The USE WORKSPACE command changes the current cluster and database in the notebook.

Syntax

USE WORKSPACE { ID '<cluster_ID>' | '<cluster_name>' | @@CURRENT }
   [ IN GROUP { ID '<group_id>' | '<group_name>' } ]
   [ WITH DATABASE 'database_name' ]

Arguments

cluster_ID, cluster_name: ID or name of the cluster to use.
group_id, group_name: ID or name of the cluster group that contains the cluster.
database_name: Name of the SingleStore database to connect with.
