对不同公司的团队进行排序

Question

我有一个用于在不同公司的团队之间生成匹配的数据库。

例子：

• A公司有团队：team1、team2、team3
• B 公司有团队：comp1、comp2
• C 公司有团队：companyc
• 公司 D 有团队：companyd1, companyd2

我必须生成球队之间的比赛，例如球队 1 不能与球队 2 一起比赛，因为是同一家公司。

我有这部分，但其他要求是他们可以连续比赛，例如如果第一场比赛是team1 vs comp1，第二场比赛应该是company c vs companyd。我怎样才能让同一支球队没有连续比赛？

这是我尝试的查询

select Cotejos.id_pelea, Partido1, Nombre1, Partido2, Nombre2,
 ronda = ROW_NUMBER() OVER(partition by Partido1 order by Partido1) 
  from Cotejos 
order by  ronda, newid()

按 partido1 的顺序给我结果，但 partido 2 在同一个 ronda 中重复

例如，命令是这样的

  Partido1    Nombre1              Partido2    Nombre2              ronda
----------- -------------------- ----------- -------------------- ----------
58          JJ Y LA ESTRELLA 2   1           AZTECA LAGUNA 3      1
123         LA JOYA 3            1           AZTECA LAGUNA 3      1
141         EL MILAGRO 2         1           AZTECA LAGUNA 1      1
2           GREGORIO GARCIA      3           CHICHO 1             1
5           GUARDADO 1           11          MA LUISA 2           1
119         GUARDADO 2           11          MA LUISA 3           1
14          RIELEROS Y CUMBRES 2 13          COMPADRES Y 28 DE OC 1

我喜欢这样的东西

 Partido1    Nombre1              Partido2    Nombre2          ronda
----------- ----------- -------------------- ----------- -------------------
   58          JJ Y LA ESTRELLA 2   1           AZTECA LAGUNA 3      1
   2           GREGORIO GARCIA      3           CHICHO 1             1
   5           GUARDADO 1           11          MA LUISA 2           1
   123         LA JOYA 3            1           AZTECA LAGUNA 3      2
   14          RIELEROS Y CUMBRES 2 13          COMPADRES Y 28 DE OC 2
   119         GUARDADO 2           11          MA LUISA 3           2
   141         EL MILAGRO 2         1           AZTECA LAGUNA 1      3

Answer 1

以下内容会有所帮助。注意我借用了endo64SQL Server Random Sort中的答案

设置：

CREATE TABLE Table1
    ([Team] varchar(9), [Company] varchar(1))
;

INSERT INTO Table1
    ([Team], [Company])
VALUES
    ('team1', 'a'),
    ('team2', 'a'),
    ('team3', 'a'),
    ('comp1', 'b'),
    ('comp2', 'b'),
    ('companyc', 'c'),
    ('companyd1', 'd'),
    ('companyd2', 'd')
;

查询：

select
*
from (
    select
        t1.company t1company
      , t1.team    t1team
      , t2.company
      , t2.team
      , CAST(CHECKSUM(NEWID(), t1.team + t2.team) & 0x7fffffff AS float) x
      , row_number() over(partition by t1.company, t1.team order by t2.company, t2.team) y
    from table1 t1
    inner join table1 t2 on t1.company <> t2.company
    ) d
order by x,y
;

示例结果：
