Couple of ways to pull this off, but try this one..
SELECT 
   COALESCE(lastName, '') +
   CASE WHEN lastName IS NULL THEN ' ' END + 
   COALESCE(firstName, '') as FullName

Open in new window

With any expression where you're adding values, if one of the values is NULL then the entire expression evaluates to NULL.

You can use ISNULL function:

select ISNULL(lastName,'') +' '+ISNULL(firstName,'') as fullName
