SHOW STORAGE LIFECYCLE POLICIES¶

Lists the storage lifecycle policies for which you have access privileges.

You can use this command to list the storage lifecycle policies in the current database and schema for the session, a specified database or schema, or your entire account.

See also:: CREATE STORAGE LIFECYCLE POLICY , ALTER STORAGE LIFECYCLE POLICY , DESCRIBE STORAGE LIFECYCLE POLICY , DROP STORAGE LIFECYCLE POLICY

Syntax¶

SHOW STORAGE LIFECYCLE POLICIES
  [ LIKE '<pattern>' ]
  [ IN
        {
          ACCOUNT                  |

          DATABASE                 |
          DATABASE <database_name> |

          SCHEMA                   |
          SCHEMA <schema_name>     |
          <schema_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.

注釈

Using SHOW commands without an IN clause in a database context can result in fewer than expected results.

Objects with the same name are only displayed once if no IN clause is used. For example, if you have table t1 in schema1 and table t1 in schema2, and they are both in scope of the database context you've specified (that is, the database you've selected is the parent of schema1 and schema2), then SHOW TABLES only displays one of the t1 tables.

SCHEMA, . SCHEMA 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).

Output¶

The output of the command includes the following columns, which describe the properties and metadata of the object:

Column	Description
`created_on`	Date and time the policy was created.
`name`	The name of the policy.
`database_name`	The name of the database the policy is associated with.
`schema_name`	The name of the schema the policy uses.
`kind`	The type of storage lifecycle policy.
`owner`	The name of the role that created the policy.
`comment`	An optional comment that describes the policy.
`owner_role_type`	The type of role that the owner of the policy used to create the policy.
`options`	Optional parameters added to the policy to change how the policy behaves: `archive_for_days`: Number of days to archive rows before expiration. If this property isn't set for the policy, the value is NULL. `archive_tier`: The storage tier for the policy; COOl or COLD.

Access control requirements¶

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

Privilege	Object	Notes
APPLY STORAGE LIFECYCLE POLICY	Account	Allows SHOW on all storage lifecycle policies in the account.
APPLY	Storage lifecycle policy	Allows SHOW on the policy
OWNERSHIP	Storage lifecycle policy	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).

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 カスタムロールの作成.

For general information about roles and privilege grants for performing SQL actions on securable objects, see アクセス制御の概要.

Usage notes¶

The command returns a maximum of ten thousand records for the specified object type, as dictated by the access privileges for the role used to execute the command. Any records above the ten thousand records limit aren't returned, even with a filter applied.

To view results for which more than ten thousand records exist, query the corresponding view (if one exists) in the Snowflake Information Schema.

Examples¶

The following example lists the storage lifecycle policies that you have the privileges to view in the PUBLIC schema of the mydb database:

USE DATABASE mydb;

SHOW STORAGE LIFECYCLE POLICIES;
