Getting the max from two combined columns - sql

I'm trying to get the value from all accounts in use, using the combination of two columns (Year and month) to get the right period.
The data table looks like this:
Account
Year
Month
Value
1000
2015
1
11501
1000
2016
1
11111
1000
2016
10
11610
1000
2017
1
11701
2000
2014
12
22222
2000
2017
1
21701
3000
2015
1
33333
4000
2016
1
44444
Table: AcBal
I've tried to make an query, but somehow, I cant quite get there...
Select Account,
Year,
Month,
MAX(((Year*100)+Month)) AS YearPeriod,
Value
from AcBal
where YearPeriod <= 201601
group by Account, Year, Month, Value
order by Account, Year
If I use "where year <= 2017", then I get a result, but with multiple hits for each accout. I only want one result for each account.
Wanted result:
Account
Year
Month
Value
1000
2016
1
11111
2000
2014
12
22222
3000
2015
1
33333
4000
2016
1
44444
How can I achieve that?

You could use TOP (1) WITH TIES and ROW_NUMBER() OVER() like the following query
Select TOP (1) WITH TIES
Account, [Year], [Month], [Year]*100+[Month] AS YearPeriod , Value
from AcBal
where [Year]*100+[Month] <=201601
ORDER BY ROW_NUMBER() OVER(PARTITION BY Account ORDER BY [Year]*100 +[Month] DESC)

Use HAVING:
Select Account, Year, Month, MAX(((Year*100)+Month)) AS YearPeriod , Value
from AcBal
group by Account, Year, Month, Value
Having MAX(((Year*100)+Month)) <=201601
order by Account, Year

Percent of change by year and month

I have code that distinctly counts authorizations grouped by month and year.
I added a calculated field to show the percent of change but my issue is I only want to get this percentage between the years by month.
My code calculates the percent for each previous row. which when pulled into SSRS displays the incorrect value after the for column.
Select D.Month
,D.Year
,count( distinct D.authorization_number) [Admission Events]
,CAST(lag(Count(distinct D.authorization_number), 1) over (order by D.month) - Count(distinct D.authorization_number) as FLOAT) / CAST(Count(distinct D.authorization_number)as FLOAT) [Admission Events Pct]
From #Detail D
Group BY D.Month
,D.Year
In these results I would like to only display the pct for year 2018 in SSRS.
Month Year Admission Events Admission Events Pct
1 2017 5919 NULL
1 2018 6057 -0.0227835562159485
2 2017 5302 0.142399094681252
2 2018 5234 0.0129919755445166
3 2017 5548 -0.0565969718817592
3 2018 5389 0.0295045462980145
4 2017 5128 0.0508970358814353
4 2018 5503 -0.0681446483736144
5 2017 5768 -0.0459431345353675
5 2018 5708 0.0105115627189909
6 2017 5461 0.0452298113898553
6 2018 2606 1.09554873369148
Is this what you want?
select t.*
from (<your query here>) t
where year = 2018;
You need a subquery or CTE so the where doesn't interfere with the lag().

Oracle sql: Order by with GROUP BY ROLLUP

I'm looking everywhere for an answer but nothing seems to compare with my problem. So, using rollup with query:
select year, month, count (sale_id) from sales
group by rollup (year, month);
Will give the result like:
YEAR MONTH TOTAL
2015 1 200
2015 2 415
2015 null 615
2016 1 444
2016 2 423
2016 null 867
null null 1482
And I would like to sort by total desc, but I would like year with biggest total to be on top (important: with all records that compares to that year), and then other records for other years. So I would like it to look like:
YEAR MONTH TOTAL
null null 1482
2016 null 867
2016 1 444
2016 2 423
2015 null 615
2015 2 415
2015 1 200
Or something like that. Main purpose is to not "split" records comparing to one year while sorting it with total. Can somebody help me with that?
Try using window function max to get max of total for each year in the order by clause:
select year, month, count(sale_id) total
from sales
group by rollup(year, month)
order by max(total) over (partition by year) desc, total desc;
Hmmm. I think this does what you want:
select year, month, count(sale_id) as cnt
from sales
group by rollup (year, month)
order by sum(count(sale_id)) over (partition by year) desc, year;
Actually, I've never use window functions in an order by with a rollup query. I wouldn't be surprised if a subquery were necessary.
I think you need to used GROUPING SETS and GROUP_ID's. These will help you determine a NULL caused by a subtotal. Take a look at the doc: https://docs.oracle.com/cd/B19306_01/server.102/b14223/aggreg.htm

Getting Monthly Data

I want to extract all budget entries charged to the current year and cumulated over each month after .In January, taking the total over January, February take accumulated of January plus accumulated February...
I started with this query :
IF OBJECT_ID('tempdb..#BudgetTransTmp') IS NOT NULL
DROP TABLE #BudgetTransTmp
Select
Row_number() over(ORDER BY YEAR(BTLine.DATE),MONTH(BTLine.DATE)) as RowNumber,
COMBINATION.DISPLAYVALUE,
BTLine.LedgerDimension AS LedgerDimension,
MIN(BTLine.TransactionCurrencyAmount) AS Amount,
SUM(BTLine.TransactionCurrencyAmount)
OVER (ORDER BY YEAR(BTLine.DATE),MONTH(BTLine.DATE),BTLine.LedgerDimension,COMBINATION.DISPLAYVALUE ) AS SUM,
YEAR(BTLine.DATE) AS Year ,
MONTH(BTLine.DATE) AS MONTH
INTO #BudgetTransTmp
FROM MicrosoftDynamicsAX.dbo.BudgetTransactionLine AS BTLine
--Get Display value
INNER JOIN MicrosoftDynamicsAX.dbo.DIMENSIONATTRIBUTEVALUECOMBINATION AS COMBINATION
ON COMBINATION.RECID = BTLine.LEDGERDIMENSION
GROUP BY
BTLine.LedgerDimension,
YEAR(BTLine.DATE),
MONTH(BTLine.DATE)
ORDER BY RowNumber
The result is :
LedgerDimension Amount SUM Year Month Display
1 22565448266 850.00 850.00 2012 8 601200-001-027--
2 22565448265 1700.00 2550.0 2012 12 601200-002-027--
3 22565448266 2700.00 5250.00 2012 12 601200-001-027--
4 22565448267 650.00 5900.00 2012 12 601400-002-027--
5 22565448268 1100.00 7000.00 2012 12 601400-001-027--
But i want to get
LedgerDimension Amount SUM Year Month Display
1 22565448266 850.00 850.00 2012 8 601200-001-027--
2 22565448265 1700.00 1700.0 2012 12 601200-002-027--
3 22565448266 2700.00 3350.00 2012 12 601200-001-027--
4 22565448267 650.00 650.00 2012 12 601400-002-027--
5 22565448268 1100.00 1100.00 2012 12 601400-001-027--
I think my COMBINATION of ORDER by (primary key) must be betwwen LedgerDimension ,Year , Month , Display
Any help in this regards
I think what you need to do is:
SUM(BTLine.TransactionCurrencyAmount)
OVER (PARTITION BY BTLine.LedgerDimension ORDER BY YEAR(BTLine.DATE),MONTH(BTLine.DATE),BTLine.LedgerDimension,COMBINATION.DISPLAYVALUE ) AS SUM
let me know if this works.

Need to print highest year and their highest quarter in SQL Server 2012

I have a requirement to print the corresponding highest year and highest quarter for a given column.
Input is in a table:
cityprogram year quarter
=========== ==== =======
Abc 1998 1
Abc 1999 4
Abc 1999 4
Abc 1998 3
xyz 1998 4
xyz 1998 1
xyz 2000 3
It should print
Abc 1999 4
xyz 2000 3
I tried many joins, max conditions, I seem to get quarter 4 and 4 for both of them :( thanks
Use a window function like ROW_NUMBER in a common-table-expression:
WITH CTE AS(
SELECT [cityprogram], [year], [quarter],
RN = ROW_NUMBER() OVER (
PARTITION BY [cityprogram]
ORDER BY [year] DESC, [quarter] DESC)
FROM dbo.TableName
)
SELECT [cityprogram], [year], [quarter]
FROM CTE
WHERE RN = 1
DEMO
CITYPROGRAM YEAR QUARTER
Abc 1999 4
xyz 2000 3
ROW_NUMBER returns only one row per group even if there are ties(cityprograms with the same highest year+quarter). If you then want to show all highest you can replace ROW_NUMBER with DENSE_RANK.

How to get top records of subset?

Say I have a table
StoreID TotalSales Month Year
-- ---------- ----- ----
1 10 1 2012
2 2 1 2012
3 15 1 2012
1 4 2 2012
2 5 2 2012
I need: For each unique "Month/Year", grab the top two StoreID's with the highest Sales.
I'm at a loss on how to do this. I tried with a cross apply but that doesn't seem to work. This is all way over my head so hopefully someone can give me a nudge in the right direction.
This query uses Common Table Expression and Window Function to be able to get all the columns within the row. It works on SQL Server 2005 and up
WITH records
AS
(
SELECT StoreID, TotalSales , Month, Year,
DENSE_RANK() OVER (PARTITION BY Month, Year
ORDER BY TotalSales DESC) rn
FROM tableName
)
SELECT StoreID, TotalSales , Month, Year
FROM records
WHERE rn <= 2
