ACC1x: GetChunk on ODBC Table Returns "Invalid Argument"

• Microsoft Access versions 1.0, 1.1

SYMPTOMS

When you call the GetChunk method against a SQL Server or other ODBC table, Microsoft Access returns the error message: "Invalid Argument."

CAUSE

Microsoft Access does not properly support the GetChunk method against ODBC tables.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Access versions 1.0 and 1.1. This problem no longer occurs in Microsoft Access version 2.0.

MORE INFORMATION

Steps to Reproduce Problem

1. Create a SQL Server table called SQLTest with a field called FldImage that has an image data type. Create a unique index on the table.



2. Start Microsoft Access and open the sample database NWIND.MDB.



3. Attach the SQLTest SQL Server table. The table name will be displayed as dbo.SQLTest, and will change to dbo_SQLTest after you attach it.



4. From Microsoft Access, add one record to the table.



5. Create a new module and enter the following sample code:
   

   
         Sub TestGetChunk()
            Dim MyDB As Database, MyDyna As Dynaset, s As String
   
            Set MyDB = CurrentDB()
            Set MyDyna = MyDB.CreateDynaset("dbo_SQLTest")
            s = MyDyna![FldImage].GetChunk(0, 10)
            MyDyna.Close
            MyDB.Close
         End Sub 




6. Type the following in the module's Immediate window:
   
   TestGetChunk
