To manipulate LONG RAW types effectively, you need to resort to the OCI - this allows chunk by chunk manipulation of data. (I don't the manual handy - take a peek)

If you just want to deal with the 1MB blob all at once from within PRO*C, you need to perform a datatype equivilence with VARRAW. See the manual for an example of this.

Hope this helps,

Simon.
