DROP TAG

Removes a tag from the system.

See also:

CREATE TAG , ALTER TAG , SHOW TAGS

Syntax

DROP TAG [ IF EXISTS ] <name>;

Parameters

name

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:

Privilege

Object

Notes

OWNERSHIP

Tag

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 Access Control in Snowflake.

For additional details on tag DDL and privileges, see Managing Tags.

Usage Notes

  • Prior to dropping a tag, determine all of the objects the tag is assigned to by calling the Account Usage table function TAG_REFERENCES_WITH_LINEAGE.

  • A tag can be dropped if it is currently assigned to an object. If dropping the tag was unintentional, execute an UNDROP TAG command. Note that the UNDROP TAG command restores the tag assignments prior to the DROP TAG operation.

Example

The following example drops a tag:

drop tag cost_center;
