ALTER NOTEBOOK

Modifies the properties of an existing notebook.

Syntax

ALTER NOTEBOOK [ IF EXISTS ] <name> RENAME TO <new_name>

ALTER NOTEBOOK [ IF EXISTS ] <name> SET
  [ COMMENT = '<string_literal>' ]
  [ QUERY_WAREHOUSE = <warehouse_to_run_nb_and_sql_queries_in> ]
  [ IDLE_AUTO_SHUTDOWN_TIME_SECONDS = <number_of_seconds> ]
  [ SECRETS = ('<secret_variable_name>' = <secret_name>) [ , ... ] ]
Copy

Parameters

name

Specifies the identifier for the notebook to alter.

If the identifier contains spaces or special characters, the entire string must be enclosed in double quotes. Identifiers enclosed in double quotes are also case-sensitive.

For more information, see Identifier requirements.

RENAME TO new_name

Changes the name of the notebook to new_name. The new identifier must be unique for the schema.

For more details about identifiers, see Identifier requirements.

You can move the object to a different database and/or schema while optionally renaming the object. To do so, specify a qualified new_name value that includes the new database and/or schema name in the form db_name.schema_name.object_name or schema_name.object_name, respectively.

Note

  • The destination database and/or schema must already exist. In addition, an object with the same name cannot already exist in the new location; otherwise, the statement returns an error.

  • Moving an object to a managed access schema is prohibited unless the object owner (that is, the role that has the OWNERSHIP privilege on the object) also owns the target schema.

You cannot use the RENAME TO parameter to move a private notebook to a different database. If you want to move your notebook to another database to make the notebook available to others (for example, for shared use), create a new notebook in a different database, using your private notebook as a template. See Making a private notebook available for general use.

When an object is renamed, other objects that reference it must be updated with the new name.

SET ...

Sets one or more specified properties or parameters for the notebook:

QUERY_WAREHOUSE = warehouse_name

Specifies the warehouse where SQL queries in the notebook are run. This parameter is optional. However, it is required to run the EXECUTE NOTEBOOK command.

IDLE_AUTO_SHUTDOWN_TIME_SECONDS = number_of_seconds

Number of seconds of idle time before the notebook is shut down automatically. This parameter is only available for notebooks running on the container runtime. The value must be an integer between 60 and 259200 (72 hours).

Default: 3600 seconds

SECRETS = '(secret_variable_name' = secret_name [ , ... ])

Sets secret variables for the notebook.

  • secret_variable_name - The variable that will be used in the notebook cell when retrieving information from the secret.

  • secret_name - The name of the Snowflake secret.

UNSET ...

Unsets one or more specified properties or parameters for the notebook, which resets the properties to the defaults:

  • QUERY_WAREHOUSE

  • COMMENT

To unset multiple properties or parameters with a single ALTER statement, separate each property or parameter with a comma.

When unsetting a property or parameter, specify only the property or parameter name (unless the syntax above indicates that you should specify the value). Specifying the value returns an error.

Access control requirements

A role used to execute this SQL command must have the following privileges at a minimum:

Privilege

Object

Notes

USAGE or OWNERSHIP

Notebook

OWNERSHIP is a special privilege on an object that is automatically granted to the role that created the object.

The USAGE privilege on the parent database and schema are required to perform operations on any object in a schema.

For instructions on creating a custom role with a specified set of privileges, see Creating custom roles.

For general information about roles and privilege grants for performing SQL actions on securable objects, see Overview of Access Control.

Usage notes

  • Regarding metadata:

    Attention

    Customers should ensure that no personal data (other than for a User object), sensitive data, export-controlled data, or other regulated data is entered as metadata when using the Snowflake service. For more information, see Metadata fields in Snowflake.

Examples

The following example renames the notebook named my_notebook to notebook_v2:
