Dear Nick and Barbara,
I am try to using a view now. But i faced some problems.
After i update the view, how to save it back to the original table ?
And if the view records that have been deleted, how to make the original table record also to be deleted ?
Is it i have to overwrite the original table by the updated view ? and how to overwirte a table by another table ?
Thanks.

regards,
kengwen
