我在这个主题之前问过这个问题请仔细阅读 sql-print-many-word-between-every-columns-with-many-conditions

但是这个问题和前一个问题之间的差异,我想让许多俱乐部的名字中的一个集体选手或一组球员,例如：

El Ahly俱乐部的名字有12个玩家,我想把它分成3个队,每个队有4个球员,我想计算每个俱乐部名字里面有多少球队
然后把它们放在不变的数字(组)中4 8 16 32 64 128 256基于团队打印**任何一个WORD **之间他们之间的东西,过滤数据后,选择full_name,club_name从玩家其中y_of_birth = 2000所需的输出应该是这样的：

在这个例子中,有两组** ANY WORD **,因为它是一个6组,并将它们放在8个不变的组中,发现在4或8或16或32或64或128或256个数字之间,而没有相邻2 **任何一个字**或两个相邻的club_name

例子：

4名玩家作为一名球员

如果结果选择full_name,club_name从玩家,其中y_of_birth = 2000是12个玩家,这意味着12个玩家= 3组,因为每个组有4个玩家下一步打印**任何一个字** 4次(注意：**任何一个字**是这些组之一)在3组之间,所以输出将是这样的：

+----+------+---------------------+
|   full_name  |  club_name       |
+--------------+------------------+
| Ahmed Sayed  |   El Ahly        |
+--------------+------------------+
| Kareem Gaber |   El Ahly        |
+--------------+------------------+
| Maher Zein   |   El Ahly        |
+--------------+------------------+
| Mohab Saeed  |   El Ahly        |
+----+------+--+------------------+
| ahmed shawky |   Petroget       |

+--------------+------------------+
| moataz Gamal |   Petroget       |
+------+-------+------------------+
| **ANY WORD** |                  |

| omar galal   |   El Ahly        |
+--------------+------------------+
| Kamal saber  |   El Ahly        |
+--------------+------------------+

结论：

4 8 16 32 64 128 256是不可变组

组4应该用16个玩家填写**任意一个字,**之间没有相邻的东西：

+----+------+---------------------+
|   full_name  |  club_name       |
+--------------+------------------+
| Ahmed Sayed  |   El Ahly        |
+--------------+------------------+
| Kareem Gaber |   El Ahly        |
+--------------+------------------+
| Maher Zein   |   El Ahly        |
+--------------+------------------+
| Mohab Saeed  |   El Ahly        |
+----+------+--+------------------+
| ahmed shawky |   Petroget       |

+------+-------+------------------+
| **ANY WORD** |                  |

| omar galal   |   El Ahly        |
+--------------+------------------+
| Kamal saber  |   El Ahly        |
+--------------+------------------+

第8组应该填充32名玩家,** **任意一个字,**之间没有相邻的东西：

+----+------+---------------------+
|   full_name  |  club_name       |
+--------------+------------------+
| Ahmed Sayed  |   El Ahly        |

编辑：

我从Gordon Linoff得到这个查询

select p.*
from (select p.*,(@rn := if(@c = club_name,@rn + 1,if(@c := club_name,1,1)
                       )
             ) as seqnum
      from players p cross join
           (select @c := '',@rn := 0) params
      order by club_name
     ) p
order by floor((seqnum - 1) / 4),club_name

结合数据过滤后：

select p.*
from (select p.full_name,club_name,1)
                       )
             ) as seqnum
      from players p  cross join
           (select @c := '',@rn := 0) params  WHERE `y_of_birth` LIKE N'%2000%'

      order by club_name
     ) p 

order by floor((seqnum - 1) / 4),club_name

输出如下内容：

+----+------+---------------------+

任何帮助将不胜感激！

我读过你以前的帖子和这个.如果我得到这个想法,基本的事情是你有团队,你有球员,你想要在某些标准化组合(即说话)中显示数据.

那么有一个常数,你总是比较哪个是团队的大小.

我会做一个子查询,将团队的数量统计为玩家,并按以下方式使用它：

select t.*,x.total_players
       --,row_number() over(order by t.team_name) row_id
from team_table t
    join (
          select team_id,count(1) total_playerss
          from team_table 
          group by team_id
         ) x on x.team_id = t.team_id
order by t.team_name

当回显出PHP中的结果集时,您可以构建一些功能,如：

<?php

function add_some_word($playerCount) {

if ($playerCount >4 && $playerCount <= 8) {
echo '*** SOME WORD***';
echo '*** SOME WORD***';
echo '*** SOME WORD***';
}
else if ($playerCount >4 && $playerCount <= 8) {
echo '*** SOME WORD***';
echo '*** SOME WORD***';
}
// etc.
}

?>

使用结果集中的row_id,您可以看到一个团队何时开始和结束.

所以当它吐出行时,它可能是这样的：

<?php

$currentTeamName = "";

while ($row = pg_fetch_array($result,null,PGSQL_ASSOC)) {
// echo data you would normally send out

if ($currentTeamName != $row['team_name']) {
add_some_word($row['total_players']);
}

}

?>

我希望得到你的问题.我快速冲破这个,但我认为这将有所帮助！
