Обсуждение: Exporting postgres query to CSV
Greetings, I am running postgres 7.4.7 on debian sarge. I need to run an SQL query and store the results in a file. The format needs to be comma separated values (CSV), so I can import this later in Excel. Any ideas on how to accomplish this? much appreciated, Ryan

First: psql -U <PGSQL USER> -o <OUPUT FILE NAME> --pset format=unaligned --pset fieldsep=',' -c '<SQL COMMAND HERE>' -d <DATABASE NAME HERE> I think that will give you the output you were after assuming you're scripting psql and that you replace the values in <> with appropriate values. The syntax is slightly different from the psql command line. Second: man psql is your friend. John Purser
A word of advice: if there is any chance that a column (e.g. text) contains an embedded newline, you will be much better off outputting the data in simple xml, instead of CSV. This works very well with Excel for import. I just did a simple program for this recently. Susan Ryan Suarez <ryan.suarez@sheridanc.

If the csv generator correctly quotes values containing quotes, commas and newlines, Excel is going to be happy with the csv file as well /Nis

If you need to stick with 7.4 you should at least be running the most current version. -- Jim C.
