错误＆＃34;错误的语法在＆＃39; order＆＃39;＆＃34;附近在partition over子句中

Question

有人能告诉我导致此错误的原因吗？

在<g:each var="game" in="${games}"> <!-- Render game --> <g:each var="category" in="${game.categories}"> <!-- Render the game's category --> </g:each> </g:each> 中，我收到错误错误的语法在＆＃39; order＆＃39; 附近。我已将错误隔离到SQLServer 2005（当我在over子句中删除顺序时，错误就消失了）。我查看了文档并搜索了解决方案，但无法找到问题所在。

OVER clause

感谢您的帮助!!

Answer 1

您不能将SUM与OVER和Partition by..Orderby一起使用，仅与PARTITION BY一起使用。订购你想要总结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

如果分区依据与组相同，则应该只能通过

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])
