SqlServer 递归查询树形数据

由 一曲冷凌霜 提交于 2020-01-13 12:54:11
一直没有在意过数据库处理树形数据的重要性，直到有一天朋友问起我关于树形数据查询的问题时才发现根本不会，正好这个时候也要用到递归进行树形数据的查询于是在网上查了一圈,语法总结如下 参考文献：https://msdn.microsoft.com/query/dev10.query?appId=Dev10IDEF1&l=ZH-CN&k=k(WITH_TSQL);k(SQL11.SWB.TSQLRESULTS.F1);k(SQL11.SWB.TSQLQUERY.F1);k(MISCELLANEOUSFILESPROJECT);k(DevLang-TSQL)&rd=true 一：简单的树形数据 代码如下： -- with一个临时表(括号中是你要查询的列名) with temp(ID,PID,Name,curLevel) as ( --1：初始查询（这里的PID=-1 在我的数据中是最底层的根节点） select ID,PID,Name,1 as level from dbo.T_ACL_OU where Deleted = 0 and PID = -1 union all --2：递归条件 select a.ID,a.PID,a.Name, b.curLevel+1from T_ACL_OU a --3：这里的临时表和原始数据表都必须使用别名，不然递归的时候不知道查询的是那个表的列

Recursively set permissions on folders using Powershell?

由 ≯℡__Kan透↙ 提交于 2020-01-11 11:04:57
问题 I have a directory which I want to go through recursively and set permissions on all the folders. So the order of operations should be: Remove all ACL from folder Add ACL to folder Set ACL I tried the below code, but I am getting the error Cannot set the ACL because the method that it needs to invoke, SetSecurityDescriptor, does not exist. foreach ($folder in Get-ChildItem -Path c:\perms -Recurse -Directory) { $AccessRule = New-Object System.Security.Accesscontrol.FileSystemAccessRule ("user"

How do I set ACL for a Windows Service in .net?

由 穿精又带淫゛_ 提交于 2020-01-11 06:23:12
问题 I have a service that I need to be able to start and stop with a button. I am using a ServiceController in a seperate program and everything works as intended when I run this seperate program as an administrator. However, I need to be able to control this service as anyone. How can I set the permissions for my service so that everyone has full control of it? This needs to be done programatically as either part of the service, or the install. It is a localservice written in vb.net. 回答1: You

Apache Rocketmq 权限控制（七）

由 萝らか妹 提交于 2020-01-10 14:02:53
权限控制 1.权限控制特性介绍 权限控制（ACL）主要为RocketMQ提供Topic资源级别的用户访问控制。用户在使用RocketMQ权限控制时，可以在Client客户端通过 RPCHook注入AccessKey和SecretKey签名；同时，将对应的权限控制属性（包括Topic访问权限、IP白名单和AccessKey和SecretKey签名等）设置在distribution/conf/plain_acl.yml的配置文件中。Broker端对AccessKey所拥有的权限进行校验，校验不过，抛出异常； ACL客户端可以参考： org.apache.rocketmq.example.simple 包下面的 AclClient 代码。 2. 权限控制的定义与属性值 2.1权限定义 对RocketMQ的Topic资源访问权限控制定义主要如下表所示，分为以下四种 权限 含义 DENY 拒绝 ANY PUB 或者 SUB 权限 PUB 发送权限 SUB 订阅权限 2.2 权限定义的关键属性 字段 取值 含义 globalWhiteRemoteAddresses *;192.168.*.*;192.168.0.1 全局IP白名单 accessKey 字符串 Access Key secretKey 字符串 Secret Key whiteRemoteAddress *;192.168.*.*

问题 I am implementing a simple database system. Basically is a simple social network, everyone has his own dashboard, where you can post some random text. The problem is that I want a privacy level, I mean I want that somebody is allowed to browse only some profiles. And I'm deciding who can watch what. The question is: How can I do that?I have to work with relation in the database or what? Thanks for your time. S. 回答1: What you are looking for is called "Access Control List" (ACL): Check out

华为S5700系列交换机使用高级ACL限制不同网段的用户互访

由 允我心安 提交于 2020-01-07 14:00:14
图1 使用高级ACL限制不同网段的用户互访示例 组网需求 如图一所示，某公司通过Switch实现各部门之间的互连。为方便管理网络，管理员为公司的研发部和市场部规划了两个网段的IP地址。同时为了隔离广播域，又将两个部门划分在不同VLAN之中。现要求Switch能够限制两个网段之间互访，防止公司机密泄露。 配置思路 采用如下的思路在Switch上进行配置： 配置高级ACL和基于ACL的流分类，使设备可以对研发部与市场部互访的报文进行过滤。 配置流行为，拒绝匹配上ACL的报文通过。 配置并应用流策略，使ACL和流行为生效。 操作步骤 配置接口所属的VLAN以及接口的IP地址 #创建VLAN10和VLAN20。 <HUAWEI> system-view [HUAWEI] sysname Switch [Switch] vlan batch 10 20 #配置Switch的接口GE1/0/1和GE1/0/2为trunk类型接口，并分别加入VLAN10和VLAN20。 [Switch] interface gigabitethernet 1/0/1 [Switch-GigabitEthernet1/0/1] port link-type trunk [Switch-GigabitEthernet1/0/1] port trunk allow-pass vlan 10 [Switch
