php/SQL - 在许多条件下每4个名字之间打印4次

我之前在这个主题中已经问过这个问题请仔细阅读sql-print-many-word-between-every-columns-with-many-conditions

但是这个问题和之前的问题之间的差异,我想在许多俱乐部名称中建立一个集体球员或一组球员,例如:

El Ahly俱乐部的名字有一个12球员,我想将它拆分成3 teams每个team都有4球员什么,我想看看有多少team每个俱乐部的名字里面,然后把它们不变的数字里面(组)4 8 16 32 64 128 256基础上的数量teams打印**ANY WORD**它们之间以后类似的东西与过滤数据select full_name,club_name from players where y_of_birth=2000的期望的输出应该是这样的:

在这个例子中,2 groups of **ANY WORD**因为它的a 6 group和把它们放在8不可变的组中,它们在4或8或16或32或64或128或256数字中找到......并且在相邻的2 **ANY WORD**或2之间没有相邻的club_name

例子 :

4名球员作为一名球员

如果之后的结果select full_name,club_name from players where y_of_birth=2000是12玩家意味着12 players= 3 groups因为每组都有4玩家下一步打印**ANY WORD**4次(注意:**ANY WORD**是这些组中的一个)在3组之间,所以输出将是这样的:

Answer 1

Wal*_*row 2

我读过你的上一篇文章和这篇文章。如果我明白了这个想法，基本的事情就是你有球队，你有球员，你想以某些标准化分组（可以这么说）显示数据。

嗯，有一个恒定的数据，您总是要与该数据进行比较，即团队的规模。

我要做的是创建一个子查询，将球队与球员数量分组，并以某种方式使用它，如下所示：

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

当在 PHP 中回显结果集时，您可以构建一些函数，例如：

<?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row_id结果集中的，您可以看到团队何时开始和结束。

因此，当它吐出行时，可能会是这样的：”

<?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']);
}

}

?>
