SYMPTOMS

When you perform updates or add new records to an Oracle database by using Microsoft ActiveX Data Objects (ADO), the following error may occur:

ADODB.Recordset (0x800A0CB3)
Object or provider is not capable of performing requested operation.

CAUSE

This error message is generated because the Oracle OLE DB Provider does not support server-side updates.

RESOLUTION

You must use client-side cursors to perform updates against an Oracle database by using the Microsoft Oracle OLE DB Provider. To do this, before opening the recordset, specify the CursorLocation property to equal adUseClient (or the number "3").

STATUS

This behavior is by design.

Steps to Reproduce Behavior

To reproduce this behavior, perform the following steps:

  1. Create a sample table in Oracle with some data by using the following SQL statements:

    CREATE TABLE MYACCT
            (ACCT_NUM   NUMBER  CONSTRAINT pk_Acct_Num PRIMARY KEY ,
             CUST_NUM   NUMBER,
             ACCT_NAME  VARCHAR2(255)) 
    
    INSERT INTO MYACCT VALUES(111,111,'Barry Blue')
                        
  2. Insert the following code into a new Microsoft Active Server Pages (ASP) page:

    <%@ Language=VBScript %>
    <!--METADATA TYPE="TypeLib" NAME="Microsoft Remote Data Services Server 2.5 Library" UUID="{9381D8F6-0288-11D0-9501-00AA00B911A5}" VERSION="1.5"-->
    <!--METADATA TYPE="TypeLib" NAME="Microsoft ActiveX Data Objects 2.5 Library" UUID="{00000205-0000-0010-8000-00AA006D2EA4}" VERSION="2.5"-->
    <%' Replace the above two lines with the following lines to use MDAC 2.6
    '<!--METADATA TYPE="TypeLib" NAME="Microsoft Remote Data Services Server 2.6 Library" UUID="{9381D8F6-0288-11D0-9501-00AA00B911A5}" VERSION="1.5"-->
    '<!--METADATA TYPE="TypeLib" NAME="Microsoft ActiveX Data Objects 2.6 Library" UUID="{00000206-0000-0010-8000-00AA006D2EA4}" VERSION="2.6"-->%>
    <HTML>
    <HEAD>
    <META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0">
    </HEAD>
    
    <BODY>
    <%
        Dim cn, rs
        Set cn = Server.CreateObject("ADODB.Connection")
        Set rs = Server.CreateObject("ADODB.Recordset")
        cn.Open "Provider=MSDAORA.1;Password=tiger;User ID=scott;Data Source=YourDataSource;"
        ' rs.CursorLocation = adUseClient ' Uncomment this line to cause this code to work properly.
        rs.Open "SELECT * FROM MYACCT", cn, adOpenKeyset, adLockOptimistic 
        rs("ACCT_NUM")=333
        rs("CUST_NUM")=333
        rs("ACCT_NAME")="barry white"
        rs.Update 
    
    %>
    
    </BODY>
    </HTML>
                        
  3. Save the page in a folder that is part of a Web application in Internet Information Server (IIS).
  4. Browse to the page using Internet Explorer.
