Thanks, Sam and Martijn. I am attempting to use the COPY command now. I had misunderstood what was meant by STDIN and assumed I could only use a file for my application and wasn't aware of PQputCopyData(). One assumption I am operating under right now is that the format of the binary file is the same as the buffer in PQputCopyData, including the header. If I am wrong, could someone please let me know?

Just to expand on what Martin said; if you can generate a set of EXECUTE commands, you can certainly generate a COPY command to insert the same data. The advantage is a large drop in parse time for inserting larger numbers of rows. As you're saying you want to insert 500 rows, I'd suggest at least trying to get COPY working. -- Sam http://samason.me.uk/ -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general This electronic mail message is intended exclusively for the individual(s) or entity to which it is addressed.
