ALTER EXTERNAL CONNECTION

On this page Carat arrow pointing down

The ALTER EXTERNAL CONNECTION statement allows you to change the storage/sink URI that an external connection references.

You can use external connections to specify and interact with resources that are external to CockroachDB. When creating an external connection, you must define a name for the external connection while passing the provider URI and query parameters.

You can use ALTER EXTERNAL CONNECTION to update the connection string for an external connection to use a new authentication token. This allows you to rotate your auth token before the old token expires.

You can also use the following SQL statements to work with external connections:

Required privileges

To update an external connection, a user must have the UPDATE privilege on that connection.

For example:

icon/buttons/copy
GRANT UPDATE ON EXTERNAL CONNECTION backup_bucket TO user;
