Connecting to Amazon Redshift

You can connect to your database using the following syntax.

The syntax elements are defined as follows.

  • cluster-name

    Your cluster's name.

  • account-number

    The unique identifier associated with your Amazon account number in a given Amazon Web Services Region. All clusters created by a given account in a given Amazon Web Services Region have the same account-number.

  • aws-region

    The code for the Amazon Web Services Region that the cluster is in.

  • database-name

    Your database's name.

For example, the following connection string specifies the my-db database in the my-cluster cluster in the us-east-1 Amazon Web Services Region.
