`semantic_view_database_id`	NUMBER	ID of the database to which the semantic view belongs.
`semantic_view_database_name`	VARCHAR	Database to which the semantic view belongs.
`data_type`	VARCHAR	Data type of the dimension expression.
`expression`	VARCHAR	The SQL expression used to calculate the dimension.
`synonyms`	ARRAY(VARCHAR)	List of the synonyms for the dimension.
`comment`	VARCHAR	Description of the dimension.
`created`	TIMESTAMP_LTZ	Creation time of the dimension.

Usage notes¶

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

Examples¶

Retrieve the list of all dimensions for the semantic view O_TPCH_SEMANTIC_VIEW in the database MY_DB:

SELECT * FROM SNOWFLAKE.ACCOUNT_USAGE.SEMANTIC_DIMENSIONS
  WHERE semantic_view_name = 'O_TPCH_SEMANTIC_VIEW'
    AND semantic_view_database_name = 'MY_DB';
