【问题描述】：

我有一个包含特定比赛的比赛的表格。

当我选择 MatchIDAuto 4050 时，我需要知道这是本次比赛总共 29 场比赛中的第 15 场。

我显然可以通过 Match2 中的简单选择计数 (*) 确定有 29 个匹配项，其中 CompetitionIDAuto = 669

有没有人知道一种无需循环就可以确定的方法，例如 4050 是第 15 场比赛？

【解决方案1】：

我假设您的匹配项始终按升序（按日期）插入，因此第一个匹配项的 MatchIDAuto 最低。

所以试试这个

SELECT m.MatchIDAuto, COUNT( * ) AS row_number
FROM Match2 m
JOIN Match2 m2 ON m.MatchIDAuto >= m2.MatchIDAuto
WHERE m.MatchIDAuto = 4050
GROUP BY m.MatchIDAuto

输出

+-------------+------------+
| MatchIDAuto | row_number |
+-------------+------------+
|        4050 |         15 |
+-------------+------------+
