kfzteile24 / vertica-csv

Command line client for Vertica that outputs valid CSV

Vertica SQL to CSV

Outputs vertica query results as proper CSV.

Uses python's csv library to properly format CSV to one's liking. Outputs the result to stdout, can be piped to any other process.

Tries to mimic the command line arguments of vsql, but had to make some changes to keep it simple and versatile for csv.

Installation

• Clone the repo and change to that directory

git clone https://github.com/kfzteile24/vertica-csv.git
cd vertica-csv

• Initialize the virtual environment (developed and tested on Python 3.7, but should work fine with Python 3.5 as well). Depending on the OS you might have to specify whether it's -p python3 or -p python3.6 or omit it entirely.

python -m vitualenv -p python3 .venv
.venv/bin/pip install -r requirements.txt

Example usage

# Simplest command - execute on localhost with the current user and no password
./vsqlcsv db_name -c "SELECT * FROM public.sales LIMIT 10;"

# Remote connection, with user and password specification
./vsqlcsv --host 192.168.56.20 -U dbadmin -w letmein db_name --header -quoting all -c "SELECT * FROM public.sales LIMIT 10;"

# Piping command and sending output to file
cat query.sql | ./vsqlcsv --host 192.168.56.20 -U dbadmin db_name --header -quoting all > results.csv

You could also copy it to /usr/local/bin/ and thus make it available regardless of pwd.
