ACC97: IPF in Msjet35.dll Running Update Against Attached Table

• Microsoft Access 97

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

When you use a user-defined function in the Update To row of an update query based on an attached SQL Server table, you may receive the following error message:

MSACCESS caused an invalid page fault in module MSJet35.DLL at 0137:040df209

RESOLUTION

There are two methods you can use to resolve this problem. In the first method, you create a make-table query with a user-defined function to create a temporary table. You then create an update query based on the temporary table and the SQL server table. In the second method, you perform the update manually in code.

NOTE: Both methods assume you have an attachment to the Sales table in the PUBS sample database within Microsoft SQL Server and a function called Test(). To create the Test() function, follow these steps:

1. Create a module and type the following line in the Declarations section if the line is not already there:




Option Explicit 

2. Type the following procedure:




Function Test(qtyVal As Integer) As Integer
   Test = qtyVal + 10
End Function 

3. Close and save the module as modTest.

Method 1

1. Create the following query based on the dbo_Sales table:




   Query: qryTemp
   -------------------------
   Type: Select
   Field: Stor_id
   Field: Ord_Num
   Field: Title_id
   Field: Expr1: Test([qty]) 

2. On the Query menu, click Make-Table, and then in the Table Name box, type tblTemp. Click OK.



3. Save the query as qryTemp.



4. Run the qryTemp query and close it.



5. Create the following update query based on dbo_Sales and tbltemp tables:




   Query: qryUpdate
   -------------------------------------------------
   Type: Update
   Join: tblTemp.[Stor_id] <-> dbo_Sales.[Stor_id]
   Join: tblTemp.[Ord_num] <-> dbo_Sales.[Ord_num]
   Join: tblTemp.[Title_id] <-> dbo_Sales.[Title_id]
   Field: [qty]
      Table: dbo_Sales
      Update To: [tblTemp].[Expr1] 

6. Save the query as qryUpdate



7. Run the query to update the qty field in the Sales SQL attached table.

Method 2

1. Create a module and type the following line in the Declarations section if the line is not already there:




Option Explicit 

2. Type the following procedure:




Function UpdateId()
   Dim MyDb as Database
   Dim MyRS as RecordSet
   Dim MyVar as Long
   Set MyDb = CurrentDB()
   Set MyRS = MyDB.OpenRecordset("dbo_sales",dbOpenDynaset)
   MyRS.MoveFirst
   Do While Not MyRS.EOF
      MyVar = Test([MyRS![qty])
      MyRS.Edit
      MyRS![qty] = MyVar
      MyRS.Update
   Loop
   MyRS.Close
End Function 

3. Close and save this module as modUpdateSQL



4. To test this function, type the following line in the Debug window, and then press ENTER:




?UpdateID()

STATUS

Microsoft has confirmed this to be a problem in Microsoft Access 97. This problem no longer occurs in Microsoft Access 2000

MORE INFORMATION

Steps to Reproduce Problem

1. Create a new database, and then on the File Menu, point to Get External Data, and click Link Tables.



2. From the Files Of Type list, click ODBC Databases(), select the SQL Server Data Source, and then click OK.



3. Click Options and type Pubs in the Database box, and click OK.



4. Select the Sales table from the list, and then click OK.



5. Create a module and type the following line in the Declarations section if the line is not already there:




Option Explicit 

6. Type the following procedure:




Function Test(MyVar as Long) as Long
   Test = MyVar /1
End Function 

7. Close and save the module as Module1.



8. Create the following query based on the dbo_Sales table:




   Query: qryTest
   --------------------
   Type: Update
   Field: [qty]
   Update To: Test(qty) 

9. Close and save this query as qryTest.
   
   Note that when you run the qryTest update query, you receive the error message mentioned in the "Symptoms" section.
