LOL, the OhNoSecond strikes again.  One answer is
ISNULL(Value,'ReplacementValue').

Now whether this will work for a million records in near real time is
another question.

Subject: [dba-SQLServer] Appending strings where there are nulls

I am trying to build up a street address from a set of fields.  Any given
field may have a null.  If I just use + then anywhere there is a null in the
source I get a null as a result.  

What is the syntax to append fields to build an aliased field but avoid the
null issue?
