Passing recordset parameters from code



I'm trying to use the following code from

Dim lngColumn As Long
Dim xlx As Object, xlw As Object, xls As Object, xlc As Object
Dim dbs As DAO.Database
Dim rst As DAO.Recordset
Dim strPathFileName As String, strWorksheetName As String
Dim strRecordsetDataSource As String
Dim blnEXCEL As Boolean, blnHeaderRow As Boolean

blnEXCEL = False

' Replace C:\Filename.xls with the actual path and filename
' that will be used to save the new EXCEL file into which you
' will write the data
strPathFileName = "C:\Filename.xls"

' Replace QueryOrTableName with the real name of the table or query
' whose data are to be written into the worksheet
strRecordsetDataSource = "QueryOrTableName"

' Replace True with False if you do not want the first row of
' the worksheet to be a header row (the names of the fields
' from the recordset)
blnHeaderRow = True

' Establish an EXCEL application object
On Error Resume Next
Set xlx = GetObject(, "Excel.Application")
If Err.Number <> 0 Then
Set xlx = CreateObject("Excel.Application")
blnEXCEL = True
End If
On Error GoTo 0

' Change True to False if you do not want the workbook to be
' visible when the code is running
xlx.Visible = True

' Create a new EXCEL workbook
Set xlw = xlx.Workbooks.Add

' Rename the first worksheet in the EXCEL file to be the first 31
' characters of the string in the strRecordsetDataSource variable
Set xls = xlw.Worksheets(1)
xls.Name = Trim(Left(strRecordsetDataSource, 31))

' Replace A1 with the cell reference of the first cell into which the
' headers will be written (blnHeaderRow = True), or into which the data
' values will be written (blnHeaderRow = False)
Set xlc = xls.Range("A1")

Set dbs = CurrentDb()

Set rst = dbs.OpenRecordset(strRecordsetDataSource, dbOpenDynaset, dbReadOnly)

If rst.EOF = False And rst.BOF = False Then
' Write the header row to worksheet
If blnHeaderRow = True Then
For lngColumn = 0 To rst.Fields.Count - 1
xlc.Offset(0, lngColumn).Value = rst.Fields(lngColumn).Name
Next lngColumn
Set xlc = xlc.Offset(1,0)
End If

' copy the recordset's data to worksheet
xlc.CopyFromRecordset rst
End If

Set rst = Nothing
Set dbs = Nothing

' Save and close the EXCEL file, and clean up the EXCEL objects
Set xlc = Nothing
Set xls = Nothing
xlw.SaveAs strPathFileName
xlw.Close False
Set xlw = Nothing
If blnEXCEL = True Then xlx.Quit
Set xlx = Nothing

The problem is that the query (Query1) which I use as the recordsource is
based on a parameter query (Query2) taking three parameter values from a
form. That is why I get run-time error 3061 ("Too few parameters: expected
Is it possible to pass those three parameters from the code?

Not directly, no.

What I likely would do in this situation is either

(1) build a dynamic SQL statement to be used for Query1 where the dynamic
SQL statement concatenates the actual parameter values as constants into the
"built" statement, then save that SQL statement as the .SQL property of
Query1; or

(2) use a form that contains controls with values for the parameters, and
have the Query2 read the form to get the parameters (I think this would
work, though I've not tried it); or

(3) open a querydef object based on Query1, resolve the parameters, open a
recordset from the QueryDef object, write the recordset's data into a
temporary table, and then have a query (Query3) read the table for the
records that you currently are trying to get from Query1 in the code.
