Essentially, I was testing Perl array bind & execute. Everything went well, except for the fact that array execute is no faster than the row-by-row way of executing things. I was surprised because I expected array bind to produce better results over the network than the row-by-row operations, yet it didn't. Can anybody elaborate a bit? It seems that some kind of email scanner has quarantined my emails containing Perl code samples as dangerous, so I can't really show the code sample. -- Mladen Gogala Sr. Oracle DBA 1500 Broadway New York, NY 10036 (212) 329-5251 http://www.vmsinfo.com The Leader in Integrated Media Intelligence Solutions
