How to Use Coalesce in Snowflake

In Snowflake, we can find the integer columns that have some null rows To remove that, we use the “coalesce()” function. In this blog, you will learn to remove the null rows using the “Coalesce()” function.

Implement Coalesce in Snowflake

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

select day1, tickets1
from stats1;
day1tickets1
2022-07-032
2022-05-08null
2022-03-055

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;
day1tickets1
2022-04-052
2022-06-034
2022-01-085
