Below is the table and desired results:

[Week] float,

[Month] float,

[C#] float,

[Dept] nvarchar(255)

,[Issue] nvarchar(255), [Type] nvarchar(255), [Dept age] nvarchar(255))

--===== All Inserts into the IDENTITY column

INSERT INTO #cs

([Year], [ Week], [ Month], [C#],[Dept],[Issue], [Type], [Dept age])

SELECT 2015, 14, 4, 188, D1,I1,T1, 5 UNION ALL

SELECT 2015, 14, 4, 452,d1, I1, T2, 5 UNION ALL

SELECT 2015, 14, 4, 63, d1, I1, T1, 6 UNION ALL

SELECT 2015, 14, 4, 9, d1,I2, T1, 7 UNION ALL

SELECT 2014, 14, 4, 187, D1,I1,T1, 5 UNION ALL

SELECT 2014, 14, 4, 451,d1, I1, T2, 5 UNION ALL

SELECT 2014, 14, 4, 62, d1, I1, T1, 6 UNION ALL

SELECT 2014, 14, 4, 10, d1,I2, T1, 7 UNION ALL,

select 2014, 14, 4, 199, d1, i3, t1, 8 UNION ALL,

select 2012, 14,4,200, d1, i5, t1, 8 UNION ALL,

Select 2014, 15, 4,200, d1, i1, t1, 10 UNION ALL,

Select 2013, 15, 4, 400, d1, i1, t1, 12)

Desired Result:

Week, Month, C1#,c2# Dept,Issue, Type, Dept age

14, 4 188 187 d1 i1 t1 5

14, 4 452 451 d1 i1 t2 5

15, 4, 200, 400, d1, i1, t1, 12

14, 4, 0 199 d1, i3, t1, 8

14,4,0 0, d1, i5, t1, 8

i.e Requirements

Condition 1)

I WANT two columns C1# and C2# in result table, where C1# contains data from 2015 for respective (Month, week, Dept, issue, type, dept age) combination and C2# contains data from previous year (2014) for respective (Month, week, Dept, issue, type, dept age) combination.

e.g. Week, Month, C1#,c2# Dept,Issue, Type, Dept age

14, 4 188 187 d1 i1 t1 5

Condition 2)

If 2015 data is not present for perticular week, then C1# will contain data of 2014 for same respective combination and C2# will contain data of 2013.

e.g.

Week, Month, C1#,c2# Dept,Issue, Type, Dept age

15, 4, 200, 400, d1, i1, t1, 12

Condition 3)

If for a perticular week 2015 data doesn't exist for any (Dept,Issue, Type, Dept age) combination but other (Dept,Issue, Type, Dept age) combination data exist for the same week in 2015 then c1 should be null or 0 for the combination where it doesn't exist

e.g

Week, Month, C1#,c2# Dept,Issue, Type, Dept age

14, 4, 0 199 d1, i3, t1, 8

14,4,0 0, d1, i5, t1, 8

Note: Condition 1 and 2 are meeting from the above posted query, but condition 3 is not meeting.

Hope this helps.and sorry for trouble.

Any solution wil be helpful.

Nice attempt at posting ddl and sample data. Unfortunately the table definition is incomplete and the sample data won't run as posted.

Why in the world are you storing Year and the other columns as floats??? Why not use a date or datetime column? The biggest challenge I have here is that it is not at all clear what the logic is to get your expected results.

Here is the updated table:

create table #cs([Year] float,

[Week] float,

[Month] float,

[C#] float,

[Dept] nvarchar(255)

,[Issue] nvarchar(255), [Type] nvarchar(255), [Dept age] nvarchar(255))

This is how data is stored since long time.

Storing integers as floats is crazy. :w00t:

Your sample data is not usable because the query is nowhere close to running as posted. I could clean it up but it still isn't clear what the logic needs to be. Can you try to explain more clearly what the business rules are here?

Ok. So here are the better explanation (hope this will help)

i want a result table with below columns:

Week, Month, C1#,c2# Dept,Issue, Type, Dept age

where C1 is C# for perticular week, year (2015, w1) if data for that perticular week in 2015 exist for any combination of (Dept,Issue, Type, Dept age) but if for a perticular combination data in 2015 doesn't exist then c1 will be null. If there doesn't exist any data for any combination of (Dept,Issue, Type, Dept age) in (2015,w1) then c1 will take value of 2014.

C2 is C# for previous year in respective week (2014, w1) for respective c1 conbination of (Dept,Issue, Type, Dept age). Same as above: if for perticular combination of (Dept,Issue, Type, Dept age), data doesn't exist in (2014,w1) then it will be null.

hope this helps let me know for any confusion.

Sean Lange SSC Guru Points: 286562 More actions · Answer 5

Taking your various posts I was able to piece together ddl and sample data.



create table #cs

(

	[Year] float,

	[Week] float,

	[Month] float,

	[C#] float,

	[Dept] nvarchar(255),

	[Issue] nvarchar(255),

	[Type] nvarchar(255),

	[Dept age] nvarchar(255)

)

INSERT INTO #cs

([Year], [Week], [Month], [C#], [Dept], [Issue], [Type], [Dept age])

SELECT 2015, 14, 4, 188, 'D1', 'I1', 'T1', 5 UNION ALL

SELECT 2015, 14, 4, 452, 'd1', 'I1', 'T2', 5 UNION ALL

SELECT 2015, 14, 4, 63, 'd1', 'I1', 'T1', 6 UNION ALL

SELECT 2015, 14, 4, 9, 'd1', 'I2', 'T1', 7 UNION ALL

SELECT 2014, 14, 4, 187, 'D1', 'I1', 'T1', 5 UNION ALL

SELECT 2014, 14, 4, 451, 'd1', 'I1', 'T2', 5 UNION ALL

SELECT 2014, 14, 4, 62, 'd1', 'I1', 'T1', 6 UNION ALL

SELECT 2014, 14, 4, 10, 'd1', 'I2', 'T1', 7 UNION ALL

select 2014, 14, 4, 199, 'd1', 'i3', 't1', 8 UNION ALL

select 2012, 14, 4, 200, 'd1', 'i5', 't1', 8 UNION ALL

Select 2014, 15, 4, 200, 'd1', 'i1', 't1', 10 UNION ALL

Select 2013, 15, 4, 400, 'd1', 'i1', 't1', 12

select *

from #cs

What doesn't make sense is the output. I can't even begin to comprehend what you are trying to do.

Nothing about your expected results makes sense to me at this point. You have 12 rows in your base table but only 5 coming out and the logic for the values I am 100% not getting.

First attempt on getting this query working using Sean's sample data.



WITH cteCs AS(

    select *,

        ROW_NUMBER() OVER(PARTITION BY  [Week], [Month], [Dept], [Issue], [Type], [Dept age] ORDER BY [Year] DESC) rn

    from #cs

)

SELECT [Week],

    [Month],

    CASE WHEN MAX( CASE WHEN rn = 2 THEN [C#] END) IS NULL

            THEN 0

            ELSE MAX( CASE WHEN rn = 1 THEN [C#] END) END AS [C#1],

    COALESCE( MAX(CASE WHEN rn = 2 THEN [C#] END), MAX( CASE WHEN rn = 1 THEN [C#] END), 0) AS [C#2],

    [Dept],

    [Issue],

    [Type],

    [Dept age]

FROM cteCs

GROUP BY [Week],

    [Month],

    [Dept],

    [Issue],

    [Type],

    [Dept age];

Just how many different threads have you started asking this very same question???

Are wondering why you aren't getting much help?? Could be because people are all over the place trying to help but those trying don't see what others are doing as well.

You need to pay attention to details when you post. Please look at that mess of a table definition and data. I cleaned it once for you because what you posted won't work. I am beginning to get the feeling you don't really want any help.

Still have NO IDEA how you are wanting us to query the data.

This isn't what you need but it is the only way I can seem to explain what we need:

Are we doing this:

SELECT * FROM YourTable; -- Actual query will generate the required result set

OR

SELECT * FROM YourTable WHERE ??????; -- Where the ?'s are the criteria by which the data is selected
