USE AT YOUR OWN RISK

query-csv is a simple tool that uses a CSV to populate SQL query parameters.

Getting Started

Requirements

• Go

Installing

Usage

Make sure that your connection string and query follow the requirements for the chosen database driver. For example, with the PostgreSQL driver, the connection string and query parameters should follow that outlined in the Supported Database Drivers section.
