I have several queries in an MS Access database. Some of these use parameters. I use the following code in VBA to provide the query with these parameters:
VB
Simply create a pass-though query in Access and save it.
Ensure that the PT query works. It will likely look like:
Exec MySpName '2017-01-01', '2017-05-31'
Again: 100% Make sure the query works when you click on it in Access. At this point you not written any VBA code.
Once you have above pass through query working, then in VBA you can do this:
Dim strStartDate As String
Dim strEndDate As String
Dim strSQL As String
strStartDate = "'" & Format(Me.dpFrom, "yyyy-mm-dd") & "'"
strEndDate = "'" & Format(Me.dpTo, "yyyy-mm-dd") & "'"
strSQL = "exec MyStoreProc " & strStartDate & "," & strEndDate
With CurrentDb.QueryDefs("QryMyPass")
.SQL = strSQL
Set rst = .OpenRecordset
End With
