I want to insert a record into an SQL table only IF the value for that ID does not exist.

Example.
I have 4 fields.
listid, cusid, userid, Company

in one statement I want to:

INSERT values (cusid=null, userid=25, company=null)
  IF ((SELECT userid=25 AND comapny = NULL) = TRUE)

I hope I'm making sense :)

I know that the above is completly wrong syntax, but I thought it might share light on what I want to achive.
