Column3 = @Param1 AND ...

SELECT Column1, Column2 FROM Table1 
WHERE 
Column3 = @Param1

Then I would get nothing in my result set if @Param2 is NULL for Column4.
Every Record has a value in Column 4. My intend is to retrieve all records that match @Param1 for Column3 regardless of the Column4 value when @Param2 is NULL>

Yes, I have.
When @Param2 has a value the results are as expected. When @Param2 is NULL, no results are returned. Also as expected because I have no records where Column4 is NULL.
What I would like to retrieve is everything that matches Column3.
