Connect with MySQL Client

SingleStore is wire-compliant with MySQL meaning connecting to SingleStore is as easy as connecting to a MySQL database. You may need the -u <user>, -h <host>, and -P <port> flags to ensure you are connecting to SingleStore properly. For example:

Shell

mysql -u root -h 127.0.0.1 -P 3306

where,

-u: Specifies the name of the SingleStore database user.
-h: Specifies the IP address or hostname of the SingleStore deployment.
-P: Specifies the port to connect to. Default: 3306.

You may also use the --prompt flag to change the prompt in the interactive session, simply to help distinguish SingleStore from MySQL:

Shell

mysql -u root -h 127.0.0.1 -P 3306 --prompt="singlestore> "

The output when you connect should look similar to this:

Important

The @@version and @@version_comment global variables are for compatibility with MySQL clients, which expect certain minimum version numbers and strings to be present. To check the real version of SingleStore you are running, use the @@memsql_version variables instead. To check the license you are running, see the license_key and license_type status codes.
