I don't know much about the inner woorkings of ADO, but to me it would not be first choice in dealing with large volumes of data. There is a lot of overhead in ADO and the multiple hoops and calls that are needed to make it work.

[Quoted] I'd rather use something more direct. You should be able to pass arrays to PL/SQL and have the procedure do an insert loop or even an array insert via dynamic sql. That will definitely be fatser than multiple calls to the overhead of ADO.

BTW, I've reduced the X-posting.
