如何在连接条件上选择特定值？

我有一个包含比赛细节的表，这个表叫做match，每场比赛可以有 n 个目标，这些目标存储在表中goal。

假设我有以下情况match：

id = 2564824
home_team_half_time_score = 2
home_team_score = 4
away_team_half_time_score = 0
away_team_score = 0

所以这个记录意味着match主队以4-0结束，我想知道的是：我如何才能获得goals第一次得分？在这种情况下，第一次有 2 个进球，并且有这个 id：

id    | match_id | result | minute 
16092   2564824    1 - 0     15
16093   2564824    2 - 0     43
16094   2564824    3 - 0     63
16095   2564824    4 - 0     78

我只需要获取minute每个目标的字段，如何设置查询？

架构

Thanks for any help.

更新

实际查询：

$query = "SELECT m.*,
  t.name AS team_name,
  t.id AS team_id,
  l.position AS team_rank,
  COUNT(CASE WHEN g.type = 5 THEN 1 END) AS failed_to_score,
  FROM `match` m
  LEFT JOIN goal g ON m.id = g.match_id
  LEFT JOIN team t ON t.id = :team_id
  LEFT JOIN league_ranking l ON l.team_id = :team_id AND l.round_id = :round_id
  WHERE m.round_id = :round_id
  AND m.status = 5 ";

莱里奥·法耶塔

SELECT minute, result FROM goal WHERE (CAST(minute AS UNSIGNED)<=45 OR minute like '45%') AND match_id='2564824'

如果这是您的起点：

id    | match_id | result | minute 
16092   2564824    1 - 0     15
16093   2564824    2 - 0     43
16094   2564824    3 - 0     63
16095   2564824    4 - 0     78

如果这确实是您的预期结果，那么您必须显示输入数据才能获得此结果

未经测试

SELECT m.*,
  t.name AS team_name,
  t.id AS team_id,
  l.position AS team_rank,
  COUNT(CASE WHEN g.type = 5 THEN 1 END) AS failed_to_score,
  g.minute
  FROM `match` m
  LEFT JOIN goal g ON m.id = g.match_id
  LEFT JOIN team t ON t.id = :team_id
  LEFT JOIN league_ranking l ON l.team_id = :team_id AND l.round_id = :round_id
  WHERE m.round_id = :round_id
  AND m.status = 5 "
  AND (CAST(minute AS UNSIGNED)<=45 OR minute like '45%');

此集成查询将停止对上半场每场比赛的分析。我会将这两个查询分开
