CONNECT <user>[/<password>][@<connection string>];
Using this command, you can establish a new connection with Exasol.
If a connection already exists, this connection will be disconnected when a new connection is successfully established. If no password is specified, then you will be requested enter the password by EXAplus. If <connection string> is not specified, the information of the last connection is used. A COMMIT will also be performed if "SET AUTOCOMMIT EXIT" has been set.
