Data:
| ORIGL_ORDER | ORDER | ITEM | DATE | WHSE | QTY |

Original Desired Result:

| ----------- | ----- | ---- | ---------- | ---- |
| 001 | 113 | 9 | 12/30/2020 | 3 |
| 007 | 211 | 3 | 12/20/2020 | 6 |
| 018 | 390 | 8 | 12/25/2020 | 2 |
Original Question: For each ORIGL_ORDER and ITEM, I would like to get the max(DATE) and the WHSE corresponding to the max(Date). If there are more than one orders with the same max(DATE) then the select the largest ORDER number.
New Desired Result:
| ORIGL_ORDER | ORDER | ITEM | MAX_DATE | WHSE | TOTAL_QTY |
| ----------- | ----- | ---- | ---------- | ---- | --------- |
| 001 | 113 | 9 | 12/30/2020 | 3 | 12 |
| 007 | 211 | 3 | 12/20/2020 | 6 | 4 |
| 018 | 390 | 8 | 12/25/2020 | 2 | 1 |
This answers the original version of the question.
Just use row_number():
select t.*
from (select t.*,
row_number() over (partition by ORIGL_ORDER, item order by date desc, order_number desc) as seqnum
from t
) t
where seqnum = 1;

This is what I have right now:
| time | car_id | order | in_order |
|-------|--------|-------|----------|
| 12:31 | 32 | null | 0 |
| 12:33 | 32 | null | 0 |
| 12:35 | 32 | null | 0 |
| 12:37 | 32 | 123 | 1 |
| 12:38 | 32 | 123 | 1 |
| 12:39 | 32 | 123 | 1 |
| 12:41 | 32 | 123 | 1 |
| 12:43 | 32 | 123 | 1 |
| 12:45 | 32 | null | 0 |
| 12:47 | 32 | null | 0 |
| 12:49 | 32 | 321 | 1 |
| 12:51 | 32 | 321 | 1 |
I'm trying to rank orders, including those who have null values, in this case by car_id.
This is the result I'm looking for:
| time | car_id | order | in_order | row |
|-------|--------|-------|----------|-----|
| 12:31 | 32 | null | 0 | 1 |
| 12:33 | 32 | null | 0 | 1 |
| 12:35 | 32 | null | 0 | 1 |
| 12:37 | 32 | 123 | 1 | 2 |
| 12:38 | 32 | 123 | 1 | 2 |
| 12:39 | 32 | 123 | 1 | 2 |
| 12:41 | 32 | 123 | 1 | 2 |
| 12:43 | 32 | 123 | 1 | 2 |
| 12:45 | 32 | null | 0 | 3 |
| 12:47 | 32 | null | 0 | 3 |
| 12:49 | 32 | 321 | 1 | 4 |
| 12:51 | 32 | 321 | 1 | 4 |
I just don't know how to manage a count for the null values.
Thanks!
You can count the number of non-NULL values before each row and then use dense_rank():
select t.*,
dense_rank() over (partition by car_id order by grp) as row
from (select t.*,
count(order) over (partition by car_id order by time) as grp
from t
) t;
Given the following SQL tables: https://imgur.com/a/NI8VrC7. For each specific ID_t I need to return the MAX() and MIN() value of Cena_c(total price) column of a given ID_t.
| ID_t | Nazwa |
| ---- | ----- |
| 1 | T1 |
| 2 | T2 |
| 3 | T3 |
| 4 | T4 |
| 5 | T5 |
| 6 | T6 |
| 7 | T7 |
| ID | ID_t | Ilosc | Cena_j | Cena_c | ID_p |
| ---- | ---- | ----- | ------ | ------ | ---- |
| 100 | 1 | 1 | 10 | 10 | 1 |
| 101 | 2 | 3 | 20 | 60 | 2 |
| 102 | 4 | 5 | 10 | 50 | 7 |
| 103 | 2 | 2 | 20 | 40 | 5 |
| 104 | 5 | 1 | 30 | 30 | 5 |
| 105 | 7 | 6 | 80 | 480 | 1 |
| 106 | 6 | 7 | 15 | 105 | 2 |
| 107 | 6 | 5 | 15 | 75 | 1 |
| 108 | 3 | 3 | 25 | 75 | 7 |
| 109 | 7 | 1 | 80 | 80 | 5 |
| 110 | 4 | 1 | 10 | 10 | 2 |
| 111 | 2 | 9 | 20 | 180 | 2 |
Based on provided tables the correct result should look like this:
| ID_t | Cena_c_max | Cena_c_min |
| ----- | ---------- | ---------- |
| T1 | 10 | 10 |
| T2 | 180 | 60 |
| T3 | 75 | 75 |
| T4 | 50 | 10 |
| T5 | 30 | 30 |
| T6 | 105 | 75 |
| T7 | 480 | 80 |
Is this even possible?
I haven't found anything yet that I could use to implement my solution.
SELECT concat('T',ID_t), max(Cena_c) as Cena_c_max, min(Cena_c) as Cena_c_min
FROM table
GROUP BY ID_t
Better is to solve it with joins of tables, because it will be avoided in the future if the prefix T is changed to another letter.
Hardcoding should be avoided.
select b.nazva as "Nazva", max(a.cena.c) as "Cena_c_max", min(a.cena.c) as "Cena_c_min"
from table1 as a
left join table2 as b on (
a.id_t = b.id_t
)
group by id_t

Each account has multiple locations and each location has multiple RSCs.
I need to get last three RSCs for each location for AccountA.
I have tried the below query:
SELECT tblAccountwiseLocation.LocId,tblAccountwiseLocation.AccId,tblRSCMaster.RSCNo,tblRSCMaster.DateOfAddition FROM tblAccountwiseLocation
INNER JOIN tblRSCMaster ON tblAccountwiseLocation.LocId= tblRSCMaster.LocId
where tblRSCMaster.AccId=1
But not getting the proper output.
Please help me out.
Thank you all in advance.
You can wrap the existing query inside a common table expression, and use ROW_NUMBER() to get only the last 3 (by tblRSCMaster.DateOfAddition) entries per tblAccountwiseLocation.LocId.
WITH cte AS (
SELECT tblAccountwiseLocation.LocId,
tblAccountwiseLocation.AccId,
tblRSCMaster.RSCNo,
tblRSCMaster.DateOfAddition,
ROW_NUMBER() OVER (PARTITION BY tblAccountwiseLocation.LocId
ORDER BY tblRSCMaster.DateOfAddition DESC) rn
FROM tblAccountwiseLocation
INNER JOIN tblRSCMaster
ON tblAccountwiseLocation.LocId = tblRSCMaster.LocId
AND tblAccountwiseLocation.AccId = tblRSCMaster.AccId
WHERE tblRSCMaster.AccId=1
)
SELECT LocId, AccId, RSCNo, DateOfAddition
FROM cte
WHERE rn <= 3
ORDER BY LocId, AccId, DateOfAddition
An SQLfiddle to test with.
Is this what you need?
select m.*
from (select m.*, row_number() over (partition by accID
order by DateOfAddition desc) as seqnum
from tblRSCMaster
where m.locid = 1
) m
where seqnum <= 3
order by AccId, DateOfAddition;
I think you need to filter on the locid rather than on the AccId to get what you want.
