partition over 子句中的错误 "Incorrect syntax near 'order'"

Question

导致此错误的原因是什么？

在 SQL Server 2005 中，我收到错误 'order' 附近的语法错误。我已将错误隔离到 OVER clause（当我删除 'over' 子句中的 'order by' 时错误消失）。我查看了文档并搜索了解决方案，但找不到问题所在。

SELECT bill.[cust_id], MONTH(bill.[del_date]), YEAR(bill.[del_date]),
   SUM(SUM(ISNULL(bill.[sum_count], 0))) OVER (PARTITION BY bill.[cust_id]
   ORDER BY YEAR(bill.[del_date]), MONTH(bill.[del_date])) AS QtyProcessed
FROM EnvelopeBilling bill
WHERE bill.[cust_id] = 1721
  AND bill.[del_date] BETWEEN '5/1/2015' AND '10/31/2015'
GROUP BY bill.[cust_id], MONTH(bill.[del_date]), YEAR(bill.[del_date])
ORDER BY bill.[cust_id], YEAR(bill.[del_date]), MONTH(bill.[del_date])

Answer 1

您不能将 SUM 与 OVER 和 Partition by..Orderby 一起使用，只能与 PARTITION BY 一起使用。点你想加的东西是没有意义的。

SELECT bill.[cust_id], 
       Month(bill.[del_date]), 
       Year(bill.[del_date]), 
       Sum(Sum(Isnull(bill.[sum_count], 0))) 
         OVER (partition BY bill.[cust_id]) AS QtyProcessed 
FROM   envelopebilling bill 
WHERE  bill.[cust_id] = 1721 
       AND bill.[del_date] BETWEEN '5/1/2015' AND '10/31/2015' 
GROUP  BY bill.[cust_id], 
          Month(bill.[del_date]), 
          Year(bill.[del_date]) 
ORDER  BY bill.[cust_id], 
          Year(bill.[del_date]), 
          Month(bill.[del_date])

Answer 2

如果 'partition by' 与 'group by' 相同，您应该可以通过

删除分区

SELECT bill.[cust_id] , MONTH(bill.[del_date]), YEAR(bill.[del_date]),
       SUM(ISNULL(bill.[sum_count], 0)) AS QtyProcessed
  FROM EnvelopeBilling bill
 WHERE bill.[cust_id]= 1721
   AND bill.[del_date] BETWEEN '5/1/2015' AND '10/31/2015'
 GROUP BY bill.[cust_id], YEAR(bill.[del_date]), MONTH(bill.[del_date])
 ORDER BY bill.[cust_id], YEAR(bill.[del_date]), MONTH(bill.[del_date])
