SQL Help

[neemi]

Hi All,
I need help with a bit of SQL...

I have a table which shows the below:

season | ValueThisYear
AW17-1 | 100
AW17-2 | 205
AW18-1 | 199
AW18-2 | 300

I need to create a view based on similar columns which will give me the data as below. ie. ValueThisYear and ValueLastYear. where season is AW18-1 the value this year is 199 and the value Last year is taken from AW17-1 being 100.

I need the view result showing as below:

season | ValueThisYear | ValueLastYear
AW17-1 | 100 |
AW17-2 | 205 |
AW18-1 | 199 | 100
AW18-2 | 300 | 205


Thanks in advance
Nims

And how do you know which record is for this year and which is for the last one?
Don't tell me "by the name" please.

“ValueThisYear” is the result of a report.

You need to get to the data from which that report was generated. Must have DATES!

I assume the 17 and 18 are years but it would have been appropriate for neemi to clarify in the original post. Also use of TGML is a must for members who have started over 200 threads in 18 years.

I expect something like this would work. At least it gives the same results as requested

WITH 
cteA AS
(
 SELECT 'AW17-1' Season, 100 ValueThisYear UNION 
 SELECT 'AW17-2', 205 UNION
 SELECT 'AW18-1', 199 UNION
 SELECT 'AW18-2', 300
 )
 SELECT A.SEASON, A.ValueTHisYear, B.ValueTHisYear ValueLastYear
 FROM cteA A LEFT JOIN cteA B ON
  LEFT(A.Season,2) = Left(B.Season,2) AND 
  RIGHT(A.Season,1) = Right(B.Season,1) AND 
  Convert(int,SUBSTRING(A.Season,3,2)) = Convert(int,SUBSTRING(B.Season,3,2))+1
