  SHOW SNOWFLAKE.DATA_PRIVACY.CUSTOM_CLASSIFIER           |
  SHOW SNOWFLAKE.DATA_PRIVACY.CUSTOM_CLASSIFIER INSTANCES
}
  [ LIKE <pattern> ]

    {
      ACCOUNT                  |

      DATABASE                 |
      DATABASE <database_name> |

Parameters¶

LIKE 'pattern'

Optionally filters the command output by object name. The filter uses case-insensitive pattern matching, with support for SQL wildcard characters (% and _).

For example, the following patterns return the same results:

... LIKE '%testing%' ...

... LIKE '%TESTING%' ...

. Default: No value (no filtering is applied to the output).

[ IN ... ]

Optionally specifies the scope of the command. Specify one of the following:

ACCOUNT

Returns records for the entire account.

DATABASE, . DATABASE db_name

Returns records for the current database in use or for a specified database (db_name).

If you specify DATABASE without db_name and no database is in use, the keyword has no effect on the output.

SCHEMA, . SCHEMA schema_name, . schema_name

Returns records for the current schema in use or a specified schema (schema_name).

SCHEMA is optional if a database is in use or if you specify the fully qualified schema_name (for example, db.schema).

If no database is in use, specifying SCHEMA has no effect on the output.

Default: Depends on whether the session currently has a database in use:

Database: DATABASE is the default (that is, the command returns the objects you have privileges to view in the database).
No database: ACCOUNT is the default (that is, the command returns the objects you have privileges to view in your account).

Access control requirements¶

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

Privilege	Object	Notes
OWNERSHIP	The custom classification instance.	Users with the ACCOUNTADMIN admin role can list instances with this command.

Note that operating on any object in a schema also requires the USAGE privilege on the parent database and 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.

Output¶

Provides custom classifier instance properties and metadata in the following columns:

Column	Description
created_on	Date and time when the custom classification instance was created.
name	Name of the custom classification instance.
database_name	Database that stores the custom classification instance.
schema_name	Schema that stores the custom classification instance.
current_version	The version of the custom classification instance. Snowflake automatically updates the version number.
comment	Comment for the custom classification instance.
owner	The role that owns the custom classification instance.
