用于更新查询设置值的选择查询结果不起作用

Question

我在MS Access中有一个更新查询；为设置更新查询的值，我使用了选择查询，我确定其结果是唯一的，但出现错误

override func viewDidLoad() {        

    let tap = UITapGestureRecognizer(target: self, action: #selector(touchHandled))
    view.addGestureRecognizer(tap)


}


@objc func touchHandled() {
    tabBarController?.hideTabBarAnimated(hide: true)
}


extension UITabBarController {
    func hideTabBarAnimated(hide:Bool) {
        UIView.animate(withDuration: 2, animations: {
            if hide {
                self.tabBar.transform = CGAffineTransform(translationX: 0, y: 100)
            } else {
                self.tabBar.transform = CGAffineTransform(translationX: 0, y: -100)
            }
        })
    }

这是我得到的错误：

  

操作必须使用可更新的查询

我的更新查询是这样：

SET asbuilt_list.commented_sheet =
       Nz((SELECT [pages]
           FROM [tbl_transmittal_discipline_poi_max] AS T1
           WHERE (T1.[owner document number] = asbuilt_list.[doc])
             AND (T1.poi = "cmn" )), 0)
