With the following query ...
select aa.trip_id, aa.arrival_time, aa.departure_time, aa.stop_sequence, aa.stop_id, bb.stop_name
from OeBB_Stop_Times aa
left join OeBB_Stops bb on aa.stop_id = bb.stop_id
I get the following table:
Now I want the first and last line/value from the column stop_sequence referring to column trip_id, so the result should be:
How can I do that?
Thanks
You can do a sub-query to get the min and max and join against that data.
Like this:
select aa.trip_id, aa.arrival_time, aa.departure_time, aa.stop_sequence, aa.stop_id, bb.stop_name
from OeBB_Stop_Times aa
join (
SELECT trip_id, max(stop_sequence) as max_stop, min(stop_sequence) as min_stop
FROM OeBB_Stop_Times
GROUP BY trip_di
) sub on aa.trip_id = sub.trip_id AND (aa.stop_sequence = sub.max_stop or aa.stop_sequence = sub.min_stop)
left join OeBB_Stops bb on aa.stop_id = bb.stop_id
You can use the ROW_NUMBER() window function twice to filter out rows, as in:
select *
from (
select *,
row_number() over(partition by trip_id order by arrival_time) as rn,
row_number() over(partition by trip_id order by arrival_time desc) as rnr
from OeBB_Stop_Times
) x
where rn = 1 or rnr = 1
order by trip_id, arrival_time
You can use row_number():
select s.*
from (select st.trip_id, st.arrival_time, st.departure_time,
st.stop_sequence, st.stop_id, s.stop_name,
row_number() over (partition by st.trip_id order by st.stop_sequence) as seqnum_asc,
row_number() over (partition by st.trip_id order by st.stop_sequence desc) as seqnum_desc
from OeBB_Stop_Times st left join
OeBB_Stops s
on st.stop_id = s.stop_id
) s
where 1 in (seqnum_asc, seqnum_desc);
Note that I fixed the table aliases so they are meaningful rather than arbitrary letters.
Actually, if the stop_sequence is guaranteed to start at 1, this is a bit simpler:
select s.*
from (select st.trip_id, st.arrival_time, st.departure_time,
st.stop_sequence, st.stop_id, s.stop_name,
max(stop_sequence) over (partition by st.trip_id) as max_stop_sequence
from OeBB_Stop_Times st left join
OeBB_Stops s
on st.stop_id = s.stop_id
) s
where stop_sequence in (1, max_stop_sequence);

I a SQL with a row_number() function, and I would like to join on additional tables to get the fields below. How would I accomplish this?
Desired fields:
EMPLOYEE.EMPLID
EMPLOYEE.JOBTITLE
NAME.FIRST_NAME
NAME.LAST_NAME
LOCATION.ADDRESS
PROFESSIONAL_NAME.PROF_NAME
Beginning SQL:
SELECT COUNT(*)
FROM
(
SELECT EMPLOYEE.*, ROW_NUMBER() OVER (PARTITION BY EMPLID ORDER BY
PRIM_ROLE_IND DESC, EMPL_RCD ASC) as RN
FROM EMPLOYEE
WHERE JOB_INDICATOR = 'P'
) dt
WHERE RN = 1
When I try to add a left join at the end, I get an error that says "EMPLOYEE"."EMLID" invalid identifier.
What I'm trying:
SELECT
EMPLOYEE.EMPLID,
EMPLOYEE.JOBTITLE,
NAME.FIRST_NAME,
NAME.LAST_NAME,
LOCATION.ADDRESS,
PROFESSIONAL_NAME.PROF_NAME
FROM
(
SELECT EMPLOYEE.*, ROW_NUMBER() OVER (PARTITION BY EMPLID ORDER BY
PRIM_ROLE_IND DESC, EMPL_RCD ASC) as RN
FROM EMPLOYEE
WHERE JOB_INDICATOR = 'P'
)
LEFT JOIN NAME ON EMPLOYEE.EMPLID = NAME.EMPLID
WHERE
RN = 1
AND
NAME.EFFDT = (
SELECT
MAX (NAME2.EFFDT)
FROM
NAME NAME2
WHERE
NAME2.EMPLID = NAME.EMPLID
AND NAME.NAME_TYPE = 'PRI'
)
AND EMPLOYEE.JOB_INDICATOR = 'P'
You just need to alias your table
...
(
SELECT EMPLOYEE.*, ROW_NUMBER() OVER (PARTITION BY EMPLID ORDER BY
PRIM_ROLE_IND DESC, EMPL_RCD ASC) as RN
FROM EMPLOYEE
WHERE JOB_INDICATOR = 'P'
) temp_employee --add this
LEFT JOIN NAME ON temp_employee.EMPLID = NAME.EMPLID
...
When you create your new table with row_number() in an inner select you essentially create a new table. You need to alias or name this table and then refer to that alias. In the above your from is the inner select, not the EMPLOYEE table. See below for simplified example.
select newtable.field from (select field from mytable) newtable
I have the following data that is returned to me. I need to get a distinct or max sum of all the commission by taxid for a single repnbr. The 'qtrlycommrep' column is the value I'm trying to get to, but not able to. For repnbr c590, I need to get the 854.66 commission amount, which is the max for each taxid.
What am I doing wrong?
Any help would be much appreciated!
Here's what I've tried so far. Using the Row_number
select distinct
sub.Repnbr
, (sub.QtrLYComm) as qtrlycommrep
from (
select distinct repnbr, QtrLYComm
, rn = row_number() over(partition by repnbr order by QtrLYComm desc)
from #qtrly
) sub
where sub.rn = 1
Cross Apply
select distinct
#qtrly.repnbr
, x.QtrLYComm as qtrlycommrep
from #qtrly
cross apply (
select top 1
*
from #qtrly as i
where i.repnbr = Repnbr
order by i.qtrlycomm desc
) as x;
inner join
select
#qtrly.repnbr, #qtrly.qtrlycomm as qtrlycommrep
from #qtrly
inner join (
select maxvalue = max(qtrlycomm), repnbr
from #qtrly
group by repnbr
) as m
on #qtrly.repnbr = m.repnbr
and #qtrly.qtrlycomm = m.maxvalue;
order by row_number
select top 1 with ties
#qtrly.repnbr, #qtrly.qtrlycomm as qtrlycommrep
from #qtrly
order by
row_number() over(partition by repnbr
order by qtrlycomm desc)
You want one value per tax id. You need to include that. For instance:
select q.Repnbr, sum(q.QtrLYComm) as qtrlycommrep
from (select q.*,
row_number() over(partition by repnbr, taxid order by QtrLYComm desc) as seqnum
from #qtrly q
) q
where seqnum = 1
group by q.Repnbr;
However, I would be inclined to use two levels of aggregation:
select q.Repnbr, sum(q.QtrLYComm) as qtrlycommrep
from (select distinct repnbr, taxid, QtrLYComm
from #qtrly q
) q
group by q.Repnbr;
I have the following table:
I want to get the most recent status for each dept_code that a CL_ID has. So the desired output would be this:
I have tried the following but this give me just the most recent status for each client and not each of their dept_codes.
SELECT *
FROM [CIMSHR6_MERGED].[dbo].[C3CLSTAT] C
INNER JOIN
(SELECT CLIENT_NUMBER, MAX(STATUS_DATE) AS SDATE
FROM [CIMSHR6_MERGED].[dbo].[C3CLSTAT]
GROUP BY CLIENT_NUMBER) X
ON X.CLIENT_NUMBER = C.CLIENT_NUMBER
AND X.SDATE = C.STATUS_DATE
ORDER BY C.CLIENT_NUMBER
Any help would be much appreciated. Thanks.
A convenient method that works in SQL Server is:
select top (1) cl.*
from [CIMSHR6_MERGED].[dbo].[C3CLSTAT] cl
order by row_number() over (partition by cl_id, dept_code order by status_date desc);
A method that is efficient with the right indexes in almost any database is:
select cl.*
from [CIMSHR6_MERGED].[dbo].[C3CLSTAT] cl
where cl.status_date = (select max(cl2.status_date)
from [CIMSHR6_MERGED].[dbo].[C3CLSTAT] cl2
where cl2.cl_id = cl.cl_id and cl2.dept_code = cl.dept_code
);
The right index is on (cl_id, dept_code, status_date).
I would also use ROW_NUMBER, but with a subquery:
SELECT CL_ID, Status_date, Status, Dept_code
FROM
(
SELECT *,
ROW_NUMBER() OVER (PARTITION BY CL_ID, Dept_code ORDER BY Status_date DESC) rn
FROM CIMSHR6_MERGED].[dbo].[C3CLSTAT]
) t
WHERE rn = 1;
1) Firstly group everything on Dept_Code,CL_ID and assign rank for each row with in the group in descending order.
2) Select all the rows with rnk=1 which would display your desired result.
SELECT Z.CL_ID,
Z.Status_Date,
Z.Status,
Z.Dept_Code
FROM
(
SELECT *,
RANK() OVER( PARTITION BY Dept_Code,CL_ID, ORDER BY Status_Date DESC ) AS rnk
FROM [CIMSHR6_MERGED].[dbo].[C3CLSTAT]
) Z
WHERE Z.rnk = 1;
This would work for almost all databases
select * from c3clstat c
where exists
(select 1 from c3clstat c1
where c1.cl_id=c.cl_id
and c1.dept_code=c.dept_code
group by cl_id,dept_code
having c.status_date=max(c1.status_date)
)
I've got a question about a sql result and how to achieve the following.
In the Screenshot, there is a Rownumber for every ID, and every ID has another column which has a status 'old' or 'processed'. What i want is, if the RN is = 1 and the Status is processed, than all other RN of this ID should also have the status 'processed'.
Is there a possibility to achieve this in sql?
SELECT RN = ROW_NUMBER() OVER (PARTITION BY [NODE_NAME]
ORDER by REPORTING_RELEVANT_STATUS_ID DESC, BILLING_PERIOD DESC)
,[CI_EQUIPMENT_ID] AS ID_PART
,[REPORTING_RELEVANT_STATUS_ID] AS REPORTING_RELEVANT
,[BILLING_PERIOD]
, [NODE_NAME]
FROM Table
Put your query in CTE? then JOIN it with actual table:
;WITH cte AS (
SELECT RN = ROW_NUMBER() OVER (PARTITION BY [NODE_NAME]
ORDER by REPORTING_RELEVANT_STATUS_ID DESC, BILLING_PERIOD DESC)
,[CI_EQUIPMENT_ID] AS ID_PART
,[REPORTING_RELEVANT_STATUS_ID] AS REPORTING_RELEVANT
,[BILLING_PERIOD]
, [NODE_NAME]
FROM Table
)
SELECT t.[CI_EQUIPMENT_ID] AS ID_PART,
CASE WHEN c.RN is NOT NULL THEN c.REPORTING_RELEVANT ELSE t.[REPORTING_RELEVANT_STATUS_ID] END AS REPORTING_RELEVANT,
t.[BILLING_PERIOD],
t.[NODE_NAME]
FROM Table t
LEFT JOIN (
SELECT *
FROM cte
WHERE RN = 1 AND REPORTING_RELEVANT = 'PROCESSED'
) as c
ON c.ID_PART = t.[CI_EQUIPMENT_ID]
Creating common table expression
Updating the CTE values based on RN=1 and Status=Processed. using the Self Join
here:
;with CTE (RN,ID_PART,REPORTING_RELEVANT,BILLING_PERIOD,NODE_NAME) AS
(
SELECT RN = ROW_NUMBER() OVER (PARTITION BY [NODE_NAME]
ORDER by REPORTING_RELEVANT_STATUS_ID DESC, BILLING_PERIOD DESC)
,[CI_EQUIPMENT_ID] AS ID_PART
,[REPORTING_RELEVANT_STATUS_ID] AS REPORTING_RELEVANT
,[BILLING_PERIOD]
, [NODE_NAME]
FROM Table
)
Update CTE1
set CTE1.Status='Processed'
from CTE CTE1 inner join CTE CTE2
on CTE1.ID_PART=CTE2.ID_PART
where CTE2.RN=1 and CTE2.Status='Processed'
I have two table in sql. First one the patient list, second one is their report. all patient's reports are in the report, just with id we can join them. Each patient has some reports (Maybe all the fields of a record is not filled). Now I want to make a report that get the last report of each patient but if some field are empty in the last record of that patient I should fill it with last filled record of that patients records. I have date in the table of reports.
I want to do it for all patients. Here I will add a pic for one patient as an example
In the example above, I want just highlighted ones for this patient in the report.
I have write this query but it give even when a filed in the last record is null while it has data in previous records.

this is a sample,
in your case you have to get the value of each column in a subquery (either in the join statement, or in the main select statement
example:
inner join (
select distinct bartar_patientname
,(select top 1 bartar_pastePerMonth from [Bartar_MSCRM].[dbo].[Filteredbartar_callcenterreport] c2 where c2.bartar_patientname = cte.bartar_patientname and c2.bartar_pastePerMonth is not null order by c2.bartar_date desc) as bartar_date
,(select top 1 bartar_acc from [Bartar_MSCRM].[dbo].[Filteredbartar_callcenterreport] c2 where c2.bartar_patientname = cte.bartar_patientname and c2.bartar_acc is not null order by c2.bartar_date desc) as bartar_acc
,(select top 1 bartar_insuranceinfo from [Bartar_MSCRM].[dbo].[Filteredbartar_callcenterreport] c2 where c2.bartar_patientname = cte.bartar_patientname and c2.bartar_insuranceinfo is not null order by c2.bartar_date desc) as bartar_insuranceinfo
,(select top 1 bartar_brand from [Bartar_MSCRM].[dbo].[Filteredbartar_callcenterreport] c2 where c2.bartar_patientname = cte.bartar_patientname and c2.bartar_brand is not null order by c2.bartar_date desc) as bartar_brand
from [Bartar_MSCRM].[dbo].[Filteredbartar_callcenterreport] cte
) r
Again, this is a sample of the solution.
Your script is fine as it looks, so I'll just place that on a temporary table for now, and do a per sequence query and filter it by "OR" afterwards.
Please try the script below.
