I have a question about SQL Server.
Table patient:
pn | code | date | doctorcode
---------------------------------------
1 | 10 |2015-02-19 | 100
1 | 10 |2015-02-19 | 101
1 | 10 |2015-02-19 | 102
2 | 10 |2015-02-12 | 101
2 | 10 |2015-02-13 | 102
2 | 10 |2015-02-14 | 103
3 | 10 |2015-02-15 | 103
3 | 10 |2015-02-18 | 104
3 | 10 |2015-02-26 | 105
Table Patientref:
pn | code | sdate | edate | Status
-------------------------------------------------
1 | 10 |2015-02-13 | 2015-02-19 | 1
1 | 10 |2015-02-19 | 2015-03-24 | 2
1 | 10 |2015-04-28 | 2015-05-08 | 4
2 | 10 |2015-02-08 | 2015-02-19 | 4
2 | 10 |2015-02-09 | 2015-02-19 | 2
2 | 10 |2015-02-10 | 2015-02-19 | 2
2 | 10 |2015-02-11 | 2015-02-18 | 1
3 | 10 |2015-02-10 | 2015-02-17 | 4
3 | 10 |2015-02-10 | 2015-02-17 | 3
3 | 10 |2015-02-11 | 2015-02-18 | 3
2 | 10 |2015-04-10 | 2015-05-19 | 2
3 | 10 |2015-02-11 | 2015-02-18 | 1

Here we need consider patient dates that fall between sdate and edate of the patientrefs table, and then we need to consider the highest status values in order (for example, the highest values in order - 2 is first highest, 4 is second highest, 3 is third highest, and 1 is fourth highest value)
If the date falls between multiple different sdate and edate with the same status values, then we need to consider the latest sdate value and from that entire record we need to extract that value.
Examples: patient
pn | code | date | doctorcode
2 | 10 |2015-02-12 | 101
2 | 10 |2015-02-13 | 102
2 | 10 |2015-02-14 | 103
Table : Patientref:
pn | code | sdate | edate | Status
2 | 10 |2015-02-08 | 2015-02-19 | 4
2 | 10 |2015-02-09 | 2015-02-19 | 2
2 | 10 |2015-02-10 | 2015-02-19 | 2
2 | 10 |2015-02-11 | 2015-02-18 | 1
Here, pn=2 values have dates which fall between sdate and edate of patientref table. Then we give highest values status is 2, and status 2 values have two records, then we go for max sdate(latest sdate). Then this pn=2 latest sdates is 2015-02-10 and we need to retrieve the corresponding edate and status values.
Based on this, the desired output is below:
pn | code | date | doctorcode | sdate |edate |status
1 | 10 |2015-02-19 | 100 |2015-02-19 |2015-03-24 | 2
1 | 10 |2015-02-19 | 101 |2015-02-19 |2015-03-24 | 2
1 | 10 |2015-02-19 | 102 |2015-02-19 |2015-03-24 | 2
2 | 10 |2015-02-12 | 101 |2015-02-10 |2015-02-19 | 2
2 | 10 |2015-02-13 | 102 |2015-02-10 |2015-02-19 | 2
2 | 10 |2015-02-14 | 103 |2015-02-10 |2015-02-19 | 2
3 | 10 |2015-02-15 | 103 |2015-02-10 |2015-02-17 | 4
3 | 10 |2015-02-18 | 104 |2015-02-11 |2015-02-18 | 3
3 | 10 |2015-02-26 | 105 |2015-02-26 |2015-03-18 | 1
I tried it like this:
select
a.pn, a.code, a.doctorcode, a.date,
b.sdate, b.edate, b.status
from
patient a
left join
(select
b.pn, b.code, b.sdate, b.edate,
row_number() over (partition by pn, org
order by case when status=2 then 1 when status=4 then 2 when status=3 then 3 when status=1 then 4 end desc,sdate desc) as rn
from patientref) b on a.pn = b.pn and a.code = b.code
and a.rn = 1
and a.date between b.sdate and b.edate
But it does not give the expected result. How can I write the query to achieve this task in SQL Server?
First off, to handle the status sorting you should really have a table in your system showing how they can be sorted. This would just be a table that has the status ID and a sort order column showing sorting priority. However, for your query you can just create a table variable to manage it.
declare #statuses table
([status] int,
sort_order int)
insert into #statuses ([status], sort_order) values (2,0);
insert into #statuses ([status], sort_order) values (4,1);
insert into #statuses ([status], sort_order) values (3,2);
insert into #statuses ([status], sort_order) values (1,3);
Then you can use CROSS APPLY to query your patient table and use the highest priority record from your patientref table:
select
p.pn,
p.code,
p.date,
p.doctorcode,
ca.sdate,
ca.edate,
ca.status
from patient p
cross apply
(select
top 1
pr.pn,
pr.code,
pr.sdate,
pr.edate,
pr.status
from patientref pr
inner join #statuses s on pr.status = s.status
where pr.pn = p.pn
and pr.code = p.code
and p.date between pr.sdate and pr.edate
order by s.sort_order, pr.sdate desc) as ca

I have a Microsoft SQL Server with the following tables:
Projects
BookedHours (with fk_Project = Projects.ID)
Products
ProjectsToProducts (n:m with fk_Projects = Projects.ID and fk_Products = Products.ID)
I now want to select how many hours are booked to which product per month. The problem is, that one project can have multiple products (that's why I need the n:m table).
If I do the following, it will count the hours twice if a project has two products.
SELECT
P.ID AS fk_Product, MONTH(B.Datum) AS Monat, SUM(B.Hours) AS Stunden
FROM
tbl_BookedHours AS B
INNER JOIN
tbl_Projects AS M on B.fk_Project = M.ID
INNER JOIN
tbl_ProjectProduct AS PP ON PP.fk_Project = M.ID
INNER JOIN
tbl_Products AS P ON PP.fk_Product = P.ID
WHERE
YEAR(B.Datum) = 2020
GROUP BY
P.ID, MONTH(B.Datum)
ORDER BY
P.ID, MONTH(B.Datum)
I can get the number of products for each project with this SQL:
SELECT fk_Project, COUNT(*) AS Cnt
FROM tbl_ProjectProduct
GROUP By fk_MainProject
But how can I now divide the hours for each project by its individual factor and add it all up per product and month?
I could do it in my C# program or I could use a cursor and iterate through all projects, but I think there should be an more elegant way.
Edit with sample data:
|----------------| |----------------| |------------------------------|
| tbl_Projects | | tbl_Products | | tbl_ProjectProduct |
|----------------| |----------------| |------------------------------|
| ID | Name | | ID | Name | | ID | fk_Project | fk_Product |
|----+-----------| |----+-----------| |------------------------------|
| 1 | Project 1 | | 1 | Product 1 | | 1 | 1 | 1 |
| 2 | Project 2 | | 2 | Product 2 | | 2 | 1 | 2 |
| 3 | Project 3 | | 3 | Product 3 | | 3 | 2 | 1 |
| 4 | Project 4 | | 4 | Product 4 | | 4 | 3 | 3 |
|----------------| |----------------| | 5 | 4 | 1 |
| 6 | 4 | 2 |
| 7 | 4 | 4 |
|------------------------------|
|--------------------------------------|
| tbl_BookedHours |
|--------------------------------------|
| ID | fk_Project | Hours | Date |
|--------------------------------------|
| 1 | 1 | 10 | 2020-01-15 |
| 2 | 1 | 20 | 2020-01-20 |
| 3 | 2 | 10 | 2020-01-15 |
| 4 | 3 | 30 | 2020-01-18 |
| 5 | 2 | 20 | 2020-01-20 |
| 6 | 4 | 30 | 2020-01-25 |
| 7 | 1 | 10 | 2020-02-15 |
| 8 | 1 | 20 | 2020-02-20 |
| 9 | 2 | 10 | 2020-02-15 |
| 10 | 3 | 30 | 2020-03-18 |
| 11 | 2 | 20 | 2020-03-20 |
| 12 | 4 | 30 | 2020-03-25 |
|--------------------------------------|
The Result should be:
|----------------------------|
| fk_Product | Month | Hours |
|----------------------------|
| 1 | 1 | 55 |
| 2 | 1 | 25 |
| 3 | 1 | 30 |
| 4 | 1 | 10 |
| 1 | 2 | 25 |
| 2 | 2 | 15 |
| 1 | 3 | 30 |
| 2 | 3 | 10 |
| 3 | 3 | 30 |
| 4 | 3 | 10 |
|----------------------------|
For example booking Nr. 1 has to be divided by 2 (because Project 1 has two products) and one half of amount added to Product 1 and the other to Product 2 (Both in January). Booking Nr. 4 should not be divided, because Project 3 only has one product. Booking Numer 12 for example has to be divided by 3.
So that in total the Hours in the end add up to the same total.
I hope it's clearer now.

Consider the following query. I modified your table variables to temp tables so it was easier to debug.
;WITH CTE AS
(
SELECT fk_Project, count(fk_Product) CNT
FROM #tbl_ProjectProduct
GROUP BY fk_Project
)
,CTE2 AS
(
SELECT t1.Date, t2.fk_Project, Hours/CNT NewHours
FROM #tbl_BookedHours t1
INNER JOIN CTE t2 on t1.fk_Project = t2.fk_Project
)
SELECT t4.ID fk_Product, MONTH(date) MN, SUM(NewHours) HRS
FROM CTE2 t1
INNER JOIN #tbl_Projects t2 on t1.fk_Project = t2.id
INNER JOIN #tbl_ProjectProduct t3 on t3.fk_Project = t2.ID
INNER JOIN #tbl_Products t4 on t4.ID = t3.fk_Product
GROUP BY t4.ID,MONTH(date)
The Table data is as below, need to extract records that met the below conditions
Here Value = Value2-Value1
Value of two days back data should be > 2
Value of last day data is < 0
Value of next day data is < 4 and >0
Value of after next day data > 4
All the dates are weekdays,if any date falls on friday, need to compare with next day ie.. Monday. and comparision is with alternative days only

I am pretty much confused at comparing multiple rows, any help is greatly appreciated.
Starting with v2012 we have support for LAG() and LEAD(). Try this out:
SET DATEFORMAT dmy;
DECLARE #tbl TABLE(code INT,[Date] DATE,Value1 INT,Value2 INT);
INSERT INTO #tbl VALUES
(1,'1-1-2018',13,14)
,(1,'2-1-2018',14,18)
,(1,'3-1-2018',15,11)
,(1,'4-1-2018',15,18)
,(1,'5-1-2018',15,18)
,(1,'6-1-2018',11,18)
,(1,'7-1-2018',15,18)
,(2,'1-1-2019', 1, 3)
,(2,'2-1-2018', 2, 5)
,(2,'3-1-2018', 3, 0)
,(2,'4-1-2018', 3, 7)
,(2,'5-1-2018', 3, 4)
,(2,'6-1-2018', 3, 9)
,(2,'7-1-2018', 3, 7);
WITH cte AS
(
SELECT *
,LAG(Value2-Value1,2) OVER(PARTITION BY code ORDER BY [Date]) TwoDaysBack
,LAG(Value2-Value1,1) OVER(PARTITION BY code ORDER BY [Date]) Yesterday
,LEAD(Value2-Value1,1) OVER(PARTITION BY code ORDER BY [Date]) tomorrow
,LEAD(Value2-Value1,2) OVER(PARTITION BY code ORDER BY [Date]) TwoDaysAhead
FROM #tbl
)
SELECT *
FROM cte;
I do not really understand, how you want to use these values in a filter to get the expected output. If you need help with this, just come back...
The result

The idea in short:
Both, LAG() and LEAD() take an argument for the needed value, a second, how many rowswe want to skip, and as a third argument a default value you might specify to avoid NULLs in the result, when there is no row in scope.
The OVER() clause will tell any windowing function if we want to think of the set as divided in groups and the sort order (otherwise the system would not know what is leading or lagging.
With lead and lag window functions:
with cte as (
select *,
lag(value2 - value1, 2) over (partition by code order by date) prev2,
lag(value2 - value1, 1) over (partition by code order by date) prev1,
lead(value2 - value1, 1) over (partition by code order by date) next1,
lead(value2 - value1, 2) over (partition by code order by date) next2
from tablename
)
select code, date, value1, value2
from cte
where prev2 > 2 and prev1 < 0 and next1 > 0 and next1 < 4 and next2 > 4
See the demo.
Results:
code | date | value1 | value2
---: | :------------------ | -----: | -----:
1 | 01/04/2018 00:00:00 | 15 | 18
2 | 01/04/2018 00:00:00 | 3 | 7
There is a difference between your expected results for code = 2 and my results, so check its validity.
This query gives me Event values from 1 to 20 within an hour, how to add to that if a consecutive Event value is >=200 as well?
SELECT ID, count(Event) as numberoftimes
FROM table_name
WHERE Event >=1 and Event <=20
GROUP BY ID, DATEPART(HH, AtHour)
HAVING DATEPART(HH, AtHour) <= 1
ORDER BY ID desc
In this dummy 24h table:
+----+-------+--------+
| ID | Event | AtHour |
+----+-------+--------+
| 1 | 1 | 11:00 |
| 1 | 4 | 11:01 |
| 1 | 1 | 11:02 |

| 1 | 39 | 13:10 |
| 1 | 50 | 13:11 |
| 1 | 2 | 13:12 |
+----+-------+--------+
I would like to select IDs with Event with values with range between 1 and 20 followed immediately by value greater than or equal to 200 within an hour.
Expected result should be something like that:
+----+--------+
| ID | AtHour |
+----+--------+
| 1 | 11 |
| 1 | 13 |
| 2 | 11 |
| 2 | 14 |
| 3 | 09 |
| 3 | 12 |
+----+--------+
or just how many times it has happened for unique ID instead of which hour.
Please excuse me I am still rusty with post formatting!

I want to convert it to tree query in MS-SQL Server 2008 to use it as a Treelist datasource in my win aaplication.
I raised this question before and it's answered with a way that it was very very slow for my big table with more than 5000 records (Create Tree Query From Numeric Mapping Table in SQL). But I think counting "/" and separating AccountID field with "/" can solve my problem easier and very faster.
Anyway, My expected result must be like below:
AccountID AccountName ID ParentID Level HasChild

Please Help Me.
I modified my answer given in the first question...
It would be best, if your table would keep the relation data directly in indexed columns. Before you change your table's structure you might try this:
A table with test data
DECLARE #tbl TABLE ( AccountID VARCHAR(100), AccountName VARCHAR(100));
INSERT INTO #tbl VALUES
('11','Acc11')
,('12','Acc12')
,('13','Acc13')
,('11/11','Acc11/11')
,('11/12','Acc11/12')
,('11/111','Acc11/111')
,('11/11/001','Acc11/11/001')
,('11/11/002','Acc11/11/002')
,('12/111','Acc12/111')
,('12/112','Acc12/112');
This will get the needed data into a newly created temp table called #tempHierarchy
SELECT AccountID
,AccountName
,ROW_NUMBER() OVER(ORDER BY LEN(AccountID)-LEN(REPLACE(AccountID,'/','')),AccountID) AS ID
,Extended.HierarchyLevel
,STUFF(
(
SELECT '/' + A.B.value('.','varchar(10)')
FROM Extended.IDsXML.nodes('/x[position() <= sql:column("HierarchyLevel")]') AS A(B)
FOR XML PATH('')
),1,2,'') AS ParentPath
,Extended.IDsXML.value('/x[sql:column("HierarchyLevel")+1][1]','varchar(10)') AS ownID
,Extended.IDsXML.value('/x[sql:column("HierarchyLevel")][1]','varchar(10)') AS ancestorID
INTO #tempHierarchy
FROM #tbl
CROSS APPLY(SELECT LEN(AccountID)-LEN(REPLACE(AccountID,'/','')) + 1 AS HierarchyLevel
,CAST('<x></x><x>' + REPLACE(AccountID,'/','</x><x>') + '</x>' AS XML) AS IDsXML) AS Extended
;
The intermediate result
+-----------+--------------+----+----------------+------------+-------+------------+
| AccountID | AccountName | ID | HierarchyLevel | ParentPath | ownID | ancestorID |
+-----------+--------------+----+----------------+------------+-------+------------+
| 11 | Acc11 | 1 | 1 | | 11 | |

And now a similar recursive approach takes place as in my first answer. But - as it is using a real table now and all the string splitting has taken place already - it should be faster...
WITH RecursiveCTE AS
(
SELECT th.*
,CAST(NULL AS BIGINT) AS ParentID
,CASE WHEN EXISTS(SELECT 1 FROM #tempHierarchy AS x WHERE x.ParentPath=th.AccountID) THEN 1 ELSE 0 END AS HasChild
FROM #tempHierarchy AS th WHERE th.HierarchyLevel=1
UNION ALL
SELECT sa.AccountID
,sa.AccountName
,sa.ID
,sa.HierarchyLevel
,sa.ParentPath
,sa.ownID
,sa.ancestorID
,(SELECT x.ID FROM #tempHierarchy AS x WHERE x.AccountID=sa.ParentPath)
,CASE WHEN EXISTS(SELECT 1 FROM #tempHierarchy AS x WHERE x.ParentPath=sa.AccountID) THEN 1 ELSE 0 END AS HasChild
FROM RecursiveCTE AS r
INNER JOIN #tempHierarchy AS sa ON sa.HierarchyLevel=r.HierarchyLevel+1
AND r.AccountID=sa.ParentPath
)
SELECT r.AccountID
,r.AccountName
,r.ID
,r.ParentID
,r.HierarchyLevel
,r.HasChild
FROM RecursiveCTE AS r
ORDER BY HierarchyLevel,ParentID;
And finally I clean up
DROP TABLE #tempHierarchy;
And here's the final result
+-----------+--------------+----+----------+----------------+----------+
| AccountID | AccountName | ID | ParentID | HierarchyLevel | HasChild |
+-----------+--------------+----+----------+----------------+----------+
| 11 | Acc11 | 1 | NULL | 1 | 1 |
+-----------+--------------+----+----------+----------------+----------+
| 12 | Acc12 | 2 | NULL | 1 | 1 |
+-----------+--------------+----+----------+----------------+----------+
| 13 | Acc13 | 3 | NULL | 1 | 0 |
+-----------+--------------+----+----------+----------------+----------+
| 11/11 | Acc11/11 | 4 | 1 | 2 | 1 |
+-----------+--------------+----+----------+----------------+----------+
| 11/111 | Acc11/111 | 5 | 1 | 2 | 0 |
+-----------+--------------+----+----------+----------------+----------+
| 11/12 | Acc11/12 | 6 | 1 | 2 | 0 |
+-----------+--------------+----+----------+----------------+----------+
| 12/111 | Acc12/111 | 7 | 2 | 2 | 0 |
+-----------+--------------+----+----------+----------------+----------+
| 12/112 | Acc12/112 | 8 | 2 | 2 | 0 |
+-----------+--------------+----+----------+----------------+----------+
| 11/11/001 | Acc11/11/001 | 9 | 4 | 3 | 0 |
+-----------+--------------+----+----------+----------------+----------+
| 11/11/002 | Acc11/11/002 | 10 | 4 | 3 | 0 |

I am new to SQL and have the following issue I would like to solve. The table I would like to edit looks like this:
ID | ShopID | ProductID | PurchasePrice
1 | 1 | 111 | 1,00
2 | 2 | 111 | 1,40
3 | 3 | 111 | 1,30
4 | 1 | 222 | 2,00
5 | 2 | 222 | 2,50
6 | 3 | 222 | 2,90
7 | 1 | 333 | 3,00
8 | 2 | 333 | 3,80
9 | 3 | 333 | 3,90
ID (unique)
ShopID (3 different values, representing 3 different shops)
ProductID (refers to unique id of different table where more common product info is stored) the same value is available three times for every different ShopID
PurchasePrice (over time shops 2 and 3 have edited their pricing, it's a mess now)
The Value of PurchasePrice for ShopID 2 and 3 should be 10% higher than the PurchasePrice for ShopID 1 where ProductID is the same. How can I easily do this in SQL server 2008?
The table should look like this:
ID | ShopID | ProductID | PurchasePrice
1 | 1 | 111 | 1,00
2 | 2 | 111 | 1,10
3 | 3 | 111 | 1,10
4 | 1 | 222 | 2,00
5 | 2 | 222 | 2,20
6 | 3 | 222 | 2,20
7 | 1 | 333 | 3,00
8 | 2 | 333 | 3,30
9 | 3 | 333 | 3,30
UPDATE t
SET t.PurchasePrice = p.PurchasePrice*1,10
FROM Table t
LEFT JOIN (
SELECT ProductID,PurchasePrice FROM Table WHERE ShopID=1) p ON t.ProductID = p.ProductID
WHERE t.ShopID<>1
Here we get the list of prices in Shop 1 (See the left join query) and update prices of shops other than 1 to shop 1's ProductPrice * 1,10
