Connect with Any MySQL Compatible Tool to SingleStore Helios

In general, if the client you are using to connect supports the MySQL protocol, you can use it to connect to SingleStore Helios. For example, if you connect Wordpress to MySQL, you can probably use most of the same configuration to connect to SingleStore Helios.

This guide should help you troubleshoot any issues that come up. The main thing is to make sure you're using the correct connection details.


When using a third-party SQL client or development tool, you must first add a database user to log into a SingleStore Helios database.

Connection Details

You’ll need to specify the host, port, user, password, and possibly the database.

  • host - Use the endpoint (you can find this in the Cloud Portal)

  • port - default is 3306

  • user - admin

Common Issues

Some of the issues you may encounter, and how to solve them:

  • Wrong Authentication Adapter - MySQL v8 authentication has some issues in SingleStore Helios and SingleStore recommends that you use a newer version. Sometimes you can work around this by specifying --default-auth=mysql_native_password in the connection details.

  • Binary Protocol - Use the text protocol when connecting to SingleStore Helios. You may need to disable server-side prepared statements (useServerPrepStmts=false).

  • Connection Failed - Check firewall configuration and perform other general connectivity troubleshooting.
