I'm trying to concatenate the values in multiple columns into a string in another column.

Here is some SQL:
CREATE TABLE #tmpExample ( 
    column1 varchar(255),
    column2 varchar(255),
    column3 varchar(255),
	column4 varchar(255)
INSERT INTO #tmpExample  
('1', 'A', 'B', 'C'),
('2', 'D', 'E', 'F'),
('3', 'G', 'H', 'I'),
('4', '', '4', 'ME');

ALTER TABLE #tmpExample
ADD columns2_4 varchar(255)

Given that data I would like to write a statement that results in the following in "columns2_4":

I'm hungry right now and so I'm thinking ISNULL(COLUMN2, 'PIZZA').

Actually any NULL in column 2,3, or 4 should return pizza (I'm REALLY hungry).
