Sql 消除重复和合并信息

目前正在编写一个SQL Server查询，其中显示了一大堆信息，目前正在输出正确的信息，但大部分信息是重复的，某些区域应该合并。请注意，

StateAcronym

部分实际上是一个新的部分-在添加

StateAcronym

之前，它工作得很好，但随后它就完全重复/不合并了-类似于

我的代码：

       ZoneID INT,
   ZoneName VARCHAR(100),
   StateAcronym VARCHAR(5),

   SELECT DISTINCT
    z.ZoneID,
    ISNULL(z.ZoneName,'NO ZONE'),
    (case when z.ZoneName is not null and z.ZoneName <> 'No Zone'
          then st.StateAcronym
    else null
        end) as StateAcronym,

我理解为什么会有点不对劲，因为同一个区域可以分配给不同的州首字母缩略词，但我不确定为什么它仍然显示多个，并且不合并信息。如果查看输出，您会发现实际上没有任何重复项

我猜您的子查询返回了多个

StateAcronym

值，因此需要将

JOIN

条件更改为：

ON t.ZoneName = f.ZoneName
 AND t.StateAcronym = f.StateAcronym

在这种情况下，一个简单的测试是运行一个子查询，仅限于一个

ZoneName

，我打赌如果您运行：

SELECT 
    ZoneName,
    StateAcronym,
    COUNT(distinct SiteID) TotalSites,
    SUM(distinct Papers) TotalPapers,
    SUM(distinct Papers)*100.0/(SELECT SUM(distinct Papers) FROM @BulkInfo) TotPer
FROM  @BulkInfo
WHERE ZoneName = 'ZoneName1'
GROUP BY ZoneName,StateAcronym

---

由于不同的

StateAcronym

值，您将得到不止一行。

我在提供的示例输出中没有看到重复项。我想我是想使用不同的单词，但从技术上讲，我希望看到的是两行带有ZoneName1 | NJ。。。。以及宾夕法尼亚州第1区。。。。。我不确定为什么某些区域产生不同的数字，并且没有将信息合并到一个不同的行中。对于

TotalSitesType2

，对于

ZoneName1

，有两个不同的值，这是为什么？

SELECT 
    ZoneName,
    StateAcronym,
    COUNT(distinct SiteID) TotalSites,
    SUM(distinct Papers) TotalPapers,
    SUM(distinct Papers)*100.0/(SELECT SUM(distinct Papers) FROM @BulkInfo) TotPer
FROM  @BulkInfo
WHERE ZoneName = 'ZoneName1'
GROUP BY ZoneName,StateAcronym
