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.
Back to the top
This error message is generated because the Oracle OLE DB Provider does not support server-side updates.
Back to the top
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").
Back to the top
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"-->%>

rs.Open "SELECT * FROM MYACCT", cn, adOpenKeyset, adLockOptimistic
rs("ACCT_NUM")=333
