I'm looking to get the sum of a column in certain conditions i.e. depending on whether a column is a parent with subtasks or just a parent with no subtasks. If a task is a parent with subtasks I only want the sum of the "complete" column of the subtasks. If a task is only a parent I would only want the sum of the complete column of the parent. - but only if the tasks(parent or children) are all related to the same user.
E.g. In the following example table:
UserID | Parent_TaskID | TaskID | Complete
------ | ------------- | ------ | --------
435 | 149329 | 161280 | 1
435 | 149330 | 210717 | 2
435 | 149330 | 228100 | 3
435 | 156991 | 149330 | 1
169 | 458764 | 546540 | 2
169 | 456842 | 546541 | 2
169 | 456842 | 458764 | 0
TaskID 149330 is a parent with children 210717 & 228100 so the count for that column for 149330 is 5, i.e. ignoring the complete column for the parent. 161280 is a parent so only would return 0 for that. 546540 is a subtask of 458764, so 458764 would have a sum of 2.
So I think what I the result of this should look like:
TaskID | Sum_complete
------- | ------------
161280 | 1
149330 | 5
546541 | 2
458764 | 2
Any ideas how this could be done?
I've created a table at SqlFiddle http://sqlfiddle.com/#!2/8295f
Thanks,
I can get the parents by using the following:
select t.taskID, t.Parent_taskID, t.userID, t.complete
from task t
where t.Parent_taskID not in (
select tp.taskID
from task tp
where tp.userID = t.userID
)
Based on your description, I think you are asking for the following (using the sample data from the question):
EDIT: Replaced query to eliminate children from the resultset.
declare #Task as Table
( UserId varchar(6), Parent_TaskId varchar(13), TaskId varchar(6), Complete integer );
INSERT INTO #Task ( UserId, Parent_TaskId, TaskId, Complete ) VALUES
('435', '149329', '161280', 1 ),
('435', '149330', '210717', 2 ),
('435', '149330', '228100', 3 ),
('435', '156991', '149330', 1 ),
('169', '458764', '546540', 2 ),
('169', '456842', '546541', 2 ),
('169', '456842', '458764', 0 );
; with QualifiedTasks as (
select UserId, TaskId, Parent_TaskId, Complete,
case when exists ( select 42 from #Task where Parent_TaskId = O.TaskId ) then 1 else 0 end as Parent,
case when exists ( select 42 from #Task where O.Parent_TaskId = TaskId ) then 1 else 0 end as Child, -- Unused, but here for completeness.
case when not exists ( select 42 from #Task where Parent_TaskId = O.TaskId or O.Parent_TaskId = TaskId ) then 1 else 0 end as Loner
from #Task as O )
select L.TaskID, Sum( Coalesce( R.Complete, L.Complete ) ) as Sum_Complete
from QualifiedTasks as L left outer join
QualifiedTasks as R on R.Parent_TaskId = L.TaskId and R.UserId = L.UserId
where L.Parent = 1 or L.Loner = 1
group by L.TaskId;
A couple of obvious optimizations spring to mind. The Parent, Child and Loner columns are redundant, any of the three can be eliminated. Parent can be determined in the summary query by Max( R.Complete ) is not NULL. A clever trick for Child or Loner escapes me at the moment.
This should work (though the data you posted on your question is different than the one on the fiddle):
SELECT ISNULL(B.taskId,A.TaskId) TaskId, SUM(A.Complete) Complete
FROM Task A
LEFT JOIN Task B
ON A.Parent_TaskID = B.taskId
GROUP BY ISNULL(B.taskId,A.TaskId)

This is my code! I want to give a part id and purchase order id to my report and it brings all the related information with those specification. The important thing is that, if we have same purchase order id and part id we need the code to return the result with the highest transaction id. The following code is not providing what I expected. Could you please help me?
SELECT MAX(INVENTORY_TRANS.TRANSACTION_ID), INVENTORY_TRANS.PART_ID
, INVENTORY_TRANS.PURC_ORDER_ID, TRACE_INV_TRANS.QTY, TRACE_INV_TRANS.CREATE_DATE, TRACE_INV_TRANS.TRACE_ID
FROM INVENTORY_TRANS
JOIN TRACE_INV_TRANS ON INVENTORY_TRANS.TRANSACTION_ID = TRACE_INV_TRANS.TRANSACTION_ID
WHERE INVENTORY_TRANS.PART_ID = #PartID
AND INVENTORY_TRANS.PURC_ORDER_ID = #PurchaseOrderID
GROUP BY TRACE_INV_TRANS.QTY, TRACE_INV_TRANS.CREATE_DATE, TRACE_INV_TRANS.TRACE_ID, INVENTORY_TRANS.PART_ID
, INVENTORY_TRANS.PURC_ORDER_ID
The sample of trace_inventory_trans table is :
part_id trace_id transaction id qty create_date
x 1 10
x 2 11
x 3 12
the sample of inventory_trans table is :
transaction_id part_id purc_order_id
11 x p20
12 x p20
I wanted to have the result of biggest transaction which is transaction 12 but it shows me transaction 11
I would use a sub-query to find the MAX value, then join that result to the other table.
The ORDER BY + TOP (1) returns the MAX value for transaction_id.
SELECT
inv.transaction_id
,inv.part_id
,inv.purc_order_id
,tr.qty
,tr.create_date
,tr.trace_id
FROM
(
SELECT TOP (1)
transaction_id,
part_id,
purc_order_id
FROM
INVENTORY_TRANS
WHERE
part_id = #PartID
AND
purc_order_id = #PurchaseOrderID
ORDER BY
transaction_id DESC
) AS inv
JOIN
TRACE_INV_TRANS AS tr
ON inv.transaction_id = tr.transaction_id;
Results:
+----------------+---------+---------------+------+-------------+----------+
| transaction_id | part_id | purc_order_id | qty | create_date | trace_id |
+----------------+---------+---------------+------+-------------+----------+
| 12 | x | p20 | NULL | NULL | 3 |
+----------------+---------+---------------+------+-------------+----------+

What i am trying to do is always sending Product with 0 quantity to the end of an already sorted temp Table without losing current sorting (as i described in the following question How to send Zero Qty Products to the end of a PagedList<Products>?)
I have one Sorted temptable which is filled (it is sorted by what user has selected like Alphabetic , by Price or by Newer product,sorting is based identity id) :
CREATE TABLE #DisplayOrderTmp
(
[Id] int IDENTITY (1, 1) NOT NULL,
[ProductId] int NOT NULL
)
sorted #DisplayOrderTmp :
+------------+---------------+
| id | ProductId |
+------------+---------------+
| 1 | 66873 | // Qty is 0
| 2 | 70735 | // Qty is not 0
| 3 | 17121 | // Qty is not 0
| 4 | 48512 | // Qty is not 0
| 5 | 51213 | // Qty is 0
+------------+---------------+
I want pass this data to web-page, but before it i need to send product with zero quantity to the end of this list without loosing current Sorting by)
My returned data should be like this (sorting doesn't changed just 0 quantity products went to the end of list by their order):
CREATE TABLE #DisplayOrderTmp4
(
[Id] int IDENTITY (1, 1) NOT NULL,
[ProductId] int NOT NULL
)
+------------+---------------+
| id | ProductId |
+------------+---------------+
| 1 | 70735 |
| 2 | 17121 |
| 3 | 48512 |
| 4 | 66873 |
| 5 | 51213 |
+------------+---------------+
P.S: Its My product Table which i have to inner join with tmptable to find qty of products.
Product Table is like this :
+------------+---------------+------------------+
| id | stockqty | DisableBuyButton |
+------------+---------------+------------------+
| 17121 | 1 | 0 |
| 48512 | 27 | 0 |
| 51213 | 0 | 1 |
| 66873 | 0 | 1 |
| 70735 | 11 | 0 |
+------------+---------------+------------------+
What i have tried so far is this : (it works with delay and has performance issue i almost have 30k products)
INSERT INTO #DisplayOrderTmp2 ([ProductId])
SELECT p2.ProductId
FROM #DisplayOrderTmp p2 with (NOLOCK) // it's already sorted table
INNER JOIN Product prd with (NOLOCK)
ON p2.ProductId=prd.Id
and prd.DisableBuyButton=0 // to find product with qty more than 0
group by p2.ProductId order by min(p2.Id) // to save current ordering
INSERT INTO #DisplayOrderTmp3 ([ProductId])
SELECT p2.ProductId
FROM #DisplayOrderTmp p2 with (NOLOCK) //it's already sorted table
INNER JOIN Product prd with (NOLOCK)
ON p2.ProductId=prd.Id
and prd.DisableBuyButton=1 // to find product with qty equal to 0
group by p2.ProductId order by min(p2.Id) // to save current ordering
INSERT INTO #DisplayOrderTmp4 ([ProductId]) // finally Union All this two data
SELECT p2.ProductId FROM
#DisplayOrderTmp2 p2 with (NOLOCK) // More than 0 qty products with saved ordering
UNION ALL
SELECT p2.ProductId FROM
#DisplayOrderTmp3 p2 with (NOLOCK) // 0 qty products with saved ordering
Is there any way To Avoid creating TempTable in this query? send 0
quantity products of first temptable to the end of data-list without
creating three other tempTable , without loosing current ordering based by Identity ID.
My query has performance problem.
I have to say again that the temptable has a identity insert ID column and it is sorted based sorting type which user passed to Stored-Procedure.
Thank You All :)
Make sure the temp table has an index or primary key with Id as the leading column. This will help avoid sort operators in the plan for the ordering:
CREATE TABLE #DisplayOrderTmp
(
[Id] int NOT NULL,
[ProductId] int NOT NULL
,PRIMARY KEY CLUSTERED(Id)
);
With that index, you should be able to get the result without additional temp tables with reasonable efficiency using a UNION ALL query, assuming ProductID is the Product table primary key:
WITH products AS (
SELECT p2.Id, p2.ProductId, prd.stockqty, 1 AS seq
FROM #DisplayOrderTmp p2
JOIN Product prd
ON p2.ProductId=prd.Id
WHERE prd.stockqty > 0
UNION ALL
SELECT p2.Id, p2.ProductId, prd.stockqty, 2 AS seq
FROM #DisplayOrderTmp p2
JOIN Product prd
ON p2.ProductId=prd.Id
WHERE prd.stockqty = 0
)
SELECT ProductId
FROM products
ORDER BY seq, Id;
You mentioned in comments that you ultimately want a paginated result. This can be done in T-SQL by adding OFFSET and FETCH to the ORDER BY clause as below. However, be aware that pagination over a large result set will become progressively slower the further into the result one queries.
WITH products AS (
SELECT p2.Id, p2.ProductId, prd.stockqty, 1 AS seq
FROM #DisplayOrderTmp p2
JOIN Product prd
ON p2.ProductId=prd.Id
WHERE prd.stockqty > 0
UNION ALL
SELECT p2.Id, p2.ProductId, prd.stockqty, 2 AS seq
FROM #DisplayOrderTmp p2
JOIN Product prd
ON p2.ProductId=prd.Id
WHERE prd.stockqty = 0
)
SELECT ProductId
FROM products
ORDER BY seq, Id
OFFSET #PageSize * (#PageNumber - 1) ROWS
FETCH NEXT #PageSize ROWS ONLY;
You could use ORDER BY without using UNION ALL:
SELECT p2.ProductId
FROM #DisplayOrderTmp p2
JOIN Product prd
ON p2.ProductId=prd.Id
ORDER BY prd.DisableBuyButton, p2.id;
DisableBuyButton = 0 - qnt > 0
DisableBuyButton = 1 - qnt = 0
Seems it only needs an extra something in the order by.
An IIF or CASE can be used to give a priority to the sorting.
SELECT tmp.ProductId
FROM #DisplayOrderTmp tmp
JOIN Product prd
ON prd.Id = tmp.ProductId
AND prd.DisableBuyButton IN (0,1)
ORDER BY IIF(prd.DisableBuyButton=0,1,2), tmp.id;
I am using SQL Server 2008 and I would like to only get the activityCode for the orderno when it equals 1 if there are duplicate orderno with the activityCode equals 0.
Also, if the record for orderno activityCode equals 0 then display those records also. But I would only like to display the orderno when the activityCode equals 0 if the same orderno activityCode does not equal 1 or the activityCode only equals 0. I hope this is clear and makes sense but let me know if I need to provide more details. Thanks

*****Updated*****
I have inserted two new records and the results have been updated. The data in the actual table has other numbers besides 0 and 1. The select statement displays the correct orderno's but I would like the other records for the orderno to display also. The partition only populates one record per orderno. If possible I would like to see the records with the same activityCode.

Not totally clear what you are trying to do here but this returns the output you are expecting.
select orderno
, amount
, activityCode
from
(
select *
, RowNum = ROW_NUMBER() over(partition by orderno order by activityCode desc)
from po_v
) x
where x.RowNum = 1
---EDIT---
With the new details this is a very different question. As I understand it now you want all row for that share the max activity code for each orderno. You can do this pretty easily with a cte.
with MyGroups as
(
select orderno
, Activitycode = max(activitycode)
from po_v
group by orderno
)
select *
from po_v p
join MyGroups g on g.orderno = p.orderno
and g.Activitycode = p.Activitycode
Try this
SELECT Orderno,
Amount,
Activitycode
FROM (SELECT orderno,
amount,
activitycode,
ROW_NUMBER()
OVER(
PARTITION BY orderno
ORDER BY activitycode DESC) AS dup
FROM Po_v)dt
WHERE dt.dup = 1
ORDER BY 1
Result
Orderno Amount Activitycode

I am using SQL Server. This is my sample data set:
IDNO| Consigment | SO_Number | Acc Number | OfficeNumber|PL9 |Remarks
--- | -----------| ----------| -----------| ------------|-------|-------
1 | AA12345MY | 1024450191| 8800400431 |B213 |W449401|Stay
2 | AA12345MY | 1024450192| 8800400431 |B213 |W449401|Remove
3 | BA12345MY | 1024460121| 8800400726 |K678 |W229790|Stay
4 | BA12345MY | 1024460124| 8800400726 |K678 |W229790|Remove
I want to put a remarks on row 2 and 4 as it is a duplicates.
Duplicate criteria must match these 4 columns:
Consigment
Acc Number
OfficeNumber
PL9
I am removing the youngest SO number (which one is the latest)
I haven't got a clue on how to start as I never found a perfect reference

One approach here to create a CTE which labels duplicate records and then delete from that CTE:
WITH cte AS (
SELECT *,
ROW_NUMBER() OVER (PARTITION BY Consigment, [Acc Number], OfficeNumber, PL9
ORDER BY SO_Number) rn
FROM yourTable
)
DELETE FROM cte
WHERE rn > 1;
Table One:
IdOne | IdTwo
------+------
32423 | 435
2343 | 345
2344 | 45
Table one gets both idOne and idTwo from two other tables. IdOne stores the ids of a venue. The table from where it gets its id from stores whether or not this venue is active. Users can deactivate a venue and activate it. There are some duplicates that point to the same venue and I would like to set the value of the duplicates(in table one) to the value of the active venue I get from the table that stores this information.
I tried sub querying, correlated querying and I have not gotten far. Any help will be appreciated greatly.
EDIT:
Sorry for the badly worded question. I was a bit frantic. Here is the correct question.
I have two tables. A many to many table associating performances to venues. And a venues table.
The many to many table has the layout:
performance_venue
(
performanceId,
venueId
)
The venue table has the layout:
venue
(
uniqueId,
venueTypeId,
active
)
They are related by venue.uniqueId = performance_venue.venueId. There are instances in performance_venue that refer to venue instances that have an active value of 0. These venues that have an active value of 0 have an updated venue instance in which the active value is 1 and have the same venueTypeId. So, what I would like to do is to update all the performance_venue instances to refer to the venue instances that have an active value of 1 if they currently are referring to a venue instance that has an active value of 0.
Here is an example.
performance_venue
performanceId | venueId
---------------+--------
1 | 1
2 | 2
3 | 3
venue
uniqueId | venueTypeId | active
---------+-------------+-------
1 | 1 | 0
2 | 1 | 1
3 | 2 | 1
Expected result after update
performance_venue
performanceId | venueId
---------------+---------
1 | 2
2 | 2
3 | 3
The solutoin involves constructing a table that has both the active and non-active venue in the same row. Then you just set the performance_venue venueId to the active uniqueId.
UPDATE pv
SET pv.venueId = active_uniqueId
FROM venue v
JOIN performance_venue pv ON pv.venueId = v.uniqueId
JOIN (
SELECT venueTypeId, uniqueId as active_uniqueId
FROM venue
) v_active ON v.venueTypeId = v_active.venueTypeId
WHERE v.active = 0 AND v.venueTypeId in (
SELECT venueTypeId
FROM venue v_sub
WHERE active = 1 and v.venueTypeId = v_sub.venueTypeId
)
AND v.uniqueId != active_uniqueId
UPDATE t1
SET t1.IdTwo = (SELECT top 1 t2.IdTwo FROM TableTwo t2 WHERE t2.IdOne = t1.IdOne AND t2.Active = 1)
FROM TableOne t1
