Thread: Export Query Output to incremental csv file
Hi guys,
I would like to ask a question about exporting a query output to a csv file but with the particularity that it is incremental (that is, the same file grows in size) since I need to do the query multiple times and I don't want to fill up with csv files... but rather just one that always grows, as if it were a log.
I will add the query to a shell and schedule it using a crontab in Linux Centos.
Thank you very much.
Regards.

COPY ... TO STDOUT, and then append that to the CSV file using ">>".
(Unless I misinterpret what you mean.)

Dear Sir,
This was exactly what I needed, the idea was to do the incremental export in csv... of course I looked for some additional formats like "... stdout with (format csv)" and it worked perfectly.
Thank you very much Ron for your help...
A hug
