Sqldef is a command-line interface (CLI) tool designed for comparing two SQL schemas. It facilitates the management of database migrations by generating the necessary SQL Data Definition Language (DDL) statements. This tool is particularly useful for developers and database administrators who need to ensure that their database schemas are aligned during updates or migrations.
Supported databases include popular options like MySQL, MariaDB, TiDB, PostgreSQL, SQL Server, and SQLite3. Sqldef allows users to perform diffs in two directions: from the current schema to the desired schema (Up), or from the desired schema back to the current one (Down). This flexibility helps teams to track changes effectively and maintain consistency across different database environments.
An online demo is available that utilizes a WebAssembly version of sqldef. This demo allows users to test the tool's capabilities by diffing SQL schemas directly in their browser. The hands-on experience can help users understand how sqldef generates DDLs and how it can fit into their workflow for managing database changes.
