I need to do Ranking, if the value is negative, then sort it by Asc, if it is positive then sort it by Desc
select
Itemcode,
isnull(sum(ss.DiscQty * ss.Cost),0) DescCost,
RANK()OVER(Partition by Itemcode order by
case when isnull(sum(ss.DiscQty * ss.Cost),0) < 0 THEN isnull(sum(ss.DiscrepancyQty * ss.Cost),0) END ASC,
case when isnull(sum(ss.DiscQty * ss.Cost),0) > 0 THEN isnull(sum(ss.DiscQty * ss.Cost),0) END DESC
) RANKS
from
ss
Group by
ItemNo
Is this the pattern you are after?
Have simplified the code to highlight what is happening
;WITH Example (n) AS
(
SELECT 1 UNION ALL
SELECT 2 UNION ALL
SELECT 3 UNION ALL
SELECT -1 UNION ALL
SELECT -2 UNION ALL
SELECT -3
)
SELECT n
,ROW_NUMBER() OVER (ORDER BY ABS(n)-0 DESC)
FROM Example
ORDER BY n,ROW_NUMBER() OVER (ORDER BY ABS(n)-0 DESC)
You cannot change the criteria dynamically. Do the following
SELECT
Brand,
ItemNo,
RANK() OVER (PARTITION BY ItemNo ORDER BY
CASE WHEN ISNULL(Disc, 0) > 0 THEN SUM(Quantity * Item.Cost) ELSE 0 END DESC,
CASE WHEN ISNULL(ST_ItemEntry.Discrepancy, 0) < 0 THEN SUM(Quantity * Item.Cost) ELSE 0 END ASC
) AS [Rank]
FROM
item
GROUP BY
Brand,ItemNo

I have the following SQL code
SELECT (COUNT(*) filter (WHERE has_a)) AS count_a,
COUNT(*) AS total_count,
process_date
FROM(SELECT process_date::date AS process_date,
(CASE WHEN (columnA > 0) THEN true ELSE false END) AS has_a
FROM my_table)
temptable
GROUP BY process_date
LIMIT 5;
which gives the following table
I want to create a column called percent_a with value (count_a/total_count)*100 grouped by process_date. E.g for row 1 the new column would have value 49.4 i.e. (1030/2085)*100.
I have tried
SELECT process_date,
((COUNT(*) filter (WHERE has_a))/COUNT(*) * 100) AS percent_a,
FROM(SELECT process_date::date AS process_date,
(CASE WHEN (columnA > 0) THEN true ELSE false END) AS has_a,
FROM my_table)
temptable
GROUP BY process_date
ORDER BY process_date DESC
LIMIT 1;
But this just gave 0s.
How can I create the column to display the % I want? I think something is happening with the GROUP BY but I don't know how to fix it.
It's because count returns an integer, you just need to cast it:
SELECT process_date,
(((COUNT(*) filter (WHERE has_balance))::DOUBLE PRECISION)/COUNT(*) * 100) AS percent_a,
FROM(SELECT process_date::date AS process_date,
(CASE WHEN (columnA > 0) THEN true ELSE false END) AS has_a,
FROM my_table)
temptable
GROUP BY process_date
ORDER BY process_date DESC
LIMIT 1;
This code
DECLARE #SNH TABLE
(
cntDATE date,
cntQUEUE varchar(10),
[cntINKTONERBLACK] int
)
INSERT INTO #SNH (cntDATE, cntQUEUE, [cntINKTONERBLACK])
VALUES ('2001-04-04', 'Queue01', 3),
('2001-04-05', 'Queue01', 1),
('2001-04-06', 'Queue01', 100)
SELECT TOP 5
[cntQUEUE] AS cntqueue,
[cntdate],
[cntINKTONERBLACK],
(CASE
WHEN LAG(cntinktonerblack) OVER (PARTITION BY cntqueue ORDER BY cntqueue, cntdate) < cntinktonerblack
THEN 1
ELSE 0
END) AS signalcolumn
FROM
#SNH
WHERE
[cntINKTONERBLACK] IS NOT NULL
ORDER BY
cntqueue, cntDATE ASC
gives the following table
cntqueue
cntdate
cntINKTONERBLACK
signalcolumn
Queue01
2001-04-04
3
0
Queue01
2001-04-05
1
0
Queue01
2001-04-06
100
1
Is there a way to count '1' in signal column and group 1st column to have?
cntqueue
NumberOfJumps
Queue01
1
You can use a subquery:
select cntqueue, sum(signalcolumn)
from (select cntQUEUE,
(case when lag(cntinktonerblack) over (partition by cntqueue order by cntqueue, cntdate) < cntinktonerblack
then 1 else 0
end) as signalcolumn
from [watchdocstatsSU].[dbo].[queuescounters]
where [cntINKTONERBLACK] is NOT null
) q
group by cntqueue
order by cntqueue;
I need a stored procedure for solve this problem. I have table with name Items With Values
id qty
1 5
2 10
3 15
If a parameter value = 10, and the table will be
id qty
1 0
2 5
3 15
If your dbms supports window functions (ms sql server 2012+ is used below):
declare #prm int = 10;
select id, qty
, case
when qty + tot <= #prm then 0
when tot > #prm then qty
else (qty + tot) - #prm
end currQty
from (
select id, qty, coalesce (sum(qty) over(order by id rows between unbounded preceding and 1 preceding), 0) tot
from
-- your table here
(values
(1,5 )
,(2,10)
,(3,15)
) tbl (id,qty)
) t;
Basically, you want to use a cumulative sum for this purpose. The rest is just arithmetic. I like to phrase this as:
select t.*,
(case when running_qty <= #parameter
then 0
when running_qty - qty <= #parameter
then running_qty - #parameter
else qty
end) as new_qty
from (select t.*,
sum(qty) over (order by id) as running_qty
from t
) t;
Here is a db<>fiddle.
I have a table as below :
How can I craft a SQL select statement so that MIN AND MAX EVENT DATE groups results by FLAG (0,1)?
So the result would be:
Just do conditional aggregation with use of window function
SELECT card_no, descr_reader,
max(CASE WHEN flag = 0 THEN event_date END) date_in,
max(CASE WHEN flag = 1 THEN event_date END) date_out
FROM
(
SELECT *,
COUNT(flag) OVER (PARTITION BY flag ORDER BY id) Seq
FROM table t
)t
GROUP BY card_no, descr_reader, Seq
An alternative if Window function does not work:
SELECT
t1.card_no, t1.descr_reader,
t1.event_date date_in,
(select top 1 event_date from test t2
where t2.card_no = t1.card_no and
t2.reader_no = t1.reader_no and
t2.descr_reader = t1.descr_reader and
t2.event_date > t1.event_date and
t2.flag = 1
order by t2.event_date ) as date_out
FROM test t1
WHERE t1.flag = 0
I'm not able to use where condition on the row number within the same select statement. Results are not consistent if I use a different select statement for applying condition over the rownumber...

check_row here is not recognised. Please help
SQL order of execution.
FROM clause
WHERE clause
GROUP BY clause
HAVING clause
SELECT clause
ORDER BY clause
the check_row alias was made in the select part so it doesn't exist yet in the context
EDIT
done some testing. can't seem to get it right. as a temporary solution you could attempt to put the
ROW_NUMBER() over(...
in the where clause aswell

another option from the MSDN website is
