Use SQL Developer

什麼是 Use SQL Developer？

SQL Developer is Oracle's free database IDE for Windows. It connects to Oracle, MySQL, PostgreSQL, SQL Server, and SQLite from a single interface. The problem: Oracle's official download page requires creating an account, verifying your email, and logging in just to get a free tool. We host a direct download mirror — same file from Oracle's CDN, zero friction. No account, no login, no registration.
