SYMPTOMS

If you request a static, server-side cursor from a SQL stored procedure, you cannot use MovePrevious or MoveFirst to move backward through the recordset. The cursor exhibits the behavior of a forward-only cursor.

NOTE: This problem only occurs if there are user-defined variables in the stored procedure or SQL commands such as SET NOCOUNT ON.

After you run MovePrevious or MoveFirst, you receive the following error message:
Run-time error '-2147217884(80040e24)';
Rowset does not support fetching backward.

MORE INFORMATION

Steps to Reproduce Behavior

1.Create a Data Source Name (DSN) named SQLPUBS that points to the SQL Server Pubs database.
2.In the SQL Server Enterprise Manager, modify the ByRoyalty stored procedure. Add SET NOCOUNT ON immediately following the AS portion of the stored procedure, and save the changes.

NOTE: This step is important to reproduce the problem.
3.Create a new Visual Basic Standard EXE project.
4.From the Project menu, click References, and then select the Microsoft Data Access Objects 2.x Library check box.
5.Paste the following code in the form load event:
Dim rs As ADODB.Recordset
    Dim comm As ADODB.Command
    Dim oCon As New ADODB.Connection
    Dim prm As ADODB.Parameter
    Dim StrOut As String
        
    StrOut = ""
    oCon.Open "DSN=SQLPUBS;uid=sa;password=Password1;"
    Set comm = New ADODB.Command
    Set comm.ActiveConnection = oCon
    comm.CommandText = "byroyalty"
    Set prm = comm.CreateParameter("@percentage", adInteger, adParamInput, , 25)
    comm.Parameters.Append prm
    Set rs = New ADODB.Recordset
    
    'rs.CursorLocation = adUseClient
    rs.CursorLocation = adUseServer
      
    rs.Open comm, , adOpenStatic, adLockBatchOptimistic
   'rs.Open "Select * from authors", oCon, adOpenKeyset, adLockBatchOptimistic
       
    Debug.Print "rs.CursorType = " & rs.CursorType
    
    rs.MoveNext
    rs.MovePrevious ' ERROR OCCURS HERE.
