VBA: Run-Time Error 3085 Using DAO

• Microsoft Visual Basic for Applications version 5.0
• Microsoft Access versions 7.0, 97

SYMPTOMS

When you use Data Access Objects (DAO) in a Microsoft Office program to open a Microsoft Access query, you receive the following error message:

Run-time error '3085':
Undefined function <function name> in expression.

CAUSE

You are using DAO to open a query in Microsoft Access that contains a user- defined function.

MORE INFORMATION

You can only refer to Microsoft Jet objects that are only dependent on other Microsoft Jet objects when using DAO in other Microsoft Office programs. The following steps demonstrate this problem by creating a query in Microsoft Access that calls a user-defined function and then attempting to open a recordset on that query using DAO in Microsoft Excel.

Steps to Reproduce Behavior

1. Open the sample database Northwind.mdb in Microsoft Access.



2. Create a module and type the following procedure:




      Function IsInternational(strCountry As String) As String
         If strCountry = "USA" Then
            IsInternational = "Local"
         Else
            IsInternational = "Intl"
         End If
      End Function 

3. Create a new query based on the Customers table as follows:




      Query: qryExcelTest
      --------------------------------------
      Type: Select Query

      Field: CompanyName
         Table: Customers
      Field: Country
         Table: Customers
      Field: Expr1: IsInternational([Country]) 

4. Quit Microsoft Access.



5. In Microsoft Excel, create a new workbook.



6. On the Tools menu, point to Macros, and then click Visual Basic Editor. In the Visual Basic Editor, insert a new module sheet by clicking Module on the Insert menu. Type the following sample macro (Sub procedure).




      Sub xlTest()
         Dim db As Database, rs1 As Recordset
         Dim qry As QueryDef
         Set db = Workspaces(0).OpenDatabase _
         ("C:\Program Files\Microsoft Office\Office\Samples\Northwind.mdb")
            ' Replace the above path with the correct path to the
            ' sample Northwind.mdb database on your computer.
         Set qry = db.QueryDefs("qryExcelTest")
         Set rs1 = qry.OpenRecordset
         rs1.MoveLast
         rs1.Close
         db.Close
      End Sub 

7. On the Tools menu, click References. Click to select the "Microsoft DAO 3.5 Object Library" check box, and then click OK.



8. Run the macro titled "xlTest." Note that you receive the error message noted in the "Symptoms" section of this article.
