I have the following function that simply returns a number of hyphens equal to the argument length passed in to the function. However, it only returns one hyphen.
Alter Function CreateWhiteSpace (@WhiteSpaceCount Int)
Returns char(32)
Declare @I Int
Declare @WhiteSpace Char(32)
Set @I = 0 
	While @I <= @WhiteSpaceCount
			Set @WhiteSpace = COALESCE(@WhiteSpace,'-') + '-'
			Set @I = @I + 1
return @WhiteSpace
