plsql - PL/SQL：如何编写这个程序？

Question

我有 3 列：“GAME”“PLAYER_ID”“MINUTES_PLAYED”

看起来像这样：

GAME     ID     MINUTES_PLAYED
12550788  229569   23
12500788  393438   4
12500788  458730   25
12500782  229569   10

我想找到每场比赛的总上场时间，即

ID       TOTAL_MINUTES
229569   33
.
.
.

先感谢您！

Answer 1

select id, sum(minutes_played) from tableName group by id

Answer 2

SELECT ID, SUM(MINUTES_PLAYED)
FROM MYTABLE
GROUP BY ID

Answer 3

只需将它们相加：

SELECT ID, SUM(MINUTES_PLAYED) AS TOTAL_MINUTES
FROM table GROUP BY ID
