Syntax

USE [DATABASE | ORGANIZATION | ROLE | SCHEMA | STORE] entity_name;

Description

This switches the current session’s , , , , or .

Arguments

entity_name

The name of an existing entity to set as the user’s current for the active session. Use to persist the change for new sessions. if tshe name is case sensitive you must wrap it in double quotes; otherwise the system uses the lowercase name.

When using a new schema, a fully-qualified schema name can optionally be used to set the current database and schema.

Examples

Use a new organization

In the following example, we have access to different organizations, and we switch to the demo2 organization in the current sessions from the test organization:

<no-db>/<no-store># LIST ORGANIZATIONS;
+--------------------------------------+------------+-------------+-------------+--------------+--------------------+-------------------------------+
|  ID                                  |  Name      |  Is Current |  Is Default |  Description |  Profile Image Uri |  Created At                   |

+--------------------------------------+------------+-------------+-------------+--------------+--------------------+-------------------------------+

Use a new database

In the following example, we are creating a new database called demodb2 and using it. Note the database in the command line prompt changing from demodb to demodb2:

demodb.public/demostore# CREATE DATABASE demodb2;
+------------+----------------+------------+------------------------------------------+
|  Type      |  Name          |  Command   |  Summary                                 |
+============+================+============+==========================================+
| database   | demodb2        | CREATE     | database demodb2 was successfully        |
|            |                |            | created                                  |
+------------+----------------+------------+------------------------------------------+
| schema     | demodb2.public | CREATE     | schema demodb2.public was successfully   |
|            |                |            | created                                  |
+------------+----------------+------------+------------------------------------------+
demodb.public/demostore# LIST DATABASES;
+------------+-------------+------------+-------------------------------+
|  Name      |  Is Default |  Owner     |  Created At                   |
+============+=============+============+===============================+
| demodb2    | false       | sysadmin   | 2024-05-07 18:23:24 +0000 UTC |
+------------+-------------+------------+-------------------------------+
| demodb     | true        | sysadmin   | 2024-05-07 18:19:38 +0000 UTC |
+------------+-------------+------------+-------------------------------+
demodb.public/demostore# USE DATABASE demodb2;
+------------+------------+------------+------------------------+
|  Type      |  Name      |  Command   |  Summary               |
+============+============+============+========================+
| database   | demodb2    | USE        | using database demodb2 |
+------------+------------+------------+------------------------+
demodb2.public/demostore#

Use a new schema

In the following example, we switch from the current public schema to use a new schema called newschema. Note how after the command is issued, the session's schema changes from public to newschema:

demodb.public/demostore# LIST SCHEMAS;
+------------+-------------+------------+-------------------------------+
|  Name      |  Is Default |  Owner     |  Created At                   |
+============+=============+============+===============================+
| public     | true        | sysadmin   | 2024-05-07 18:19:38 +0000 UTC |
+------------+-------------+------------+-------------------------------+
| newschema  | false       | sysadmin   | 2024-05-07 18:20:03 +0000 UTC |
+------------+-------------+------------+-------------------------------+
demodb.public/demostore# USE SCHEMA newschema;
demodb.newschema/demostore#

Use a new store

The following shows how msk store is set as the current store for the session to use:

demodb.public/demostore# LIST STORES;
+-------------+------------+----------------+------------+-------------+------------+-------------------------------+-------------------------------+
|  Name       |  Type      |  Access Region |  State     |  Is Default |  Owner     |  Created At                   |  Updated At                   |
+=============+============+================+============+=============+============+===============================+===============================+
| msk         | Kafka      | AWS us-east-1  | ready      | false       | sysadmin   | 2024-05-07 18:16:39 +0000 UTC | 2024-05-07 18:16:39 +0000 UTC |
+-------------+------------+----------------+------------+-------------+------------+-------------------------------+-------------------------------+
| demostore   | Kafka      | AWS us-east-1  | ready      | true        | sysadmin   | 2024-05-07 18:16:07 +0000 UTC | 2024-05-07 18:16:07 +0000 UTC |
+-------------+------------+----------------+------------+-------------+------------+-------------------------------+-------------------------------+
demodb.public/demostore# USE STORE msk;
+------------+------------+------------+-----------------+
|  Type      |  Name      |  Command   |  Summary        |
+============+============+============+=================+
| store      | msk        | USE        | Using store msk |
+------------+------------+------------+-----------------+
demodb.public/msk#

Use a new role

The following example shows how you can update the current role to useradmin to allow managing users and roles in the current session:

demodb.public/demostore# USE ROLE useradmin;
+------------+------------+------------+------------------------+
|  Type      |  Name      |  Command   |  Summary               |
+============+============+============+========================+
| role       | useradmin  | USE        | using role "useradmin" |
+------------+------------+------------+------------------------+
demodb.public/demostore# LIST ROLES;
+---------------+-------------+-------------+-------------------------------+-------------------------------+
|  Name         |  Is Current |  Is Default |  Created At                   |  Updated At                   |
+===============+=============+=============+===============================+===============================+
| public        | false       | false       | 2024-05-07 18:07:22 +0000 UTC | 2024-05-07 18:07:22 +0000 UTC |
+---------------+-------------+-------------+-------------------------------+-------------------------------+
| orgadmin      | false       | false       | 2024-05-07 18:07:22 +0000 UTC | 2024-05-07 18:07:22 +0000 UTC |
+---------------+-------------+-------------+-------------------------------+-------------------------------+
| securityadmin | false       | false       | 2024-05-07 18:07:22 +0000 UTC | 2024-05-07 18:07:22 +0000 UTC |
+---------------+-------------+-------------+-------------------------------+-------------------------------+
| useradmin     | true        | false       | 2024-05-07 18:07:22 +0000 UTC | 2024-05-07 18:07:22 +0000 UTC |
+---------------+-------------+-------------+-------------------------------+-------------------------------+
| sysadmin      | false       | true        | 2024-05-07 18:07:22 +0000 UTC | 2024-05-07 18:07:22 +0000 UTC |
