在Simple.Data中使用INSTR（oracle函数）

Question

如何将INSTR与simple.data

一起使用

我需要在加入2个表时添加条件

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    // Register for remote notifications
    if #available(iOS 8.0, *) {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
    } else {
        // Fallback
        let types: UIRemoteNotificationType = [.Alert, .Badge, .Sound]
        application.registerForRemoteNotificationTypes(types)
    }


    FIRApp.configure()
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotificaiton),
                                                     name: kFIRInstanceIDTokenRefreshNotification, object: nil)
}      

 func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                 fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {

    print(userInfo)
}

func tokenRefreshNotificaiton(notification: NSNotification) {
    if let refreshedToken = FIRInstanceID.instanceID().token() {
        print("InstanceID token: \(refreshedToken)")

        User.sharedUser.googleUID = refreshedToken
    }
}


func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forRemoteNotification userInfo: [NSObject : AnyObject], withResponseInfo responseInfo: [NSObject : AnyObject], completionHandler: () -> Void) {

    print(userInfo)
}

    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {

    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Prod)
}

func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forRemoteNotification userInfo: [NSObject : AnyObject], withResponseInfo responseInfo: [NSObject : AnyObject], completionHandler: () -> Void) {

    print(userInfo)
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                 fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {


    print(userInfo)
}

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {

    print("ошибка")
    print(error)
    print(error.description)

}

如何使用Simple.Data（c＃）编写此查询？

Answer 1

如果可以，我现在无法测试，但请尝试：

db.A.FindAll().Join(db.B).On(db.A.Column.INSTR(db.B.Column) > 0);
