MS Access ===> ORACLE

I installed Oracle8.1.6 client and ODBC on my pc.
Now I can connect to the Oracle database 8.1.6 and set up the linked table in MS access database. How could I update the Oracle database table from the linked table in MS access database?

For example, there is a table name test_odbc in ORACLE DB.
I setup a linked table link_test_odbc in the MS access DB.
What I want to do is to update the table link_test_odbc from MS access, then test_odbc in ORACLE DB is updated.
But when I tried to update table link_test_odbc in MS access I got the message " the recordset is not updateable".

Any idea? Thanks.

There are some Notes in Metalink but they mention ADO or Visual Basic, and the solution are:
1.-set the 'Updateability' property to updateable
2.-cmd.Properties("IRowsetChange") = TRUE
3.-Rst.open "select ename,empno,job from scott.emp",con,adOpenStatic,adLockOptimistic,adcmdText

But my first thought was on a property on the ODBC DSN itself, maybe a Read-only checkbox
Hope it helps.

Thanks, Rcaballe. I solved the problem according to your idea.
