VBA adding to array at runtime

I am trying to create an int array at runtime from results of a record set.

Do While Not rstSearchResult.EOF

 If rstSearchResult(ID) = blah Then 
  'Add this Id rstSearchResult(ID) to Array
 End If

 Call rstSearchResult.MoveNext()
Loop

What I need is 开发者_运维问答that same result as this will give me Array(35588, 35589, 35595)

Dim myIntArray() as Integer
Dim intDimension as Integer

intDimension = 0

Do While Not rstSearchResult.EOF

 If rstSearchResult(ID) = blah Then   
  'Add this Id rstSearchResult(ID) to Array
  REDIM PRESERVE myIntArray(intDimension)
  myIntArray(intDimension) = rstSearchResult(ID)
  intDimension = intDimension +1
 End If

 Call rstSearchResult.MoveNext()
Loop

When I need to copy from a Recordset to an array, it's a little bit more efficient to ReDim the array to the size you want beforehand instead of ReDiming it inside the loop.

Dim myIntArray() as Integer
Dim intDimension as Integer

rstSearchResult.Filter = "ID = " & blah
ReDim myIntArray(rstSearchResult.RecordCount - 1)

intDimension = 0
Do Until rstSearchResult.EOF
    myIntArray(intDimension) = rstSearchResult!ID
    intDimension = intDimension + 1
    rstSearchResult.MoveNext
Loop

Note that for RecordCount to work you need to open the recordset as static.

rstSearchResult.Open "tblSearchResult", cnn, adOpenStatic

When I do VBA in excel I have a class I use for the DB accessing in it I have a function that returns the recordset to an array. Hope the below helps.

Public Function RSToArray(ByVal oRS, Optional ByVal iRows, Optional ByVal iStart, Optional ByVal aFieldsArray)
    If iRows = 0 Then iRows = adGetRowsRest
    If iStart = 0 Then iStart = adBookmarkfirst

    RSToArray = ""  ' return a string so user can check For (IsArray)

    If IsObject(oRS) And oRS.State = adStateOpen Then
        If Not oRS.BOF And Not oRS.EOF Then
            If IsArray(aFieldsArray) Then
                RSToArray = oRS.GetRows(iRows, iStart, aFieldsArray)
            Else
                If iRows <> adGetRowsRest Or iStart <> adBookmarkfirst Then
                    RSToArray = oRS.GetRows(iRows, iStart)
                Else
                    RSToArray = oRS.GetRows()
                End If
            End If
        End If
    End If
End Function
