使用窗體過濾交叉表查詢MS Access 2010

Question

我正在使用Access 2010.我有一個交叉表查詢，我試圖根據窗體上的文本框的值進行過濾。完整的SQL是如下：

PARAMETERS Forms!SelectForm!Text27 DateTime; 

TRANSFORM nz(Sum([Raw Contract Data].[Action Obligation]), 0) AS [SumOfAction Obligation] 

SELECT [Raw Contract Data].[NAICS Code], [Raw Contract Data].[NAICS Description], Sum([Raw 
Contract Data].[Action Obligation]) AS [Total Of Action Obligation], NZ(round(avg([SumOfAction 
Obligation]),0),) AS [Average Obligation], 
nz(round(stdev([SumOfAction Obligation]),0),0) AS [StDev of CTRs], 
nz(round(var([SumOfAction Obligation]),0),0) AS [Variance of Obligations] 

FROM [Raw Contract Data] 

WHERE [Raw Contract Data].[Date Signed] <= Forms!SelectForm!Text27 

GROUP BY [Raw Contract Data].[NAICS Code], [Raw Contract Data].[NAICS Description] 

PIVOT format([Raw Contract Data].[Date Signed], "yyyy-mm"); 

的問題是，該查詢將運行，但彈出一個框，要求文本27的價值它不會從處於它的價值認識它形成。當我手動輸入一個日期（沒有前面的PARAMETERS聲明）時，WHERE子句將起作用，但是當我希望它引用文本字段的值時，我什麼也得不到。

Answer 1

記住，你必須在打開狀態的形式從你所指的Text27

否則當你執行查詢時，查詢不會因爲形式沒有打開得到的參數值，它會問你價值爲Text27。

Answer 2

給一個嘗試這種方法，讓我知道如果這有助於你

PARAMETERS EnterDate DateTime; 
TRANSFORM nz(Sum([Raw Contract Data].[Action Obligation]), 0) AS [SumOfAction Obligation] 
SELECT [Raw Contract Data].[NAICS Code], [Raw Contract Data].[NAICS Description], 
Sum([RawContract Data].[Action Obligation]) AS [Total Of Action Obligation], 
NZ(round(avg([SumOfAction Obligation]),0),) AS [Average Obligation], 
nz(round(stdev([SumOfAction Obligation]),0),0) AS [StDev of CTRs], 
nz(round(var([SumOfAction Obligation]),0),0) AS [Variance of Obligations] 
FROM [Raw Contract Data] 
WHERE [Raw Contract Data].[Date Signed] <= EnterDate 
GROUP BY [Raw Contract Data].[NAICS Code], [Raw Contract Data].[NAICS Description] 
PIVOT format([Raw Contract Data].[Date Signed], "yyyy-mm"); 

此查詢保存說名字查詢1

在篩選器操作說上點擊過濾器按鈕定義以下代碼

Dim qdf As DAO.QueryDef 
Dim rst as DAO.Recordset 
Set qdf = CurrentDb.QueryDefs("Query1") 
qdf!EnterDate = Forms!SelectForm!Text27 
Set rst = qdf.OpenRecordset 
Set rst = Nothing 
Set qdf = Nothing
