It is a tradition on youtube that many channels do not get number of subscribers and views that they actually deserve. Your sql videos are among the best ones in terms of their quality and hardness

Hello ankit,
I tried adding more rows will null values in them and then run the coalesce function but is returns only the first value in all 3 nulls instead of different values.
Am I understanding it wrong?
Here is my code :
Select *, isnull(age, 8), coalesce(age, 9, 10)
from customer

When I use ISNULL(salary, 0)
It's not passing the value 0 to my empty fields 😊
