Add null value

[amiroh81]

Hello everyone,

There is QVD which contains four columns,

I would like to add a column where there are values ​​equal to NULL.

How do I do this?

Of course I can add a new column with a value other than NULL.

Thanks in advance everyone.

if(isnull(coulmn),'Y',coulmn)
