在整个数据列表中计算一行

我有一张表格，其中包含特定比赛的比赛。

当我选择MatchIDAuto 4050时，我需要知道这是本场比赛共29场比赛的第15场比赛。

我显然可以确定29场比赛只有来自Match2的简单选择计数（*），其中CompetitionIDAuto = 669

有没有人知道如何确定而不需要循环，例如4050是匹配15？

答案 0 :(得分：0)

我假设你的比赛总是以升序（按日期）插入，这样第一场比赛就有最低的MatchIDAuto。

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 |
+-------------+------------+
