CREATED |
TIMESTAMP_LTZ |
Creation time of the view. |
LAST_ALTERED |
TIMESTAMP_LTZ |
Date and time the object was last altered by a DML, DDL, or background metadata operation. See Usage Notes. |
LAST_DDL |
TIMESTAMP_LTZ |
Timestamp of the last DDL operation performed on the table or view. All supported table/view DDL operations update this field:
All ALTER TABLE operations update this field, including setting or unsetting a table parameter (for example, COMMENT, DATA_RETENTION_TIME, etc.) and changes to table columns (ADD / MODIFY / RENAME / DROP). For more information, see the Usage Notes. |
LAST_DDL_BY |
TEXT |
The current username for the user who executed the last DDL operation. If the user has been dropped, shows
For dropped users, you can join the |
COMMENT |

Comment for this view. |
Usage notes¶
The view only displays objects for which the current role for the session has been granted access privileges. The view does not honor the MANAGE GRANTS privilege and consequently may show less information compared to a SHOW command when both are executed with a role that was granted the MANAGE GRANTS privilege.
This behavior also applies to other account-level privileges and Information Schema views for which there is a corresponding SHOW command.
To remove the INFORMATION_SCHEMA views from your queries, filter using a WHERE clause, e.g.:
... WHERE table_schema != 'INFORMATION_SCHEMA'
The LAST_ALTERED column is updated when the following operations are performed on an object:
DDL operations.
DML operations (for tables only). This column is updated even when no rows are affected by the DML statement.
Background maintenance operations on metadata performed by Snowflake.
For views and tables, use the LAST_DDL column for the last modification time for an object.
The value in the LAST_DDL column is updated as follows:
When a table or view is created, the LAST_DDL timestamp is the same as the CREATED timestamp.
When a table or view is dropped, the LAST_DDL timestamp is the same as the DELETED timestamp.
Last DDL data is not available for operations that occurred before the columns were added. The new DDL fields contain
null
until a DDL operation is executed.For replicated databases, the LAST_DDL and LAST_DDL_BY fields are only updated for objects in the primary database. After failover, the LAST_DDL and LAST_DDL_BY fields are updated for DDL operations for the tables and views in the newly promoted primary database. These fields will remain unchanged for objects in the now secondary database.
For objects in secondary databases that are newly created during a refresh operation, these fields are
null
