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

Run-time error '3085':

Undefined function in expression.



CAUSE
You are using DAO to open a query that contains a user-defined function.



MORE INFORMATION
When using DAO, you can refer to Microsoft Jet objects that are dependent only on other Microsoft Jet objects.

The following steps demonstrate this problem. The steps create a query in Microsoft Access that calls a user-defined function and then tries to open a recordset on that query using DAO in Microsoft Excel.

Steps to Reproduce Behavior
CAUTION: If you follow the steps in this example, you modify the sample database Northwind.mdb. You may want to back up the Northwind.mdb file and follow these steps on a copy of the database.

 Open the sample database Northwind.mdb.  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   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])  Quit Microsoft Access. In Microsoft Excel, create a new workbook.</li>  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 </li> On the Tools menu, click References. Click to select the Microsoft DAO 3.6 Object Library check box, and then click OK.</li> Run the macro called xlTest.

Note that you receive the error message mentioned in the "Symptoms" section of this article.</li></ol>
