Hi all.
I am using Visual FoxPro via ODBC to update records on a 7.3.4
PostgreSql server and it appears that it always uses delete/insert
instead of updating the current record. Can this be changed to update
the existing record instead?

Depneding on why you want to do this, it might not help. Postgres
uses MVCC and updates are effectively inserts and deletes.

I'm not sure if you are saying that Foxpro is doing a delete / insert, or
that postgresql is doing one.
Every update in postgresql is, in fact, a delete / insert, with the delete
delayed until no more transactions are looking at that version of the row
and vacuum has been run.
So, if Visual Foxpro is in fact issuing a delete insert, it's likely no
great performance hit for postgresql, which would wind up doing the same
basic thing anyway.

Hi,
If I am updating a list of records for a user on an asp page, is there
a way to hold the page updating, even if they refresh the page, until I
have updated all the records.
i.e. rather than them seeing records change 1 at a time if they
refreshed their page, all the records would update together in 1 go, a
bit like a batch update ?

existing records, whichever was relevant. This may also include deleting
records.
Now I generally do this by opening a recordset on the source data...
