I have table like below,
Txn_Id Txn_Type
___________________
1 101
1 102
1 103
1 104
2 101
2 102
2 104
3 101
3 104
I want rows which has only txn_type 101 and 104. For eg., I should get only Txn_Id "3" for above data.
I tried like below and getting result. Is it possible to have single query to achive this.
Select txn_id from Txn where txn_id in (Select txn_id from Txn where txn_id = 101) and txn_id =104.
Select txn_id from Txn where txn_type in (101,104)
option 2
Select txn_id from Txn where (txn_type = 101 OR txn_type=104)
To get only "3"
Select distinct txn_id from Txn t1 where (txn_type = 101 OR txn_type=104)
and not exists(
select 1 from Txn t2 where t2.txn_type IN (102,103) and t2.txn_id = t1.txn_id
)
Hi As per your above comments you only need the txn_id =3(max)
Please Find the code below.
DECLARE #Table1 TABLE
(txn_id int, Txn_Type int)
;
INSERT INTO #Table1
(txn_id , Txn_Type )
VALUES
(1, 101),
(1, 102),
(1, 103),
(1, 104),
(2, 101),
(2, 102),
(2, 104),
(3, 101),
(3, 104)
;
Select max(txn_id ),Txn_Type
from #Table1 where item in (101,104)
group by Txn_Type
As balaji pointed out, #Ayush solution is not flexible, since will return incorrect results if you, for example, add another pair of records in the table (4,101) and (4,104). IMO, you have to join table to itself for some filtering, something like this:
DECLARE #Table1 TABLE
(txn_id int, Txn_Type int);
INSERT INTO #Table1
(txn_id , Txn_Type )
VALUES
(1, 101),
(1, 102),
(1, 103),
(1, 104),
(2, 101),
(2, 102),
(2, 104),
(3, 101),
(3, 104),
(4, 101),
(4, 104);
select t1.*
from #Table1 t1
inner join (select txn_id, count(*) as total
from #Table1
group by Txn_id
having count(*) < 3
) t2 on t2.txn_id = t1.txn_id
where t1.Txn_Type in (101,104)

I am using T-SQL for a few months and there is one thing I simply don't know how to do. Let's say we have a table created below
DECLARE #table TABLE
(
id int,
status_FK int,
[value] int
)
INSERT INTO #table (id, status_FK, [value])
VALUES (1, 1, 1000),
(2, 1, 2000),
(3, 2, 3000),
(4, 1, 2000),
(5, 2, 2000),
(6, 2, 3000),
(7, 5, 12000)
SELECT
(SELECT SUM(value) WHERE status_FK = 1) AS 'status1',
(SELECT SUM(value) WHERE status_FK = 2) AS 'status2'
FROM
#table
WHERE
value > 1500
What I'm trying to do is use condition value > 1500 for all subqueries but also each subquery have specific condition. Can someone please explain me how to do this simple thing without repeating whole main query in both subqueries with different conditions? Many thanks <3
Probably something like that:
SELECT
SUM(case when status_FK = 1 then value else 0 end) as `status1`,
SUM(case when status_FK = 2 then value else 0 end) as `status2`
FROM #table
WHERE value > 1500
Update 1:
You can have many as you like, best if you have small of column to display:
SELECT
SUM(case when status_FK = 1 then value else 0 end) as `status1`,
SUM(case when status_FK = 2 then value else 0 end) as `status2`,
...
SUM(case when status_FK = n then value else 0 end) as `statusn`,
FROM #table
WHERE value > 1500
For complex cases you can look at PIVOT.
You can try using Join also
SELECT Status_fk
,sum(value)
FROM #table t
INNER JOIN (
VALUES (1)
,(2)
) X(StatusID) ON t.status_FK = X.StatusID
WHERE value > 1500
GROUP BY status_FK
You can use PIVOT, a powerful operator.
CREATE TABLE #TEMP
(
id int,
status_FK int,
[value] int
)
INSERT INTO #TEMP (id, status_FK, [value])
VALUES (1, 1, 1000),
(2, 1, 2000),
(3, 2, 3000),
(4, 1, 2000),
(5, 2, 2000),
(6, 2, 3000),
(7, 5, 12000)
SELECT [1] AS status1, [2] AS status2
FROM (SELECT status_FK, value FROM #TEMP WHERE value > 1500) AS T
PIVOT(SUM([value]) FOR status_FK IN ([1], [2])) AS PT

I need to fetch all the orders with the customer detail and the customer address on the order date.
SELECT T1.ORDERNo, T1.ORDERDATE, T1.CUSTOMER, T2.NAME, T3.STATE
FROM SALESORDER T1, CUSTOMER T2, CUSTOMERADDRESS T3
RIGHT JOIN(
SELECT CUSTOMER, MAX(EFFECTIVEDATE) FROM CUSTOMERADDRESS
--WHERE EFFECTIVEDATE <= T1.ORDERDATE
GROUP BY CUSTOMER)T4
ON T3.CUSTOMER = T4.CUSTOMER AND T3.EFFECTIVEDATE=T4.EFFECTIVEDATE
WHERE T1.CUSTOMER = T2.CUSTOMERNUMBER
AND T1.CUSTOMER = T3.CUSTOMERNUMBER
Want to see how to do compare in the join where i compare first table to the 3rd table in the join. see the commented code --WHERE EFFECTIVEDATE <= T1.ORDERDATE
If I remove the commented code, the table in the join cannot reference a table outside.
The expected output is:

The problem: Need to Pick all the Sales Orders and their customer Name, and the Customer Address. The important and tricky part is the customer address changes based on the date of the sales order.

ParentId
So, an infinite amount of Categories can be the child of a category. Take for example the following hierarchy:

Recursive cte to the rescue....
Create and populate sample table (Please save us this step in your future questions):
DECLARE #T as table
(
id int,
name varchar(100),
parent_id int
)
INSERT INTO #T VALUES
(1, 'A', NULL),
(2, 'A.1', 1),
(3, 'A.2', 1),
(4, 'A.1.1', 2),
(5, 'B', NULL),
(6, 'B.1', 5),
(7, 'B.1.1', 6),
(8, 'B.2', 5),
(9, 'A.1.1.1', 4),
(10, 'A.1.1.2', 4)
The cte:
;WITH CTE AS
(
SELECT id, name, name as path, parent_id
FROM #T
WHERE parent_id IS NULL
UNION ALL
SELECT t.id, t.name, cast(cte.path +','+ t.name as varchar(100)), t.parent_id
FROM #T t
INNER JOIN CTE ON t.parent_id = CTE.id

The query:
SELECT id, name, path
FROM CTE

'29/03/2018 07:15' is nvarchar-type, you need datetime.
nvarchar convert to datetime: SELECT CONVERT(datetime, '29/03/2018 07:15', 103)

On this SQL Server 2008 database I have a table of attendance, students come into school every day and check in, the table looks something like this:
SchoolID | StudentID | Date
There will be a record for every day for every student on this table. What I want to find out is, given a start date, an end date, and a number of days (gap), find any student that has not checked into school for that number of days. So for example, I need to know which students missed 3 days straight during the month of December, and spit out the list of StudentIDs.
How can I accomplish something like that?
You can produce date ranges from startdate to enddate
then outer join this data with your table, if the student wouldn't have come consider it as 1 then summarize this data.
for generating date range you can use this function as below
CREATE FUNCTION [dbo].[DateRange]
(
#Increment CHAR(1),
#StartDate DATETIME,
#EndDate DATETIME
)
RETURNS
#SelectedRange TABLE
(IndividualDate DATETIME)
AS
BEGIN
;WITH cteRange (DateRange) AS (
SELECT #StartDate
UNION ALL
SELECT
CASE
WHEN #Increment = 'd' THEN DATEADD(dd, 1, DateRange)
WHEN #Increment = 'w' THEN DATEADD(ww, 1, DateRange)
WHEN #Increment = 'm' THEN DATEADD(mm, 1, DateRange)
END
FROM cteRange
WHERE DateRange <=
CASE
WHEN #Increment = 'd' THEN DATEADD(dd, -1, #EndDate)
WHEN #Increment = 'w' THEN DATEADD(ww, -1, #EndDate)
WHEN #Increment = 'm' THEN DATEADD(mm, -1, #EndDate)
END)
INSERT INTO #SelectedRange (IndividualDate)
SELECT DateRange
FROM cteRange
OPTION (MAXRECURSION 3660);
RETURN
END
GO
then
select sum(isAbsent) absentDays, s.studentid from
(
select case when studentid is null then 1 else 0 end isAbsent,individualDate,s.studentid from DateRange('d', '01/11/2014', '30/11/2014') d
cross join tblstudent s
left outer join yourtable on yourtable.Date = d.IndividualDate and yourtable.studentid = s.studentid
) x
group by s.studentid
having sum(isAbsent) > 3
Just look at this. I think you will be able to figure out you own answer from that.This solution take care of the weekend days and holidays :
