sql - 选择 Distinct 并获取计数

Question

我需要从表中获取唯一记录并获取它们的重复次数。我有疑问：

SELECT AwardReference.ownerID
FROM AwardReference
WHERE AwardReference.ownerType = 'song';

这会返回类似：

ownerID
    1
    2
    4
    4
    5
    5
    5

我需要得到类似的东西：

ownerID  count
    1     1
    2     1
    4     2
    5     3

有谁知道该怎么做？

我也必须用 MS ACCESS 完成这项任务......

SELECT  AwardReference.ownerID ,
        COUNT(*) AS count
FROM    AwardReference
WHERE   AwardReference.ownerType = 'song'
GROUP BY AwardReference.ownerID
