Solution 2

Specify the column name in the Count function. When count is called with a specific column name, it ignores null.

SQL

SELECT COUNT(Col1) FROM Table1

SQL

SELECT COUNT(ColumnName) FROM TableName WHERE ColumnName IS NULL

EDIT
----------------------
I misread that.

hmm....you can count the columns in the table but i don't know if there is option to count null columns(I mean based on null values).
Count the number of columns in each TABLE[^]
Using this you can count NULL & NOT NULL columns(You need to do some changes in query)
In SQL Server 2005, how do you count the number of COLUMNS in a table?[^]
Counting non-blank columns[^]
