【问题描述】：

我正在使用 Access 2010。我有一个交叉表查询，我试图根据表单上文本框的值进行过滤。完整的SQL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");

问题是查询会运行，但会弹出一个框，询问文本 27 的值。它无法从表单中的值识别它。当我手动输入日期（没有前面的 PARAMETERS 声明）时，WHERE 子句将起作用，但是当我希望它引用文本字段的值时，我什么也得不到。

【解决方案1】：

试试这个方法，如果对你有帮助，请告诉我

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");

保存这个查询说名字Query1

On Filter action say on clicking filter button定义如下代码

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

【讨论】：

可以用宏代替vba吗？

【解决方案2】：

请记住，您引用 Text27

的表单必须处于打开状态

否则当你执行查询时，由于表单没有打开，查询没有得到参数值，它会询问你Text27的值。

【讨论】：

是的。我有它处于打开状态。
