在SQL中计算重复值

Question

我有以下信息

Game_id | Team
47      | 1
47      | 1
23      | 2
31      | 1
41      | 2
47      | 8

我想计算所有比赛中的每队数。

我希望它是这样的：

Team 1 has made 3 goals
Team 2 has made 2 goals
Team 8 made 1 goal.

我该怎么做？

Answer 1

使用COUNT()和GROUP BY，例如：

SELECT Team, COUNT(Team) FROM myTable GROUP BY Team
