Re: JDBC batching

Yeah, I've submitted a patch and according to Barry, it was already
fixed. If not, I can re-submit the patch.

It does not appear to be so. I grabbed 7.2rc2, and the JDBC driver
shipped
with it still implements a batch update with multiple round trips. I
verified this both by sniffing the network packets, reading the shipped
code, and disassembling the Statement class that I'm running. I even
checked
the CVS repository at jdbc.postgresql.org.

Am I missing something here?

Thanks,
Tony

Tony,

The batch API works in one round trip in 7.2.

thanks,
