Microsoft Access从SQL数据库查询选择Count Distinct Issue

Question

我有一个问题：

SELECT COUNT(DISTINCT dbo_tblBidder.bidder_id) AS TotalRegistrants, 
    SUM(dbo_tblItem.item_premium + dbo_tblItem.item_pr) AS SumTotal, 
    dbo_tblBidder.bidder_type

FROM dbo_tblBidder LEFT OUTER JOIN dbo_tblItem ON 
    dbo_tblItem.item_bidder_number = dbo_tblBidder.bidder_number AND 
    dbo_tblItem.item_sale_id = dbo_tblBidder.bidder_sale_id

WHERE (dbo_tblBidder.bidder_sale_id = 235)

GROUP BY dbo_tblBidder.bidder_type

当我尝试在MS Access中执行此操作时，我被告知：

Missing oporator 'COUNT(DISTINCT dbo_tblBidder.bidder_id)'

当我点击＆＃34;确定＆＃34;时，它会突出显示＆＃34; dbo_tblBidder＆＃34;。这个查询在SQL服务器上运行得很好，我不知道MS Access认为缺少哪个oporator。任何帮助将不胜感激。

更新

我实际上必须尝试：

SELECT     Total.count, SUM(dbo_tblItem.item_premium + dbo_tblItem.item_pr) AS SumTotal, dbo_tblBidder.bidder_type
FROM         dbo_tblBidder LEFT OUTER JOIN
                  dbo_tblItem ON dbo_tblItem.item_bidder_number = dbo_tblBidder.bidder_number   AND 
                  dbo_tblItem.item_sale_id = dbo_tblBidder.bidder_sale_id LEFT OUTER JOIN
                      (SELECT     COUNT(bidder_type) AS count, bidder_type
                        FROM          dbo_tblBidder AS tblBidder_1
                        WHERE      (bidder_sale_id = 235)
                        GROUP BY bidder_type) AS Total ON dbo_tblBidder.bidder_type = Total.bidder_type
WHERE     (dbo_tblBidder.bidder_sale_id = 235)
GROUP BY dbo_tblBidder.bidder_type, Total.count
ORDER BY dbo_tblBidder.bidder_type

我正在等待那个试图运行它的人的回复，看看这对他们是否有效。

更新

这不起作用。现在，它告诉我：

  

查询表达式中的语法错误（缺少运算符）＆＃34;。

然后，它突出了＆＃34; mber＆＃34;来自dbo_tblBidder.bidder_number，其中说：

  

dbo_tblItem ON dbo_tblItem.item_bidder_number = dbo_tblBidder.bidder_number

Answer 1

Access不支持COUNT Distinct。如果您需要，可以试试here。

Answer 2

聚合函数（Count函数）中有Distinct。删除distinct，它应该可以正常工作。

如果您仍然需要计算不同的bidder_ID，我建议您在单独的查询中提取。
