ALTER TABLE "APPLICATIONS_SRV_STORAGE"
ADD CONSTRAINT "APPL_SRV_STORAGE_APPLICAT_FK1"
FOREIGN KEY ("APP_ID")
REFERENCES "APPLICATIONS" ("APP_ID")
ON DELETE CASCADE
ENABLE;
Does it mean: When something on table APPLICATIONS is deleted, delte altough the entry in APPLICATION_SRV_STORAGE?
The addition of DELETE CASCADE means that when a row in APPLICATIONS is deleted, any rows in APPLICATIONS_SRV_STORAGE that reference its APP_ID will also be deleted.
