FAQ
Frequently asked questions and answers.
Installation & Launch
Q. I see an "unidentified developer" warning on macOS.
Go to System Settings -> Privacy & Security and click "Open Anyway". Alternatively, run xattr -cr /Applications/NeoSQL.app in the terminal.
Q. I see a SmartScreen warning on Windows.
Click "More info" and then click "Run anyway". NeoSQL is a safe application.
Q. The app doesn't launch or shows a blank screen.
Completely quit the app and relaunch it. If the issue persists, reset the app data or update to the latest version.
Database Connection
Q. The connection test fails.
Check the following: verify the host address and port number are correct, that the database service is running, that the port is open in the firewall, and that the account has remote access permissions.
Q. Can I connect to a localhost DB from the web version?
The web version cannot directly connect to local databases due to browser security policies. Use the desktop app if you need to connect to a local DB.
Q. I want to connect to an unsupported DBMS.
Currently, MariaDB, MySQL, Oracle, PostgreSQL, SQL Server, SQLite, and H2 are supported. Please request additional DBMS support through the Contact Us page.
