice_no,
invoice_details.invoice_date,
invoice_details.invoice_amount,
SUM(IF(received_amount_details.received_amount IS NULL
OR received_amount_details.received_amount = '', 0.0,
received_amount_details.received_amount)) AS totalreceiptamt
FROM (SELECT DISTINCT invoice_no,
received_amount
FROM received_amount_details) AS received_amount_details
right join invoice_details
ON received_amount_details.invoice_no =
invoice_details.invoice_no
WHERE invoice_details.proje_id = '7'
GROUP BY invoice_details.invoice_no
Cela ajoutera 0,0 car la valeur par défaut n'est pas receive_amount_details.received_amount IS NULL ou vide
Nous effectuons également une jointure droite pour obtenir toutes les valeurs de la page de détails de la facture.
