If we are looking at an integer column that has some null rows:
select day1, tickets1 from stats1;
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;
This blog help you implement Coalesce() function to delete the null rows from the columns. I hope this blog is adequate for eliminating the null rows.
