Обсуждение: using COPY and PARTITON
hi~ I want to insert DATA by using the COPY making PARTITON TABLE. By the way, DATA is inserted only in PARENT TABLE. Can DATA be inserted in CHILD TABLE by using the COPY?

I believe triggers can do it. On Sun, Aug 9, 2009 at 11:15 PM, cjm1010<cjm1010@naver.com> wrote: > > hi~ > > I want to insert DATA by using the COPY making PARTITON TABLE. By the way, > DATA is inserted only in PARENT TABLE. > Can DATA be inserted in CHILD TABLE by using the COPY?
Hi, I'd recommend coping directly to child tables (partitions). It's much faster.

thanks for reply I am using rules with libpq instead of triggers now. When INSERT was used, it was possible to insert it in CHILD TABLE well. However, if COPY is used, it is possible to insert it only in PARENT TABLE. Can triggers be used with libpq? And, if trigger is used, can it straighten out that problem?

Yep, triggers work just fine with libpq (if they didn't FK constraints wouldn't work). I switched from rules to triggers a while back for my reporting / stats database and they work a charm.
