I have a routine in my application where I have the potential to generate hundreds of inserts or deletes at one time. Right now, I issue each insert and delete separately. I'm hoping there might be a way of generating a single SQL statement to send to the backend for each. The deletes look something like
delete from CL where CL_id = i
where i could be a list of several hundred integers. Again, right now I iterate through the list.
The inserts might look like
insert into CL (CO_id, PE_ID) values (j, k)
where j and k are also integers and I could have a list of several hundred pairs of j and k.
MySQL has a multiple insert feature where you simply append a bunch of (j, k)'s separated by a comma. Does PostgreSQL have anything like this? I was hoping I might be able to use COPY, but I see that's really only for psql.
Are there any options? Or, do I simply send a bunch of queries?
Thanks! Mark
