目前正在编写一个显示大量信息的SQL Server查询，目前它正在吐出正确的信息，但是大块的信息是重复的，有些区域应该组合在一起。请注意，StateAcronym部分实际上是新的 - 在添加StateAcronym之前它都是hunky dory，但是它会全部重复/非组合 - 就像。

我理解为什么它有点偏离，因为相同的区域可以分配给不同的StateAcronyms，但我不确定为什么它仍然显示多个并且没有组合信息
答案 0 :(得分：0)
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
在这种情况下进行的一个简单测试就是运行一个子查询，限制为单个ZoneName，我打赌如果你运行：
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StateAcronym值不同，您将获得超过1行。
