  I have four fields:

  FirstName varchar(20),null

  MiddleName varchar(5),null

  LastName varchar(30),null

  Position int,null

  How to concatenate all these four fields to give result as Name?

  I tried this but it is not working properly.

  select

  LTRIM(RTRIM(isnull(Person.Lastname,' ')+','+isnull(Person.Firstname,' ')+' '+ISNULL(Person.middlename,' ')))+' '+CAST(person.Position as varchar) as Name

  from dbo.Person

  Any suggestions?

  I am guessing you are getting NULL when Position IS NULL? All you need to do is wrap your Position cast inside an ISNULL like the other columns.
