为一列复杂查询（oracle）选择distinct

这是一个包含as、multiple join、where、counts、max等的查询

我正在为一家血液中心做一份报告，报告将显示去年每位献血者损失了多少血液和血浆。我算出了所有其他的，但它基本上提取了去年每个捐赠者的所有名单。我只想展示最新的。我有MAX on date，等等，并尝试在捐赠者ID上使用Distinct，甚至只根据捐赠者ID进行分组（它不允许我，错误）

我正在使用Oracle

        SUM(ddlpls.COLLECTION_AMOUNT_LOSS) AS PlasmaLoss FROM    DONOR_VISIT dv INNER JOIN
