Re: JDBC batching

Is there any way to execute batches of stored procedures?

The actual problem is that I want to do a batch of INSERTs, but it is likely
that at least one INSERT will fail - and postgres aborts the entire
transaction. I'd like to push some logic down into a stored procedure, but
maybe I just have to do a batch of DELETEs then a batch of INSERTs.

Thanks,
Tony

Tony,

The batch API works in one round trip in 7.2.

thanks,
