I have a list of customers that can have a single, or multiple, service listed. In the table that houses the changes over time there is an indicator of 'Added' or 'Removed'.
What I need: determine those service(s) that are currently active, if at all.
Here is a sample set of data:
CUST_ID SRV_ID STATUS ACTION_DATE
12345 102 Added 1/31/17 10:15
12345 189 Added 4/18/17 15:37
12345 189 Removed 4/21/17 14:08
12345 194 Added 5/2/17 14:43
12345 194 Removed 5/5/17 10:02
12345 194 Added 5/5/17 13:06
12345 69 Added 4/19/17 9:36
12345 69 Removed 5/2/17 14:43
12345 73 Added 4/20/17 10:21
12345 73 Removed 4/25/17 11:20
12345 95 Added 5/4/17 9:48
12345 95 Removed 5/4/17 10:05
Records to be returned: 102 on 1/31/17 10:15 and 194 on 5/5/17 13:06
You can find the latest row for each cust_id and serv_id using top 1 with ties and window function row_number and then filter those with status "Added":
select *
from (
select top 1
with ties *
from your_table
order by row_number() over (
partition by cust_id, srv_id
order by action_date desc
)
) t
where status = 'Added'
Produces:
CUST_ID SRV_ID STATUS ACTION_DATE
12345 102 Added 2017/01/31 10:15
12345 194 Added 2017/05/05 13:06
Demo
Like this:
SELECT SRV_ID
FROM YourTable
GROUP BY SRV_ID
HAVING MAX(CASE WHEN STATUS='Added' THEN ACTION_DATE END)
> MAX(CASE WHEN STATUS='Removed' THEN ACTION_DATE END)

Below is my table:
id order_number order_date order_details
---------------------------------------------
1 222 01-01-2020 44
2 222 02-01-2020 66
3 222 03-01-2020 20
4 223 03-01-2020 33
5 224 04-01-2020 55
6 225 02-01-2020 77
I want to have sum(order_details) where order_number = 222
like this table
order_date sum_order_details
----------------------------------
01-01-2020 130
02-01-2020 130
03-01-2020 130
I tried the below but it doesn't work
select order_number , order_date , sum(order_details) sum_orders from ex
group by order_number
having order_number = 222
It seems like you're after this is a windowed SUM:
SELECT order_date,
SUM(order_details) OVER () AS sum_orders
FROM YourTable
WHERE order_number = 222;
I have a Employee Wages table like this, with their EmpID and their wages.
EmpId | Wages
================
101 | 1280
102 | 1600
103 | 1400
104 | 1401
105 | 1430
106 | 1300
I need to write a Stored Procedure in SQL Server, to group the Employees according to their wages, such that similar salaried people are in groups together and the deviations within the group is as minimum as possible.
There are no other conditions or rules mentioned.
The output should look like this
EmpId | Wages | Group
=======================
101 | 1280 | 1
106 | 1300 | 1
103 | 1400 | 2
104 | 1401 | 2
105 | 1430 | 2
102 | 1600 | 3
You can use a query like the following:
SELECT EmpId, Wages,
DENSE_RANK() OVER (ORDER BY CAST(Wages - t.min_wage AS INT) / 100) AS grp
FROM mytable
CROSS JOIN (SELECT MIN(Wages) AS min_wage FROM mytable) AS t
The query calculates the distance of each wage from the minimum wage and then uses integer division by 100 in order to place records in slices. So all records that have a deviation that is between 0 - 99 off the minimum wage are placed in the first slice. The second slice contains records off by 100 - 199 from the minimum wage, etc.
You can for +-30 deviation as the below:
DECLARE #Tbl TABLE (EmpId INT, Wages INT)
INSERT INTO #Tbl
VALUES
(99, 99),
(100, 101),
(101, 1280),
(102, 1600),
(103, 1400),
(104, 1401),
(105, 1430),
(106, 1300)
;WITH CTE AS ( SELECT *, ROW_NUMBER() OVER (ORDER BY Wages) AS RowId FROM #Tbl )
SELECT
A.EmpId ,
A.Wages ,
DENSE_RANK() OVER (ORDER BY MIN(B.RowId)) [Group]
FROM
CTE A CROSS JOIN CTE B
WHERE
ABS(B.Wages - A.Wages) BETWEEN 0 AND 30 -- Here +-30
GROUP BY A.EmpId, A.Wages
ORDER BY A.Wages
Result:
EmpId Wages Group
----------- ----------- --------------------
99 99 1
100 101 1
101 1280 2
106 1300 2
103 1400 3
104 1401 3
105 1430 3
102 1600 4
I am trying to retrieve the most recent entry of a record in an Access report. The query I have gives me the results in SQL-Server but row_number is not compatible with Access. Its been suggested that I use the max function in Access. Can you assist me in generating this report?

The following query is generating below output but I need to group employees and sum workhrs and then pivot RM_ROOM and RM_SCR
WITH pivot_data AS (
SELECT eNAME,workhrs,room, 'RM' as RM,SCR from PRODUCTIVITY p,PRODUCTIVITYd d, emp e, ROOMS R
where p.PRODUCTIVITYID=d.PRODUCTIVITYID and e.empno=p.employeeid
AND R.ID=P.ROOMID
)
SELECT *
FROM pivot_data
PIVOT (
MIN(room) as room,min(scr) as SCR --<-- pivot_clause
FOR RM--<-- pivot_for_clause
IN ('RM') --<-- pivot_in_clause
)
Current Output:
ENAME WORKHRS 'RM'_ROOM 'RM'_SCR
JONES 3.6 101 53
ALLEN 6 102 22
ALLEN 1.32 101 43
Desired Output:
ENAME WORKHRS 'RM'_ROOM 'RM'_SCR 'RM'_ROOM 'RM'_SCR
JONES 3.6 101 53 - -
ALLEN 7.32 101 43 102 22
You are pivoting on a fixed value, the string literal 'RM', so you're really not doing anything useful in the pivot - the output is the same as you'd get from running the 'pivot_data' query on its own:
SELECT eNAME,workhrs,room, SCR from PRODUCTIVITY p,PRODUCTIVITYd d, emp e, ROOMS R
where p.PRODUCTIVITYID=d.PRODUCTIVITYID and e.empno=p.employeeid
AND R.ID=P.ROOMID;
ENAME WORKHRS ROOM SCR
----- ---------- ---------- ----------
JONES 3.6 101 53
ALLEN 1.32 101 43
ALLEN 6 102 22
You want the aggregate workhrs for each employee, and a pivot of the rooms they sold. If you change that query to get the analytic sum of workhrs and a ranking of the room/scr values (and using modern join syntax) you get:
select e.ename, r.room, p.scr,
sum(d.workhrs) over (partition by e.ename) as wrkhrs,
rank() over (partition by e.ename order by r.room, p.scr) as rnk
from productivity p
join productivityd d on d.productivityid = p.productivityid
join emp e on e.empno=p.employeeid
join rooms r on r.id = p.roomid;
ENAME ROOM SCR WRKHRS RNK
----- ---------- ---------- ---------- ----------
ALLEN 101 43 7.32 1
ALLEN 102 22 7.32 2
JONES 101 53 3.6 1
You can then pivot on that generated rnk number:
with pivot_data as (
select e.ename, r.room, p.scr,
sum(d.workhrs) over (partition by e.ename) as wrkhrs,
rank() over (partition by e.ename order by r.room, p.scr) as rnk
from productivity p
join productivityd d on d.productivityid = p.productivityid
join emp e on e.empno=p.employeeid
join rooms r on r.id = p.roomid
)
select *
from pivot_data
pivot (
min(room) as room, min(scr) as scr --<-- pivot_clause
for rnk --<-- pivot_for_clause
in (1, 2, 3) --<-- pivot_in_clause
);
ENAME WRKHRS 1_ROOM 1_SCR 2_ROOM 2_SCR 3_ROOM 3_SCR
----- ---------- ---------- ---------- ---------- ---------- ---------- ----------
ALLEN 7.32 101 43 102 22
JONES 3.6 101 53
You need to know the maximum number of rooms any employee may have - i.e. the highest rnk could ever be - and include all of those in the in clause. Which means you're likely to end up with empty columns, as in this example where there is no data for 3_room or 3_scr. You can't avoid that though, unless you get an XML result or generate the query dynamically.
What you are saying makes no sense. What do you mean by "pivot RM_ROOM"? So I have to guess. I am guessing you want to group employees and sum workhrs, and then pivot the result. The "Output" you show seems to be the output for pivot_data, your subquery.
Your answer will only have eNAME and for each of them, a count of hours worked. So you don't need to SELECT the room numbers in the pivot_data subquery. You only need eNAME and workhrs. Then it is a simple matter of using the PIVOT syntax:
WITH pivot_data AS (
SELECT eNAME, workhrs FROM PRODUCTIVITY p,PRODUCTIVITYd d, emp e, ROOMS R
where p.PRODUCTIVITYID=d.PRODUCTIVITYID and e.empno=p.employeeid
AND R.ID=P.ROOMID
)
SELECT *
FROM pivot_data
PIVOT (
SUM(workhrs)
FOR eNAME IN ('JONES', 'ALLEN')
)
/
Output:
'JONES' 'ALLEN'

I have data looks like this:
Order No. Name Date Unit Price Freight
001 ABC 1-16 232 25
001 ABC 1-16 55 25
001 ABC 1-16 156 25
002 DEF 2-5 478 16
002 DEF 2-5 356 16
I am trying to let freight cost only show once in my table, the result would look like:
Order No. Name Date Unit Price Freight
001 ABC 1-16 232 25
001 ABC 1-16 55 0
001 ABC 1-16 156 0
002 DEF 2-5 478 16
002 DEF 2-5 356 0
Please help me with this
Here is a query to get what you want:
SELECT
order_no, name, theDate, unit_price,
case
when row_number() OVER (PARTITION by order_no ORDER BY order_no) = 1 then freight
else 0
end as freight
from yourTable
This looks at all rows for each order number and provides the row number. If it's row 1 of that order it uses the values of the freight column, otherwise it uses 0.
Note that I'm assuming that the freight value is the same across all rows for the same order number.
