Utilisation d'une instruction Case dans la section values d'une instruction Insert

Veuillez pardonner mon ignorance et mes faibles compétences en programmation SQL, mais je suis normalement un développeur SQL de base.Utilisation d'une instruction Case dans la section values d'une instruction Insert

J'ai besoin de créer un déclencheur hors de l'insertion de données dans une table pour insérer des données différentes dans une autre table.

Dans ce déclencheur, j'ai besoin d'insérer certaines données dans la nouvelle table en fonction des valeurs dans les données nouvellement insérées de la table d'origine. Je suis totalement confus à ce sujet. Je pensais que je serais créatif et utiliserais une déclaration de cas dans la section Valeurs, mais ça ne fonctionne pas.

Quelqu'un peut-il m'aider s'il vous plaît à ce sujet? (Ci-dessous est le code pour le déclencheur que j'ai dès maintenant)

INSERT INTO dbo.WebOnlineUserPeopleDashboard 
    (
     ONLINE_USERACCOUNT_ID,

** NE JAMAIS coder un déclencheur pour l'insertion unique ** il finira par vous mordre! peut-être que vous n'en insérez qu'une seule aujourd'hui, qu'en est-il dans le futur, peut-être un an pour l'instant vous aurez un script inséré un tas ou vous importerez un fichier, etc. ** votre déclencheur de réponse sélectionné n'échouera pas une erreur et une annulation, mais vous obtiendrez juste des données fausses, ce qui est bien pire! ** –

Quelque chose comme ça?

Oh ok, alors utilisez une instruction IF ELSE pour encapsuler l'ensemble des instructions d'insertion. Complètement compréhensible et logique. Je vais essayer de le faire demain matin quand je serai de retour au bureau et je vous le ferai savoir. Merci beaucoup. – mattgcon

Si vous insérez plusieurs lignes à la fois, ce déclencheur échouera. –

Cela a parfaitement fonctionné Merci, Cette table est un processus d'insertion d'une seule rangée, donc je ne vais pas avoir à vous en soucier pour le moment. Dans mes autres tables, je devrais peut-être utiliser l'autre exemple pour les insertions de lignes multiples. – mattgcon

ce traitera toutes les lignes si plusieurs lignes sont affectées par le déclencheur:
