pourquoi ma requête ne fonctionne pas

Question

Je reçois un travail pour joindre les données de plusieurs tables. Une partie de celle-ci est faite avant qui contient une «union». Maintenant, je dois obtenir des données de la table 'migrated_loan_account'. Donc je l'ai rejoint. Mais quand j'ajoute le champ ça ne marche pas. Quand je commente ces 4 champs cela fonctionne. Je ne comprends pas quoi faire. Quelqu'un peut-il m'aider s'il vous plaît?! Voici mon code ci-dessous:

lorsque je commente les champs suivants cela fonctionne. S'il vous plaît aider dépêchez-vous ...

/*, ifnull(migrated_loan_account.outstanding_balance, 0) as radar_loan_due 
        , ifnull(migrated_loan_account.principal_outstanding, 0) as radar_principal_outstanding 
        , ifnull(migrated_loan_account.interest_realizable, 0) as radar_interest_realizable 
        , ifnull(migrated_loan_account.overdue_amount, 0) as radar_overdue_amount*/ 

Answer 1

Si vous commentez ces champs out ça marche? Avec ces champs décommentés, les avez-vous dans votre UNION? Les syndicats doivent retourner le même nombre de colonnes.

Ajouter ce qui suit à la 2ème requête de votre UNION:

, 0 AS radar_loan_due 
, 0 AS radar_principal_outstanding 
, 0 AS radar_interest_realizable 
, 0 AS radar_overdue_amount
