Séquences avec clé primaire composite

INSERT INTO [users]
(business_id, id)
FROM
(
SELECT 
ID - (SELECT MIN(ID) FROM [users] WHERE business_ID = B.ID) AS business_id
,(SELECT MAX(ID)+1 FROM [users] WHERE business_ID = B.ID) AS ID
FROM [businesses] B
)

si vous le liez aux nouvelles entrées que vous ajoutez, il devrait fournir la clé composite

Nouvelle mise à jour :

INSERT INTO [users]
(business_id, id, name)
VALUES
(
3
,ISNULL((SELECT MAX(ID)+1 FROM [users] WHERE business_ID = 3),1) AS ID
,'d'
)
