I have a view which results the following rows.
comp Sub-comp Lognum id Firname LAstname
AK AK-G 0 3897 ABC DEF
AK AK-G 0 5432 mark ray
MC MC-A 0 1234 john steve
MC MC-A 0 5678 dan pitcher
MC MC-A 0 9843 james robin
MC MC-A 84 1234 john steve
MC MC-A 84 5678 dan pitcher
MC MC-A 84 9843 james robin
I want to fetch the only the rows that has a lognum (if the same row has 0 also as lognum) along with the other rows that has just 0 as lognum.
The result table should be like this
comp Sub-comp Lognum id Firname LAstname
AK AK-G 0 3897 ABC DEF
AK AK-G 0 5432 mark ray
MC MC-A 84 1234 john steve
MC MC-A 84 5678 dan pitcher
MC MC-A 84 9843 james robin
And the outline of the query is as follows
create view view1 as
select
comp, Sub-comp, "00" as Lognum, id ,Firname ,LAstname
from
table A
inner joins---
UNION
select
select
comp, Sub-comp, Lognum, id ,Firname ,LAstname from
table B
inner joins----
;
Can anyone help?
Thanks!
Try this:
select * from(
select comp,
Sub-comp,
Lognum,
id,
Firname,
LAstname,
row_number() over(partition by id order by lognum desc) rn
from table_name)
where rn = 1;
This will show the line with the biggest lognum grouped by the ID.
This query should work, even in cases where, for a given id value, you have multiple "non-zero" lognum rows.
If you look at the where clause, rows with non-zero lognum values are always returned (t.Lognum != 0). But rows with zero lognum values will also return, but only if the t.rn = 1 condition is true, which will only happen if there aren't any other non-zero lognums for that same id (see the order by clause of the row_number() window function).
select t.comp,
t.Sub-comp,
t.Lognum,
t.id,
t.Firname,
t.LAstname
from (select t.*,
row_number() over (
partition by t.id
order by case when t.lognum = 0 then 1 else 0 end) as rn
from your_view t) t
where t.Lognum != 0 or t.rn = 1

I've been tasked with returning only rows with unique IDs but returning a row for every ID in SQL. How would I go about this?
Logic:
For primary row, select where JOB_INDICATOR = ‘P’. If there are multiple rows, then use the record where PRIM_ROLE_IND = ‘Y’. If there are still multiple then select the lowest numbered EMPL_RCD starting at 0.
Example starting point:
id
name
job
job_indicator
prim_role_ind
empl_rcd
1001
John Doe
Director
P
N
0
1001
John Doe
Professor
P
Y

1001
John Doe

Desired return:

So far, I have the below, but a new requirement was added to do conditional components.
SELECT *
FROM EMPLOYEE
WHERE JOB_INDICATOR = 'P'
You can use window function ROW_NUMBER() to accomplish this:
SELECT *
FROM
(
SELECT EMPLOYEE.*, ROW_NUMBER() OVER (PARTITION BY id ORDER BY
prim_role_ind DESC, empl_rcd ASC) as rn
FROM EMPLOYEE
WHERE JOB_INDICATOR = 'P'
) dt
WHERE rn = 1
I have the following table:
dbo.split
Name Time
Alex 120
John 80
John 300
Mary 500
Bob 900
And then another table dbo.travel
Name Time
Alex 150
Alex 160
Alex 170
John 90
John 100
John 310
Mary 550
Mary 600
Mary 499
Bob 800
Bob 700
For each value in table split I need to find the next value in table travel. I tried to do it with CTE a with ROW_NUMBER() to get next by group, but there's no way I can group by correct value, since dbo.split can containt multiple values for the same name.
I'm looking for the following output:
Name Time TravelTime
Alex 120 150
John 80 90
John 300 310
Mary 500 550
Bob 900 NULL
Here's what I have so far but it fails because split table can have multiple records per person:
;with result as (
select t.*,
ROW_NUMBER() OVER (Partition BY t.Name order by t.Time) as rn
from travel t join split s
on t.Name = s.Name and t.TIME>s.Time
)
I would use apply:
select s.*, t.time
from split s outer apply
(select top (1) t.*
from travel t
where t.name = s.name and t.time > s.time
order by t.time asc
) t;
In this case, apply is doing essentially the same thing as a correlated subquery, so you could phrase it that way as well.
You can try as below
Select * from(Select
Name,t.time,t1.time,
Row_number() over (partition by
Name,t.time order by t1.time) rn
from split t
Join travel t1 on t.time <t1.time and
t.name =t1.name)
where
rn=1;
I am trying to extract only single row after name = system in each case where the town is not Austin.
In case 1001 there are 8 rows, row # 4 is system, output should be only the row with Name=Terry and Date Moved=7/4/2019 (Next entry with town /= Austin)
Case Name Town Date Moved Row #(Not in table)
1001 Ted Madisson 9/7/2018 1
1001 Joyal Boston 10/4/2018 2
1001 Beatrice Chicago 1/1/2019 3
1001 System Chicago 1/5/2019 4
1001 John Austin 4/11/2019 5
1001 Simon Austin 6/11/2019 6
1001 Terry Cleveland 7/4/2019 7
1001 Hawkins Newyork 8/4/2019 8
1002 Devon Boston 12/4/2018 1
1002 Joy Austin 12/7/2018 2
1002 Rachael Newyork 12/19/2018 3
1002 Bill Chicago 1/4/2019 4
1002 System Dallas 2/12/2019 5
1002 Phil Austin 3/16/2019 6
1002 Dan Seattle 5/18/2019 7
1002 Claire Birmingham 7/7/2019 8
Tried sub query with row number function and not in ('Austin') filter
ROW_NUMBER() OVER(PARTITION BY Case ORDER BY Moved_date ASC) AS ROWNUM
Please note there are > 10k cases.
You can try this below script-
WITH CTE AS
(
SELECT [Case],[Name],Town,[Date Moved],
ROW_NUMBER() OVER (PARTITION BY [Case] ORDER BY [Date Moved]) [Row #]
FROM your_table
)
SELECT A.*
FROM CTE A
INNER JOIN
(
SELECT C.[Case],C.Town,MAX(C.[Row #]) MRN
FROM CTE C
INNER JOIN
(
SELECT *
FROM CTE A
WHERE A.Name = 'System'
)D ON C.[Case] = D.[Case] AND C.[Row #] > D.[Row #]
AND C.Town = 'Austin'
GROUP BY C.[Case],C.Town
)B ON A.[Case] = B.[Case] AND A.[Row #] = B.MRN+1
Output is -
Case Name Town Date Moved Row #
1001 Terry Cleveland 7/4/2019 6
1002 Dan Seattle 5/18/2019 7
Here are three possibilities. I'm still concerned about ties though. The first one will return multiple rows while the others only one per case:
with matches as (
select t1."case", min(t2."Date Moved") as "Date Moved"
from Movements r1 inner join Movements t2 on t1."case" = t2."case"
where t1.name = 'System' and t2.Town <> 'Austin'
and t2."Date Moved" > t1."Date Moved"
group by t1."case"
)
select t.*
from Movements t inner join matches m
on m."case" = t."case" and m."Date Moved" = t."Date Moved";
select m2.*
from Movements m1 cross apply (
select top 1 * from Movements m2
where m2.Town <> 'Austin' and m2."Date Moved" > m1."Date Moved"
order by m2."Date Moved"
) as match
where m1.name = 'System';
with m1 as (
select *,
count(case when name = 'System') over (partition by "case" order by "Date Moved") as flag
from Movements
), m2 as (
select *,
row_number() over (partition by "case" order by "Date Moved") as rn
from m1
where flag = 1 and name <> 'System' and Town <> 'Austin'
)
select * from m2 where rn = 1;
I'm basically assuming this is SQL Server. You might need a few minor tweaks if not.
It also does not require a town named Austin to fall between the "System" row and the desired row as I do not believe that was a stated requirement.
I have a table of bank staff information that looks like this:
branchNumber Position firstName lastName staffNumber
------------ -------- --------- -------- -----------
25 Manager john doe 11111
25 Secretary robert paulson 11112
25 Secretary cindy lu 11113
66 Manager tim timson 22223
66 Manager jacob jacobson 22224
66 Secretary henry henryson 22225
66 Supervisor paul paulerton 22226
I am actually done with this, but I completed the assignment using SQL common table expressions, and I can't use them in this project, I need them in this format.
branchNumber numOfManagers numOfSecretaries numOfSupervisors totalEmployees
------------ ------------- ---------------- ---------------- --------------
25 1 2 0 3
66 2 1 1 4
My issue is getting multiple columns with information from a row, I have this so far,
SELECT branchNumber, COUNT(*) AS numOfManagers
FROM Staff
WHERE position = 'Manager'
GROUP BY branchNumber, Position;
This outputs the correct information for numOfManagers, but making the next three columns eludes me without using CTE's. I tried sub selects too, with no luck. Anybody have any ideas?
You can use something like this:
select branchnumber,
sum(case when Position ='Manager' then 1 else 0 end) numofManagers,
sum(case when Position ='Secretary' then 1 else 0 end) numofSecretaries,
sum(case when Position ='Supervisor' then 1 else 0 end) numofSupervisors,
count(*) totalEmployees
from yourtable
group by branchnumber
See SQL Fiddle with Demo
Or you can use the PIVOT function:
select branchnumber,
'Manager', 'Secretary', 'Supervisor',
TotalEmployees
from
(
select t1.branchnumber,
t1.position,
t2.TotalEmployees
from yourtable t1
inner join
(
select branchnumber, count(*) TotalEmployees
from yourtable
group by branchnumber
) t2
on t1.branchnumber = t2.branchnumber
) x
pivot
(
count(position)
for position in ('Manager', 'Secretary', 'Supervisor')
) p;

I wasn't sure what could be the title for my question so sorry about that.
I'm trying to write a SQL query to achieve the no. of members who should get reimbursed from a pharmacy.
For example : I went to pharmacy, I took a vaccine but by mistake I paid from my pocket. so now Pharmacy needs to reimburse me that amount. Lets say I have the data like:
MemberId Name ServiceDate PresNumber PersonId ClaimId AdminFee(in $)
1 John 1/1/2011 123 345 456 0
1 John 1/21/2011 123 345 987 20
2 Mike 2/3/2011 234 567 342 0
2 Mike 2/25/2011 234 567 564 30
5 Linda 1/4/2011 432 543 575 0
5 Linda 4/6/2011 987 543 890 0
6 Sonia 2/6/2011 656 095 439 0
This data shows all members from that pharmacy who got reimbursed and who haven't.
I need to find out the member having AdminFee 0 but i also need to check another record for the same member having same PresNumber, same PersonId where the ServiceDate falls within 30 Days of the Original Record.
If another record meets this criteria and the AdminFee field contains a value (is NOT 0) then it means that person has already been reimbursed. So from the data you can see John and Mike have already been reimbursed and Linda and Sonia need to be reimbursed.
Can anybody help me how to write an SQL query on this?
You don't mention what SQL engine you're using, so here is some generic SQL. You'll need to adapt the date math and the return of True/False ( in the second option) to whatever engine you're using:
-- Already reimbursed
SELECT * FROM YourTable YT1 WHERE AdminFee = 0 AND EXISTS
(SELECT * FROM YourTable YT2
WHERE YT2.MemberID = YT1.MemberID AND
YT2.PresNumber = YT1.PresNumber AND
YT2.ServiceDate >= YT1.ServiceDate - 30 AND
AdminFee > 0)
-- Need reimbursement
SELECT * FROM YourTable YT1 WHERE AdminFee = 0 AND NOT EXISTS
(SELECT * FROM YourTable YT2
WHERE YT2.MemberID = YT1.MemberID AND
YT2.PresNumber = YT1.PresNumber AND
YT2.ServiceDate >= YT1.ServiceDate - 30 AND
AdminFee > 0)
or
-- Both in one.
SELECT YT1.*,
CASE WHEN YT2.MemberID IS NULL THEN False ELSE True END AS AlreadyReimbursed
FROM YourTable YT1 JOIN YourTable YT2 ON
YT1.MemberID = YT2.MemberID AND
YT1.PresNumber = YT2.PresNumber AND
YT1.ServiceDate <= YT2.ServiceDate + 30
WHERE YT1.AdminFee = 0 AND YT2.AdminFee > 0)
You need to use datediff function in SQL Server and as parameter to pass day and to join the table above by other alias. I do not have SQL Server but I think it should be like this
Select memberid
from PaymentLog p
inner join PaymentLog d on p.serviceid = d.serviceid
and p.memberid = d.memberid
and p.personid = d.personid
Where adminfee = 0
and datediff(day, p.servicedate, d.servicedate) < 30
I called a table paymentlog
