Thank you 回答1: If you mean with a select, I don't think there's a way to do it by table, you'd have to monitor the last executed queries to find that information: https://docs.snowflake.net/manuals/sql-reference/functions/query_history.html Update-wise: SYSTEM$LAST_CHANGE_COMMIT_TIME should give you the info you need. 来源： https:/

问题 I want to get the last accessed timestamp for a table in the snowflake 回答1: Not always ideal, but a quick way to find this for one-off questions is to use QUERY_HISTORY SELECT START_TIME, * FROM TABLE(INFORMATION_SCHEMA.QUERY_HISTORY()) WHERE QUERY_TEXT LIKE '%MYSCHEMA.MYTABLE%'; Update : Query to specifically get just the most recent query time.
