sqlline

A command‑line shell enables execution of SQL statements against any relational database that provides a JDBC driver. Users launch the tool, supply a driver class or JDBC URL, and then interactively issue queries, list tables, and retrieve results directly in the terminal. The shell supports common commands such as `!connect`, `!tables`, and `!quit`, and can be invoked via a provided script, a Windows batch file, or by running the bundled JAR with Java.

The project is a modernized, Maven‑hosted fork of an earlier sqlline implementation, incorporating updates from the LucidDB effort. It is released under a 3‑clause BSD license, allowing unrestricted redistribution and modification. Pre‑built JARs with dependencies are available on Maven Central, and the source can be built with Java 8 or newer using the included Maven wrapper.

Developers and database administrators who need a lightweight, scriptable interface for ad‑hoc querying, testing, or automation across diverse JDBC‑compatible systems can integrate sqlline into scripts, CI pipelines, or use it interactively for quick data inspection.
