Removing NULL from different columns in a table

Hi All,

I am wondering if there is any easy way to remove a LITERAL NULL from many different columns in a target table. I know to use ifthenelse condition for every columns. But there are many columns for my table and i want to do the same for many different jobs too.

So i am searching for a better way to do this. Please help me out.

Thanks in advance,
