Problem in update , insert with Joined Query DataSet

We are using, delphi 50 with update pack 1 and ADO with mdac 2.6 and
MS SQL Server 7 platform.

In BDE there is no problem to update or insert in Joined Query logic, it is
using Updatequery component but we could 'nt  do these things in ADO.
Would you give us a simple code which can do update , insert with Joined
Query DataSet?
