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.
