You can query the view ACCOUNT_USAGE.TABLES to find all ...The over() statement signals to Snowflake that you wish to use a windows function instead of the traditional SQL function, as some functions work in both contexts. A windows frame is a windows subgroup. Windows frames require an order by statement since the rows must be in known order.Since that's the case, using ANY_VALUE() will be faster for single queries but be careful of its effect on result set caching. ANY_VALUE() is a non deterministic function, so if something like a BI dashboard runs the query periodically between data changes on the tables, Snowflake will not be able to use the result set cache and have to run the query again.Instagram:https://instagram. libgenesis ionike indoor nationals 2023 qualifying standardsclassic seacraftpeloton floor bootcamp I like @Daniel Zagales answer but here is a work-around by using dense_rank and sum. with temp as ( select 'A' as usr, 1 as EventOrder, '60616' as Postal UNION ALL select 'A' as usr, 2 as EventOrder, '10000' as Postal UNION ALL select 'A' as usr, 3 as EventOrder, '60616' as Postal UNION ALL select 'B' as usr, 1 as EventOrder, '20000' as Postal UNION ALL select 'B' as usr, 2 as EventOrder ...Step 1: Connection to Snowflake.
