问题：按照参考文档操作，两种方式都不能删除Todo对象，但是会打印删除成功的信息。

参考文档：删除对象1

//    删除对象
//    假如某一个 Todo 完成了，用户想要删除这个 Todo 对象，可以如下操作：
    private func mothod1001_deleteObject() {
        let todo = LCObject(className: "Todo", objectId: "155c6aad6f19a27c001aa6b065")
        
        // 调用实例方法删除对象
        _ = todo.delete { result in
            switch result {
            case .success:
                print("Todo Object delete success")
                break // 删除成功
            case .failure(let error):
                print(error)
            }
        }
    }

//    使用 CQL 语法删除对象
//    LeanStorage 提供了类似 SQL 语法中的 Delete 方式删除一个对象，例如删除一个 Todo 对象可以使用下面的代码：
    private func mothod1101_deleteObject() {
        // 执行 CQL 语句实现删除一个 Todo 对象
        _ = LCCQLClient.execute("delete from Todo where objectId='155c6aad6f19a27c001aa6b065'") { result in
            switch result {
            case .success:
                print("Todo Object delete success")
                break // 删除成功
            case .failure(let error):
                print(error)
            }
        }
    }

刷新页面了记录还在，而且可以在页面手工删除数据！

这条数据到底是否可以删除？
当前行数据视图是锁定图标
下面的write属性又是true
两者看起来矛盾
