SYMPTOMS

When you use a Microsoft SQL Server stored procedure to request a dynamic recordset with the CursorLocation property set to adUseServer, the recordset is returned with a CursorType of adOpenStatic instead of adOpenDynamic.

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

STATUS

Microsoft is currently reviewing this issue and updates will be added to this article as they become available.

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.
  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=XXX;password=YYY;"
        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, , adOpenDynamic, adLockBatchOptimistic
       
        StrOut = "rs.CursorType = " & rs.CursorType
        Select Case rs.CursorType
            Case 0
                Debug.Print StrOut & " - adOpenForwardOnly"
            Case 1
                Debug.Print StrOut & " - adOpenKeySet"
            Case 2
                Debug.Print StrOut & " - adOpenDynamic"
            Case 3
                Debug.Print StrOut & " - adOpenStatic"
        End Select
    					
  6. Modify the following string to reflect your SQL Server UserID and password:
    oCon.Open "DSN=SQLPUBS;uid=XXX;password=YYY;"
    					
  7. Save and run the project. Notice that the following output appears in the local window:

    rs.CursorType = 3 - adOpenStatic
    							

    instead of:

    rs.CursorType = 2 - adOpenDynamic
