In a sql server 2008 r2 database column that is defined as varchar, how do you check to see if the field contains all spaces regardless of the length the field is?

A few different ways you can do this, see in red below:
DECLARE @x VARCHAR(32) = '         ';
SELECT
	CASE WHEN LTRIM(@x) = '' THEN 'All spaces' ELSE 'Not all spaces' END ,
	CASE WHEN LEN(@x) = 0 THEN 'All spaces' ELSE 'Not all spaces' END ,
	CASE WHEN REPLACE(@x,' ','') = '' THEN 'All spaces' ELSE 'Not all spaces' END ,
	CASE WHEN NULLIF(@x,'') IS NULL THEN 'All spaces' ELSE 'Not all spaces' END ;
