【问题描述】:
我的程序的一般解释:
- 我在表单上为用户输入做参考控制。 (开始日期前) 2017 年 8 月 1 日和 2017 年 8 月 31 日之前的结束日期)
- 然后我的查询基于参数运行并返回单个值:ex) 12345.23
- 运行 VBA 函数。
问题:querydef 对先前打开的查询一无所知。因此,我想在 VBA 中提供参数,但从这一点上我一无所知:
Set qry = CurrentDb.QueryDefs("2_Total")
Set rst = qry.OpenRecordset
For Each prm In qry.Parameters
prm.Value = Eval(prm.Value)
Next
我的 SQL 代码:
SELECT Sum(dbo_SO_SalesHistory.DollarsSold) AS SumOfDollarsSold
FROM dbo_SO_SalesHistory
HAVING (((dbo_SO_SalesHistory.InvoiceDate) Between [Forms]![RUN]![textBeginOrderDate] And [Forms]![RUN]![textendorderdate]));
这里是完整的代码:
Option Compare Database
Option Explicit
Public Function TRANS2()
Dim xlApp As Excel.Application
Dim xlWB As Excel.Workbook
Dim xlWS As Excel.Worksheet
Dim acRng As Variant
Dim xlRow As Integer
Dim qry As QueryDef
Dim rst As Recordset
Dim prm As DAO.Parameter
Set xlApp = New Excel.Application
Set xlWB = xlApp.Workbooks.Open("C:\Users\J\Desktop\August 2017.xlsx")
Set xlWS = xlWB.Worksheets("Totals")
xlRow = (xlWS.Columns("K").End(xlDown).Row)
Set qry = CurrentDb.QueryDefs("2_Total")
Set rst = qry.OpenRecordset
For Each prm In qry.Parameters
prm.Value = Eval(prm.Value)
Next
Dim c As Integer
c = 11 'C is the one that stores column number, in which c=1 means column A, 11 is for column K, 12 for Column L
xlRow = xlRow + 11
Do Until rst.EOF
For Each acRng In rst.Fields
xlWS.Cells(xlRow, c).Formula = acRng
c = c + 1
Next acRng
xlRow = xlRow + 1
c = 1
rst.MoveNext
If xlRow > 25 Then GoTo rq_Exit
Loop
rq_Exit:
rst.Close
Set rst = Nothing
Set xlWS = Nothing
xlWB.Close acSaveYes
Set xlWB = Nothing
xlApp.Quit
Set xlApp = Nothing
Exit Function
End Function
附言我可以将单元格设置为 DSum() 返回的值,但我想按照我的方式进行操作。 我的好参考是https://msdn.microsoft.com/en-us/library/office/ff193967.aspx。
编辑:
Set qry = CurrentDb.QueryDefs("2_Total")
For Each prm In qry.Parameters
prm.Value = Eval(prm.Value)
Next
Set rst = qry.OpenRecordset
我在 For Each 之后移动了 Set rst = qry.OpenRecordset,现在我得到了
您输入的表达式包含无效语法。
在线prm.Value = Eval(prm.Value)
对此的任何建议将不胜感激。
