Access VBA - OrderBy with multiple field - sql

Question

I wonder how I should do this. Actually, I have some subform and, by clicking on the title, I want the recordset of this subform to orderby. This is an example of what I do:
Private Sub sigle_cours_Label_Click()
If (Me.OrderBy = "COU.sigle_cours") Then
Me.OrderBy = "COU.sigle_cours DESC"
Else
Me.OrderBy = "COU.sigle_cours"
End If
Me.OrderByOn = True
End Sub
My problem is this one : I want to OrderBy with sigle_cours AND num_cours but it don't work. I try this but there's no way to sort by DESC :
Private Sub sigle_cours_Label_Click()
If (Me.OrderBy = "COU.sigle_cours,COU.num_cours") Then
Me.OrderBy = "COU.sigle_cours DESC,COU.num_cours DESC"
Else
Me.OrderBy = "COU.sigle_cours,COU.num_cours"
End If
Me.OrderByOn = True
End Sub
How should I do this?

Answer 1

When you assign a string value to the OrderBy property, Access may transform it ... so won't exactly store what you expect. In your case, I suspect Access adds a space after the comma, so if you include this in your Form's code ...
Me.OrderBy = "COU.sigle_cours,COU.num_cours"
Debug.Print "Me.OrderBy='" & Me.OrderBy & "'"
You might see this in the Immediate Window ...
Me.OrderBy = 'COU.sigle_cours, COU.num_cours'
Actually I'm not positive that is the explanation for your problem. Nevertheless I suspect you're more likely to find joy by pattern-matching the current OrderBy value instead of testing for an exact match to a fixed string. Try it this way:
Private Sub sigle_cours_Label_Click()
If (Me.OrderBy Like "*DESC*") Then
Me.OrderBy = "COU.sigle_cours, COU.num_cours"
Else
Me.OrderBy = "COU.sigle_cours DESC, COU.num_cours DESC"
End If
Me.OrderByOn = True
End Sub
