queryrunner 0.1.0

Output SQL queries results to file

Query-Runner

CLI tool to help with running queries.

Quickstart

Pass through a sqlalchemy DB URL and a query to run a query and export to file. (You may need the relevant DB drivers installed also.)

python -m queryrunner show "sqlite:///" "SELECT 'Val' as col1"
python -m queryrunner to-csv "sqlite:///" "SELECT 'Val' as col1" "output.csv"

You can also use an environment variable to contain your connection string, and a file to contain your SQL query.

DB_URI="sqlite:///"

# example-query.sql
SELECT 'Val' as col1

python -m queryrunner to-csv "DB_URI" "example-query.sql" "output.csv"

Query Parameters

You can pass query parameters as extra CLI options, but this only works for strings.

So this will work:

python -m queryrunner show "sqlite:///" "SELECT '5' as col1 WHERE col1=:val" --val 5
python -m queryrunner show "sqlite:///" "SELECT 5 as col1 WHERE CAST(col1 as text)=:val" --val 5

But this will not:

python -m queryrunner show "sqlite:///" "SELECT 5 as col1 WHERE col1=:val" --val 5
