訪問2007年：從幾個表計數的查詢

大概十年來我還沒有使用過Access，所以我很抱歉如果這是簡單的下降。我有三張桌子。表1-用戶信息表2-報告信息表3-修正信息。訪問2007年：從幾個表計數的查詢

表2和表3通過表1鏈接在一起（表2使用表1的ID，表3使用表1的縮寫名稱）。

我需要有一個查詢按日期計算每個用戶的所有報表，並且還按用戶按日期統計更正信息。

示例查詢：

-user- |日期 - | - 表1計數 - | - 表2計數 -

用戶1 | 08/01/2012 | 33個報道| 2更正

用戶2 | 08/01/2012 | 4個報告| 0更正

用戶1 | 08/02/2012 | 0報告| 1更正

（零的意思是沒有找到記錄，但在另一個表中找到了該日期的記錄）。

以下是我到目前爲止對於SQL所具有的功能。

SELECT 
    tblUsers.userfullname, Count(txtReports.reportnumber) AS CountOfreportnumber, 
    Count(tblRawData.reportnum) AS CountOfRawReport 
FROM (tblUsers INNER JOIN txtReports ON tblUsers.userID = txtReports.userID) 
    INNER JOIN tblRawData ON tblUsers.userabbrev = tblRawData.username 
GROUP BY tblUsers.userfullname;

但是，它給了我的只是部分匹配，每列都有相同的總數。

任何指針？

請提供樣本數據和期望的輸出。 – RedFilter

根據要求添加數據 – Chasester

你需要得到的計數爲每個表，然後加入他們的行列，並顯示它們，否則你會得到一個聚集混亂，沒有你的計數將是正確的。

SELECT u.userfullname, nz(rd.rawcount,0) AS rawcount, nz(rp.rptcount,0) AS rptcount 
FROM (tblUser AS u 
    LEFT JOIN (SELECT username, count(reportnum) AS rawcount FROM tblRawData GROUP BY username) AS rd 
    ON u.userabbrev = rd.username) 
    LEFT JOIN (SELECT userID, count(reportnumber) AS rptcount FROM txtReports GROUP BY userID) AS rp 
    ON u.userID = rp.userID 
WHERE (Not p.Payments Is Null) OR (Not n.Notes Is Null);

謝謝，當我運行它時，我收到一個錯誤「你試圖執行一個查詢，不包含用戶名作爲聚合函數的一部分」我是否需要一個組？ – Chasester

該死的剪切和粘貼我錯過了，當我將它轉換爲你的命名約定。讓我糾正一下。 – Omnikrys

也改變了加入方法並添加了一個WHERE子句，所以它完全符合你的要求。當我試圖走出門外時，我真的不應該這樣做。對不起，先前的嘗試。：p – Omnikrys

嘗試：

SELECT tblUsers.userfullname, tr.CountReport, td.CountRaw 
FROM (tblUsers 
LEFT JOIN (
    SELECT r.userID, Count(r.reportnumber) AS CountReport 
    FROM txtReports r 
    GROUP BY r.userID) AS tr 
ON tblUsers.userID = tr.userID) 
LEFT JOIN (
    SELECT tblRawData.username, Count(tblRawData.reportnum) AS CountRaw 
    FROM tblRawData 
    GROUP BY tblRawData.username) AS td 
ON tblUsers.userabbrev = td.username

謝謝，不幸的是，它添加它們真的很奇怪。 – Chasester

在這種情況下，您應該發佈樣本數據。 – Fionnuala

按要求添加數據 – Chasester
