我需要按照父母1及其子女、父母2及其子女的顺序进行描述。

MS SQL Server 2017架构设置：

CREATE TABLE myproblem (
   id int,
   parent int);

INSERT INTO myproblem values (5098,0),(5099,5098),(5100,5099),(5101,5099);
INSERT INTO myproblem values (5102,0),(5107,5102);
INSERT INTO myproblem values (5106,0),(5108,5106),(5110,5106);
INSERT INTO myproblem values (5109,0),(5111,5109);
INSERT INTO myproblem values (5112,0);

SELECT ParentUserType.Id As Parent ,count(ChildUserType.Id) AS 'Number of children'
    FROM myproblem AS ChildUserType
    LEFT JOIN myproblem AS ParentUserType ON ChildUserType.Parent = ParentUserType.Id
    GROUP BY ParentUserType.Id
    ORDER BY COUNT(ChildUserType.Id)

| Parent | Number of children |
|--------|--------------------|
|   5098 |                  1 |
|   5102 |                  1 |
|   5109 |                  1 |
|   5106 |                  2 |
|   5099 |                  2 |
| (null) |                  5 |

查询1：

CREATE TABLE myproblem (
   id int,
   parent int);

INSERT INTO myproblem values (5098,0),(5099,5098),(5100,5099),(5101,5099);
INSERT INTO myproblem values (5102,0),(5107,5102);
INSERT INTO myproblem values (5106,0),(5108,5106),(5110,5106);
INSERT INTO myproblem values (5109,0),(5111,5109);
INSERT INTO myproblem values (5112,0);

SELECT ParentUserType.Id As Parent ,count(ChildUserType.Id) AS 'Number of children'
    FROM myproblem AS ChildUserType
    LEFT JOIN myproblem AS ParentUserType ON ChildUserType.Parent = ParentUserType.Id
    GROUP BY ParentUserType.Id
    ORDER BY COUNT(ChildUserType.Id)

| Parent | Number of children |
|--------|--------------------|
|   5098 |                  1 |
|   5102 |                  1 |
|   5109 |                  1 |
|   5106 |                  2 |
|   5099 |                  2 |
| (null) |                  5 |

：

CREATE TABLE myproblem (
   id int,
   parent int);

INSERT INTO myproblem values (5098,0),(5099,5098),(5100,5099),(5101,5099);
INSERT INTO myproblem values (5102,0),(5107,5102);
INSERT INTO myproblem values (5106,0),(5108,5106),(5110,5106);
INSERT INTO myproblem values (5109,0),(5111,5109);
INSERT INTO myproblem values (5112,0);

SELECT ParentUserType.Id As Parent ,count(ChildUserType.Id) AS 'Number of children'
    FROM myproblem AS ChildUserType
    LEFT JOIN myproblem AS ParentUserType ON ChildUserType.Parent = ParentUserType.Id
    GROUP BY ParentUserType.Id
    ORDER BY COUNT(ChildUserType.Id)

| Parent | Number of children |
|--------|--------------------|
|   5098 |                  1 |
|   5102 |                  1 |
|   5109 |                  1 |
|   5106 |                  2 |
|   5099 |                  2 |
| (null) |                  5 |

不要把图像放在这里。。。（除非他们真的把事情说得更清楚，在这种情况下不是这样的…）我之前的评论是想说这个链接更清楚：看起来不错！但是你知道解决我问题的办法吗。请给我一个解决方案您想要订购物品，但不清楚

id

和

Parentx

之间的链接是什么，如果我得到了正确的描述，您想按

Parentx

排序吗？父级可以有一个或多个子级，同样，子级也可以有一个或多个子级。因此，我希望最新的家长及其子女在顶部
