Re: create a script which imports csv data

Hi,

I have to create a script which imports csv data into postgresql ...and have a few questions about the best way to do it.

The advice already given is pretty good. Remember you can always create a clean new table then INSERT INTO ... SELECT to populate it from a scratch table you loaded your CSV into, so you don't have to do your cleanups/transformations to the CSV or during the COPY its self.

If it's a big job, it's going to be regular, you're going to have to merge it with more imports later, etc, consider an ETL tool like Penatho. http://kettle.pentaho.com/

For very very fast loading of bulk data, consider pg_bulkload http://pgbulkload.projects.postgresql.org/ . It's only worth the hassle if your load will take many, many hours without it.
