Identifier for the tag.
The identifier value must start with an alphabetic character and cannot contain spaces or special characters unless the entire identifier string is enclosed in double quotes (e.g.
"My object"). Identifiers enclosed in double quotes are also case-sensitive.
For more details, see Identifier Requirements.
Access Control Requirements¶
A role used to execute this SQL command must have the following privileges at a minimum:
OWNERSHIP is a special privilege on an object that is automatically granted to the role that created the object, but can also be transferred using the GRANT OWNERSHIP command to a different role by the owning role (or any role with the MANAGE GRANTS privilege).
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.
For additional details on tag DDL and privileges, see Managing Tags.
Restoring tags is only supported in the current schema or current database, even if the table name is fully-qualified.
If the tag was assigned to one or more objects when the DROP TAG command was executed, the UNDROP command restores the tag assignments to the objects. For details, see Tag Quotas for Objects & Columns.
If a tag with the same name already exists, an error is returned.
UNDROP relies on the Snowflake Time Travel feature. An object can be restored only if the object was deleted within the Data Retention Period. The default value is 24 hours.
The following example restores the most recent version of the tag named
UNDROP TAG cost_center;
