Implement Coalesce in Snowflake

If we are looking at an integer column that has some null rows:

select day1, tickets1
from stats1;
day1 tickets1
2022-07-03 2
2022-05-08 null
2022-03-05 5

Rather than having the null, we can set that row to “0.” For doing that, we utilise the “coalesce()” function that gives the first not-null argument it has passed:

select day1, coalesce(tickets1, 3)
from stats1;
day1 tickets1
2022-04-05 2
2022-06-03 4
2022-01-08 5
