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 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
CAUTION: Following the steps in this example will modify the sample database Northwind.mdb. You may want to back up the Northwind.mdb file and perform these steps on a copy of the database.  Open the sample database Northwind.mdb in Microsoft Access.  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 3.5 Object Library" check box, and then click OK.</li> Run the macro titled "xlTest." Note that you receive the error message noted in the "Symptoms" section of this article.</li></ol>
