我希望能够在表中找到一列相同但另一列不同的事件。

示例表：

id    team    week
1     1       1
1     2       1
2     2       1
2     1       2

我想要一个查询，该查询将找到所有团队不同但周仍然相同的 ID，因此团队不等于团队，但周等于周。

基本上我想知道是否有任何 id 在同一周内更换了团队，我该怎么做？

    t1.week
FROM 
    YourTable t1
    JOIN YourTable t2 
        ON t1.ID = t2.ID
        AND t1.team < t2.team
        AND t1.week = t2.week

SELECT ID
, COUNT(DISTINCT TEAM) AS CNT_TEAM
, COUNT(DISTINCT WEEK) AS CNT_WEEK
FROM TABLENAME
GROUP BY ID
HAVING COUNT(DISTINCT TEAM) > 1
AND COUNT(DISTINCT WEEK) = 1

像这样的东西？

SELECT distinct id
FROM TeamWeek
GROUP BY id, week
HAVING Count(team) > 1
