How to Use Snowflake Update Statement
Usually you only want to update rows that match a certain condition. You do this by specifying a WHERE clause:
--this will update only one row that matches id = 1
update sessions
set start_date = '2020-04-20 10:12:15.653',
end_date = '2020-04-22 15:40:30.123'
where id = 1;
--this will update multiple rows that match category = 1
update sessions
set end_date = null
where category = 1;To update all rows in a Snowflake table, just use the UPDATE statement without a WHERE clause:
update sessions
set end_date = '2020-04-04 16:57:53.653';You can also update multiple columns at a time:
update sessions
set start_date = '2020-04-02 14:05:15.400',
end_date = '2020-04-04 16:57:53.653';
