Can someone please help me as I am new to SQL and having a bit of trouble
with an assignment. Problem is:

I need to create a single textfile with a statement that addresses the
following:

This query is about tracks that have the same length on the same album. For
each pair of such tracks, display one row showing the length, the album
code, and the title of each matching track,

e.g. 191     7599-27313-2      Dont Stop     I dont want to know

cannot show the same pair of tracks more than once, i.e with the track
titles swapped around.

      191    7599-27313-2     Dont Stop          I dont want to know
      191   7599-27313-2      I dont want to know           Dont Stop.

What I have done so far is,

    Select Length,AlbumCode,TrackTitle from Tracks
Group by Length,AlbumCode,Tracktitle
having count (Length) >1;

but of course query is looking for Length,AlbumCode and Tracktitle which has
a count greater than 1...Result NIL

How can I get around this?????
