Time to complete: 10 minutes
Step 1: Download SQL Developer
Download SQL Developer from our website. Unlike Oracle's official site, you don't need to create an account or log in.
- Go to getsqldeveloper.com/download
- Click Download Free for Windows
- Save the .zip file to your Downloads folder
The download is approximately 450MB and includes a bundled JDK, so you don't need Java installed separately.

Step 2: Extract the ZIP File
SQL Developer is a portable application. After you download SQL Developer, simply extract and run — no installation wizard required.
- Locate the downloaded
sqldeveloper-24.3.1.xxx-x64.zipfile - Right-click and select Extract All...
- Choose a destination folder (e.g.,
C:\sqldeveloper) - Click Extract
Tip: Avoid extracting to Program Files to prevent permission issues. A simple path like C:\sqldeveloper works best.
Step 3: Launch SQL Developer
After extraction, you can run SQL Developer immediately. No additional setup is needed.
- Open the extracted folder (e.g.,
C:\sqldeveloper) - Navigate to the
sqldevelopersubfolder - Double-click
sqldeveloper.exe
First launch: SQL Developer may take 30-60 seconds to start the first time as it initializes settings. Subsequent launches will be faster.
Windows SmartScreen: If you see a "Windows protected your PC" message, click More info then Run anyway. This is normal for downloaded applications.
Step 4: Create Your First Connection
Now that you've downloaded SQL Developer and launched it, let's connect to a database. SQL Developer supports Oracle, MySQL, PostgreSQL, SQL Server, and SQLite.
- Click the green + icon in the Connections panel (left side)
- Enter a Connection Name (e.g., "My MySQL Database")
- Select the Database Type tab (MySQL, PostgreSQL, etc.)
- Enter your connection details:
- Hostname: Your database server address
- Port: MySQL: 3306, PostgreSQL: 5432, Oracle: 1521, SQL Server: 1433
- Username: Your database username
- Password: Your database password
Step 5: Test and Connect
Before saving your connection, always test it to verify your credentials are correct.
- Click the Test button at the bottom of the connection dialog
- If successful, you'll see "Status: Success" in green
- Click Save to save the connection for future use
- Click Connect to open the connection
Connection failed? Common issues:
- Connection refused: Check that your database server is running and the port is correct
- Access denied: Verify your username and password
- Timeout: Check your firewall settings or try connecting via SSH tunnel
