Hi here is my sql code, tested and works :
select t.CityName As 'CityName1',t.CityTemp
As 'CityTemp1' ,t1.CityName As 'CityName2',t1.CityTemp
As 'CityTemp2',(t1.CityTemp-t.CityTemp)*(-1) As Difftemp
From Test as t inner join Test As t1
on
t1.CityId=t.CityId+1
Result is :
Delhi 40 Mumbai 35 5
Mumbai 35 Jammu 32 3
Jammu 32 Pune 18 14
If you want to remove the CityTemp1, CityTemp2, you can do
so from select statement. :)
