Fetch only not null columns from a table.

Question

How to fetch only not null columns from a table in sql server ?

For Example : Let us think there are 3 columns x1, x2 and x3 with 10 records.

If all the 10 record values of x3 column are null, Then I dont want to display that column. Only x1 and x2 needs to gets displayed.

I dont want to go for looping technique.
