Schema:

ACCOUNT_USAGE

TAG_REFERENCES view¶

This Account Usage view can be used to identify the associations between objects and tags.

This view only records the direct relationship between the object and the tag. Tag inheritance is not included in this view.

The view is complementary to the information schema table function TAG_REFERENCES.

Columns¶

Column Name

Data Type

Description

TAG_DATABASE

TEXT

The database in which the tag is set.

TAG_SCHEMA

TEXT

The schema in which the tag is set.

TAG_ID

NUMBER

Internal/system-generated identifier for the tag. Note that for system tags this value is NULL.

TAG_NAME

TEXT

The name of the tag. This is the key in the key = 'value' pair of the tag.

TAG_VALUE

TEXT

The value of tag. This is the 'value' in the key = 'value' pair of the tag.

OBJECT_DATABASE

TEXT

Database name of the referenced object for database and schema objects. If the object is not a database or schema object, the value is empty.

OBJECT_SCHEMA

TEXT

Schema name of the referenced object (for schema objects). If the referenced object is not a schema object (e.g. warehouse), this value is empty.

OBJECT_ID

NUMBER

Internal identifier of the referenced object.

OBJECT_NAME

TEXT

Name of the referenced object if the tag association is on the object. If the tag association is on a column, Snowflake returns the parent table name.

OBJECT_DELETED

TIMESTAMP_LTZ

Date and time when the associated or parent object was dropped.

DOMAIN

TEXT

Domain of the reference object (e.g. table, view) if the tag association is on the object. For columns, the domain is COLUMN if the tag association is on a column. For more information, see supported domains.

COLUMN_ID

NUMBER

The local identifier of the reference column; not applicable if the tag association is not a column.

COLUMN_NAME

TEXT

Name of the referenced column; not applicable if the tag association is not a column.

APPLY_METHOD

TEXT

Specifies how the tag got assigned to the object.

  • CLASSIFIED: The tag was automatically applied to a column that was classified as containing sensitive data. See About tag mapping.

  • MANUAL: Someone manually set the tag on the object using a CREATE <object> command or ALTER <object> command. See Set a tag.

  • PROPAGATED: The tag was automatically propagated from one object to another. See Automatic tag propagation with user-defined tags.

  • NULL: Legacy record.

  • NONE: Legacy record.

Usage notes¶

  • Latency for the view may be up to 120 minutes (2 hours).

  • The view only displays objects for which the current role for the session has been granted access privileges.

  • The view does not contain information about columns that have been deleted.

  • The TAG_DATABASE_ID column is not included in this view. To obtain this value in your query result, perform a JOIN operation with the TAGS view.

Examples¶

Return the tag references for your Snowflake account:

select tag_name, tag_value, domain, object_id
from snowflake.account_usage.tag_references
order by tag_name, domain, object_id;
Copy

Return the active objects that have tag associations in your Snowflake account. The addition of the specified WHERE clause filters the objects that are deleted:

select tag_name, tag_value, domain, object_id
from snowflake.account_usage.tag_references
where object_deleted is null
order by tag_name, domain, object_id;
Copy
