DOCUMENT:Q192646 14-SEP-1998 [vbwin] TITLE :PRB: Move 0 Does Not Refresh TimeStamp and Identity Fields PRODUCT :Microsoft Visual Basic for Windows PROD/VER:WINDOWS:5.0,6.0 OPER/SYS:WINDOWS KEYWORDS: ====================================================================== --------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual Basic Enterprise Edition for Windows, versions 5.0, 6.0 --------------------------------------------------------------------- SYMPTOMS ======== With Visual Basic and SQL Server 6.5, Move 0 does not refresh the Timestamp and Identity fields after Update/Addnew, when using the ClientBatch cursor driver. CAUSE ===== A client-side cursor is being used. RESOLUTION ========== Set cursordriver property to rdUseServer. STATUS ====== This behavior is by design. MORE INFORMATION ================ Steps to Reproduce Behavior --------------------------- 1. Create a test table with Timestamp field in SQL Server Pubs database. Run the following code in ISQL/W: CREATE TABLE BankTbl (Account int identity, Balance money, Stamp TimeStamp) INSERT INTO BankTbl (Balance) Values(1000) INSERT INTO BankTbl (Balance) Values(400) INSERT INTO BankTbl (Balance) Values(250) CREATE UNIQUE INDEX AcctIndex ON BankTbl(Account) 2. Create a Standard EXE project in Visual Basic. Form1 is created by default. 3. Add a Reference to Microsoft Remote Data Object 2.0. 4. Place a CommandButton on the form. 5. Add the following code to the General Declarations of the form: Function TSToHex(sBinRep As rdoColumn) As String Dim sBuffer As String Dim b As Integer sBuffer = "0x" For b = 1 To 8 'Break up the binary sBuffer = sBuffer + Right$("00" & _ Hex(AscB(MidB(sBinRep, b, 1))), 2) Next b TSToHex = sBuffer 'Return the string End Function Private Sub Command1_Click() Dim cn As New rdoConnection Dim rs As rdoResultset Dim Timestamp As Variant Dim strConnect As String Dim strSQL As String strConnect = "Driver={SQL Server};Server=servername;Database= _ pubs;Uid=sa;Pwd=" With cn .CursorDriver = rdUseClientBatch .Connect = strConnect .EstablishConnection End With strSQL = "Select Account, Balance, Stamp from BankTbl" Set rs = cn.OpenResultset(strSQL, rdOpenstatic, rdConcurBatch) Debug.Print TSToHex(rs("Stamp")) rs.Edit rs!Balance = 99 rs.BatchUpdate rs.Move 0 Debug.Print TSToHex(rs("Stamp")) End Sub 6. Press the F5 key to execute code and note the same value appears twice in the Immediate Window.
