Your best bet would be OCI in general (not sure if the stored proc would be
the most effecient). But using OCI and host variables and array inserts
would be very fast. Minimizes the round trips and minimizes the parsing.
ODBC supports string substitution for host variables instead of host
variables and so OCI should be much faster. Host variables are important to
minimize the reparsing (CPU load on the server). They would speed things up
signifigantly.
