Actually the reluctance to not use COPY is to make the benchmark same across two different RDBMS in two diff env. --- Seems like a ~10 line Perl program could handle this very easily. Use the Text::CSV module to make handling of the input easier. Prepare your insert statement, then once you've pulled each line of input in execute the insert. For slightly better performance, I'd probably use transactions, add a counter, and commit every 10,000 rows (or something like that). Once you have that working with 1 DB, you can copy your program, change the DBD driver and the connect statement to the other DB and try the other one. Unless you want to be really clever and make the same program do both and pick the DB by a command line switch. :) HTH, Kevin This e-mail transmission, and any documents, files or previous e-mail messages attached to it, may contain confidential information.
