I have a view in SQL server that i'm trying to convert to work in snowflake. The view uses two functions within it that are called to join onto another table.
I'm following steps provided by another user, but i'm getting lost somewhere in the middle and feel a little stuck.
Here is the query for the SQL Server view:
ALTER VIEW [proj].[pvw_PowerBI_ScrapList]
AS
SELECT
e.Name AS ProductionUnit,
temp.DateTime AS DateTime,
s.Reference AS Shift,
CONVERT(TIME, temp.DateTime) AS Time,
CONVERT(DATE, temp.DateTime - ISNULL((SELECT CAST(MIN(s_first.FromTimeOfDay) AS DateTime) FROM Shift s_first WHERE s_first.FromDay = s.FromDay AND s_first.ShiftCalendarID = s.ShiftCalendarID), CAST('6:00' AS DateTime))) AS ProductionDate,
temp.ScrapReason AS ScrapReason,
temp.Quantity AS ScrapQuantity,
'Manually Registered' AS RegistrationType
FROM (SELECT
CAST(SUM(sreg.ScrapQuantity) AS int) AS Quantity,
sreas.Name As ScrapReason,
DATEADD(MINUTE, 30 * (DATEPART(MINUTE, sreg.ScrapTime) / 30), DATEADD(HOUR, DATEDIFF(HOUR, 0, sreg.ScrapTime), 0)) AS DateTime,

UNION
SELECT

INNER JOIN qms.ScrapReason sreas WITH (NOLOCK) ON sreas.ID = asr.ScrapReasonID
INNER JOIN WorkRequest wr WITH (NOLOCK) ON wr.ID = asr.WorkRequestID
INNER JOIN SegmentRequirementEquipmentRequirement srer WITH (NOLOCK) ON srer.SegmentRequirementID = wr.SegmentRequirementID
GROUP BY DATEADD(MINUTE, 30 * (DATEPART(MINUTE, asr.ScrapTime) / 30), DATEADD(HOUR, DATEDIFF(HOUR, 0, asr.ScrapTime), 0)), srer.EquipmentID, sreas.Name) temp
INNER JOIN Equipment e WITH (NOLOCK) ON e.ID = temp.EquipmentID
INNER JOIN ShiftCalendar sc WITH (NOLOCK) ON sc.ID = dbo.cfn_GetEquipmentShiftCalendarID(temp.EquipmentID, temp.DateTime) -- the function is called here
INNER JOIN Shift s WITH (NOLOCK) ON s.ID = dbo.cfn_GetShiftIDFromDateTime(temp.DateTime, sc.ID) -- the function is called here
i'm ignoring the union for now to try and get something simply working.
The functions are highlighted in this post How to conver this SQL server Function into a CTE in snowflake

I am trying to run this query:
select productID,t.[year]
from (
select ProductID, [year] = year(DT), howMuch = count(*)
from [CONTAINS] as c
join ORDERS as o on c.OrderID = o.OrderID
group by ProductID, year(DT)
) as t
where howMuch >= all (
select howMuch
from (
select ProductID, [year] = year(DT), howMuch = count(*)
from [CONTAINS] as c
join ORDERS as o on c.OrderID = o.OrderID
group by ProductID,year(DT)
) as k
where t.[year] = k.[year]
)
Well, it works. but I want to avoid using the same select query twice. What do you suggest me to do?
It seems your database is SQL Server. If this is the case, you can use a CTE (Common Table Expression), something that was designed for this case.
Your query can be nicely simplified to:
with
q as (
select ProductID, [year]=year(DT),howMuch=count(*)
from [CONTAINS] as c join ORDERS as o on c.OrderID=o.OrderID
group by ProductID,year(DT)
)
select productID, t.[year]
from q as t
where howMuch >= all (
select howMuch from q as k where t.[year]=k.[year]
)
I want to join a table on 4 conditions, of which 2 are very straightforward and 2 other conditions which are more difficult.
The first two:
PMCCONTRACTSTATUS.ContractID = CUSTAMOUNTREPORTTABLE.ContractID
PMCCONTRACTSTATUS.DATAAREAID = CUSTAMOUNTREPORTTABLE.DATAAREAID
The second two:
Only if the FROMDATE from Table PMCCONTRACTSTATUS is lower then the PERIODSTART in Table CUSTAMOUNTREPORTTABLE
AND only if that is the case THEN Take the highest RowNumber. EDIT: Because I want to JOIN the [STATUS] that is the CLOSEST to the PERIODSTART.
EDIT: I Made a sample dataset which only includes the necessary parts to solve the problem.
CREATE TABLE PMCCONTRACTSTATUSLOG2 (
ContractID nvarchar(20)
,[Status] int
,FromDate date
,RowNumber int
);
CREATE TABLE CUSTAMOUNTREPORTTABLE2 (
ContractID nvarchar(20)
,PERIODSTART date
);
INSERT INTO PMCCONTRACTSTATUSLOG2
(ContractID, [Status], FromDate, RowNumber)
VALUES
('HC1','1','01-01-2019','1'),
('HC1','2','01-02-2019','2'),
('HC1','1','01-04-2019','3'),
('HC2','1','01-04-2019','1'),
('HC2','2','01-05-2019','2'),
('HC3','4','01-01-2019','1'),
('HC3','2','01-02-2019','2'),
('HC3','1','01-07-2019','3'),
('HC3','2','01-09-2019','4'),
('HC4','2','01-08-2019','1'),
('HC4','3','01-07-2019','2'),
('HC5','1','01-02-2019','1');
INSERT INTO CUSTAMOUNTREPORTTABLE2
(ContractID, PERIODSTART)
VALUES
('HC1','01-01-2019'),
('HC2','01-01-2019'),
('HC3','01-01-2019'),
('HC5','01-01-2019'),
('HC1','01-02-2019'),
('HC3','01-02-2019'),
('HC5','01-02-2019'),
('HC1','01-03-2019'),
('HC3','01-03-2019'),
('HC5','01-03-2019'),
('HC1','01-04-2019'),
('HC2','01-04-2019'),
('HC3','01-04-2019'),
('HC5','01-04-2019'),
('HC1','01-05-2019'),
('HC2','01-05-2019'),
('HC3','01-05-2019'),
('HC5','01-05-2019');
SELECT * FROM PMCCONTRACTSTATUSLOG2
SELECT * FROM CUSTAMOUNTREPORTTABLE2
I try with the following query to join the PMCCONTRACTSTATUS Table, I know the logic behind the join, but I fail to write a JOIN that combines a CASE WHEN + SELECT statement.
;WITH PMCCONTRACTSTATUS AS
(
SELECT
CONTRACTID
,[STATUS]
,FROMDATE
,DATAAREAID
,ROW_NUMBER() OVER (PARTITION BY CONTRACTID ORDER BY FROMDATE ASC) RN
FROM PMCCONTRACTSTATUSLOG
WHERE [STATUS] <> 10 OR [STATUS] <> 5
)
SELECT
CART.CONTRACTID
,PMCCONTRACTSTATUS.CONTRACTID
,CART.ACCOUNTNUM
,CART.AMOUNTMSTTOTAL
,CART.PERIODSTART
,PMCCONTRACTSTATUS.FROMDATE
,CART.PERIODEND
,CART.NAME
,CART.PMCCONTRACTSTATUSWEIGHTED
,PMCCONTRACTSTATUS.[STATUS]
FROM CUSTAMOUNTREPORTTABLE CART
LEFT JOIN PMCCONTRACTSTATUS
ON PMCCONTRACTSTATUS.CONTRACTID = CART.CONTRACTID
AND PMCCONTRACTSTATUS.DATAAREAID = CART.DATAAREAID
/*AND CASE WHEN PMCCONTRACTSTATUS.FROMDATE <= CART.PERIODSTART
THEN (SELECT MAX(PMCCONTRACTSTATUSLOG.RN) FROM PMCCONTRACTSTATUSLOG)*/
Any suggestions?
This answer is based from my understanding, maybe some parts are missing :
First I try to join with your 3 first conditions in a CTE. And then I create a ROW_NUMBER() based on the DATEDIFF between your 2 dates.
Tell me if it helps :
;WITH
CTE AS (
SELECT
CART.CONTRACTID
,CART.ACCOUNTNUM
,CART.AMOUNTMSTTOTAL
,CART.PERIODSTART
,PMCCONTRACTSTATUSLOG.FROMDATE
,CART.PERIODEND
,CART.NAME
,CART.PMCCONTRACTSTATUSWEIGHTED
,PMCCONTRACTSTATUSLOG.[STATUS]
,ROW_NUMBER() OVER (PARTITION BY CART.CONTRACTID,CART.DATAAREAID ORDER BY DATEDIFF(second,FROMDATE,PERIODSTART) ASC) RN
FROM CUSTAMOUNTREPORTTABLE CART
LEFT JOIN PMCCONTRACTSTATUSLOG
ON PMCCONTRACTSTATUSLOG.CONTRACTID = CART.CONTRACTID
AND PMCCONTRACTSTATUSLOG.DATAAREAID = CART.DATAAREAID
AND PMCCONTRACTSTATUSLOG.FROMDATE <= CART.PERIODSTART
WHERE [STATUS] NOT IN (5,10)
)
SELECT
CONTRACTID
,ACCOUNTNUM
,AMOUNTMSTTOTAL
,PERIODSTART
,FROMDATE
,PERIODEND
,NAME
,PMCCONTRACTSTATUSWEIGHTED
,[STATUS]
FROM CTE
WHERE RN = 1
I believe you should use OUTER APPLY instead of LEFT JOIN
;WITH PMCCONTRACTSTATUS AS
(
SELECT
CONTRACTID
,[STATUS]
,FROMDATE
,DATAAREAID
,ROW_NUMBER() OVER (PARTITION BY CONTRACTID ORDER BY FROMDATE ASC) RN
FROM PMCCONTRACTSTATUSLOG
WHERE [STATUS] <> 10 OR [STATUS] <> 5
)
SELECT
CART.CONTRACTID
,PMCCONTRACTSTATUS.CONTRACTID
,CART.ACCOUNTNUM
,CART.AMOUNTMSTTOTAL
,CART.PERIODSTART
,MAX_PMCCONTRACTSTATUS.FROMDATE
,CART.PERIODEND
,CART.NAME
,CART.PMCCONTRACTSTATUSWEIGHTED
,MAX_PMCCONTRACTSTATUS.[STATUS]
FROM CUSTAMOUNTREPORTTABLE CART
OUTER APPLY (select top 1 *
from PMCCONTRACTSTATUS
where PMCCONTRACTSTATUS.CONTRACTID = CART.CONTRACTID
AND PMCCONTRACTSTATUS.DATAAREAID = CART.DATAAREAID
AND PMCCONTRACTSTATUS.FROMDATE <= CART.PERIODSTART
ORDER BY PMCCONTRACTSTATUSLOG.RN DESC) as MAX_PMCCONTRACTSTATUS
Hi can you please take a look why my query is not returning distinct record. i want result with following condition OE1='SCHEDCHNG', need only recent records per orderid or ordernum means only one record per ordernum or orderid and also dropdate is null. My query is as below
select DISTINCT TOP 100 OE.ORDERID,OE.ID,OE.ORDERNUM,OE.OE4 from OrderExports OE
inner join (
select ORDERNUM, max(OE4) as MaxDate
from OrderExports
group by ORDERNUM
) tm
on OE.ORDERNUM = tm.ORDERNUM and OE.OE4 = tm.MaxDate
inner join orde_ O on OE.ORDERID = O.ORDERID
WHERE OE1='SCHEDCHNG' AND O.DROPDATE is null
Pretty sparse on details here but I think you are wanting something along these lines.
with SortedResults as
(
select OE.ORDERID
, OE.ID
, OE.ORDERNUM
, OE.OE4
, ROW_NUMBER() over(partition by OE.ORDERID, OE.ORDERNUM order by OE.OE4 desc) as RowNum
from OrderExports OE
inner join
(
select ORDERNUM
, max(OE4) as MaxDate
from OrderExports
group by ORDERNUM
) tm on OE.ORDERNUM = tm.ORDERNUM and OE.OE4 = tm.MaxDate
inner join orde_ O on OE.ORDERID = O.ORDERID
WHERE OE1='SCHEDCHNG'
AND O.DROPDATE is null
)
select ORDERID
, ID
, ORDERNUM
, OE4
from SortedResults
where RowNum = 1
You can try using max and group by as below :
SELECT a.ID, max(a.ORDERID) as OrderID, max(a.ORDERNUM) as OrderNum,MAX(OE.OE4) as OE4 FROM
(
--your query
) a
group by a.ID
Here is my table
And my output should be
I want to update the closed_date,time for new_class_desc ='FLM' with next Update_date,Update_time but if new_class_desc is 'FollowupComments' then ignore it and update the next date as Closed_date
I was trying query somewhat like this..
;WITH cte as(
SELECT *
,row_number() OVER(ORDER BY Update_date,Update_time) rn
FROM Table
WHERE Problem_sid = 1435819
)
UPDATE c1 SET Closed_date = c2.Update_date, Closed_time = c2.Update_time
FROM cte c1
JOIN cte c2 ON c1.rn = c2.rn - 1
AND c1.New_class_desc = 'FLM'
AND c2.New_class_desc <> 'FLM'
AND c2.New_class_desc not in ('FollowUpComments')
But in this I am not getting new_class_desc =Bank update_date as Closed_date for Flm.
Please guide here.
WITH cte
AS
(
SELECT *, ROW_NUMBER() OVER(ORDER BY t.Update_date, t.Update_time) AS rno
FROM my_Table t
WHERE t.New_class_desc <> 'FollowUpComments'
)
UPDATE t
SET t.Closed_Date = t1.Closed_Date,
t.Closed_Time = t1.Closed_Time
FROM cte t
JOIN cte t1 ON t.rno = t1.rno + 1
WHERE t.New_class_desc = 'FLM'
