How do I get the count of null value columns per row in a return set?

Question

I\'m looking for a query which will return me an extra column at the end of my current query which is the count of all columns within the return set which contain a null column.

Answer 1

If there isnt a very good reason you need to do this in the SQL, you should just do a for loop through the result set and count the NULL vlues then.

The cost goes from n^n to n..
