Usage Notes¶

Latency for the view may be up to 90 minutes.
The view does not recognize the MANAGE GRANTS privilege and consequently may show less information compared to a SHOW command executed by a user who holds the MANAGE GRANTS privilege.
Querying the SUM(BYTES) for a table does not represent the total storage usage, because the amount does not include Time Travel and Fail-safe usage.

Examples¶

Retrieve the total size (in bytes) of all active tables in all schemas in your account:

SELECT TABLE_SCHEMA,SUM(BYTES)
    FROM snowflake.account_usage.tables
    WHERE DELETED IS NULL
    GROUP BY TABLE_SCHEMA;
