  create table tbltests(id int ,id1 int)

  insert into tbltests(id,id1) values

  (1,2),(2,1),(3,null),(4,5),(5,4)

  I want if row like

  2 1

  then only one row selected

  as 1 2.

  if

  3 null

  then it also should fetch with select query.

  Please reply.

  3 null

  4 5

  SELECT t1.id,t1.id1

  FROM tbltests t1

  WHERE NOT EXISTS(SELECT * FROM tbltests t2

  WHERE t2.id = t1.id1

  AND t2.id1 = t1.id

  AND t2.id < t2.id1)
