After applying join condition on two tables I want records which is maximum among records of left table
My query
SELECT a1.*,
t.*,
( a1.trnratefrom - t.trnratefrom )AS minrate,
( a1.trnrateto - t.trnrateto ) AS maxrate
FROM (SELECT a.srno,
trndate,
b.trnsrno,
Upper(Rtrim(Ltrim(b.trnstate))) AS trnstate,
Upper(Rtrim(Ltrim(b.trnarea))) AS trnarea,
Upper(Rtrim(Ltrim(b.trnquality))) AS trnquality,
Upper(Rtrim(Ltrim(b.trnlength))) AS trnlength,
Upper(Rtrim(Ltrim(b.trnunit))) AS trnunit,
b.trnratefrom,
b.trnrateto,
a.remark,
entdate
FROM mstprodrates a
INNER JOIN trnprodrates b
ON a.srno = b.srno)a1
INNER JOIN (SELECT c.srno,
trndate,
d.trnsrno,
Upper(Rtrim(Ltrim(d.trnstate))) AS trnstate,
Upper(Rtrim(Ltrim(d.trnarea))) AS trnarea,
Upper(Rtrim(Ltrim(d.trnquality))) AS trnquality,
Upper(Rtrim(Ltrim(d.trnlength))) AS trnlength,
Upper(Rtrim(Ltrim(d.trnunit))) AS trnunit,
d.trnratefrom,
d.trnrateto,
c.remark,
entdate
FROM mstprodrates c
INNER JOIN trnprodrates d
ON c.srno = d.srno) AS t
ON a1.trnstate = t.trnstate
AND a1.trnquality = t.trnquality
AND a1.trnunit = t.trnunit
AND a1.trnlength = t.trnlength
AND a1.trnarea = t.trnarea
AND a1.remark = t.remark
WHERE t.srno = (SELECT MAX(srno)
FROM a1
WHERE srno < a1.srno)
If you mean to say,
you want Records exist in Left table but not in right then use LEFT OUTER JOIN.

I use SQLServer 2014 (120 compatibility mode) and I want a parallel execution plan for my query, but because of a few fields, it isn't. As long as field pi.Name AS ProcessName is commented I have parallelism but when it is active it isn't. The same problem is with other commented fields. Is the reason connected with an index which covers pi.ProcessGuid but not pi.Name or something more?
ExecutionPlan_Parallel
ExecutionPlan_Single
ExecutionPlan_Original
When I commented on those few fields ExecutionPlan starts to be parallel and from 30 minutes query runs only 11 seconds.

My select statement returns the ids from the tables I have joined correctly(393, starting at 92 and going up 484, its not a PK field, so some ids can be used more then once) there is a total of 550 rows I need to update, when I run the update it only adds the number 92 to the table for all 550 rows.
update movements set [location] = locaID.id FROM (
SELECT
lo.id
FROM [Harvest_Transactions] ht
left join [Harvest_Master_Shift] hms on ht.Harvest_Master_id = hms.Harvest_Master_id
left join [Greenhouse_Troughs] gt on ht.Trough = gt.Greenhouse_Trough_id
left join [batches] b on b.name = hms.Batch_id
left join [phases] p on p.batch = b.id and p.[type] = 3
left join #loc lo on lo.name = gt.Trough_No and lo.area = gt.SQM_per_Trough and lo.Bay_id = gt.Bay_id
where ht.Number_of_Plants_Harvested != 0 and (hms.CreatedOn <= '2020-02-05 09:33:00.000' OR hms.CreatedOn is null )
)locaID where product = 14
what am I missing so it updates with the correct values?
My first impression of your query is that only the rows with product = 14 in movements table will be updated with the single value coming from the subquery.
If you want to update the values based on another derived table, you need some way to link the rows together - i.e a JOIN between your table being updated and the table that holds the other data (see here )
What is the common column between movements and
SELECT
lo.id
FROM [Harvest_Transactions] ht
left join [Harvest_Master_Shift] hms on ht.Harvest_Master_id = hms.Harvest_Master_id
left join [Greenhouse_Troughs] gt on ht.Trough = gt.Greenhouse_Trough_id
left join [batches] b on b.name = hms.Batch_id
left join [phases] p on p.batch = b.id and p.[type] = 3
left join #loc lo on lo.name = gt.Trough_No and lo.area = gt.SQM_per_Trough and
lo.Bay_id = gt.Bay_id
where ht.Number_of_Plants_Harvested != 0 and (hms.CreatedOn <= '2020-02-05
09:33:00.000' OR hms.CreatedOn is null )
The rough syntax shouldI think be
UPDATE movements
set [location] = locaID.id
FROM movements
JOIN (
SELECT
lo.id
FROM [Harvest_Transactions] ht
left join [Harvest_Master_Shift] hms on ht.Harvest_Master_id = hms.Harvest_Master_id
left join [Greenhouse_Troughs] gt on ht.Trough = gt.Greenhouse_Trough_id
left join [batches] b on b.name = hms.Batch_id
left join [phases] p on p.batch = b.id and p.[type] = 3
left join #loc lo on lo.name = gt.Trough_No and lo.area = gt.SQM_per_Trough and
lo.Bay_id = gt.Bay_id
where ht.Number_of_Plants_Harvested != 0 and (hms.CreatedOn <= '2020-02-05
09:33:00.000' OR hms.CreatedOn is null )
) locaID
ON movements.<some column> = locaID.<some column>
I have a table with values en date/timstamps. This table is dbo.meterdata.value. The output that i want to see is as followed: The latest date/timestamp (Max) but only the ones where te latest date/timestamp is last week. My Query is:
SELECT dbo.meter.DataImportCode
,dbo.meter.NAME
,dbo.company.NAME
,dbo.meter.MeterNumber
,MAX(dbo.meterdata.RoundedTimeStamp) AS 'laatste datum'
,dbo.MeterOperator.Description
,dbo.meter.CumulativeReadings
FROM dbo.meter
LEFT OUTER JOIN DBO.MeterData ON dbo.meter.MeterID = dbo.meterdata.MeterID
JOIN DBO.Site ON dbo.meter.SiteID = dbo.site.SiteID

GROUP BY dbo.meter.DataImportCode
,dbo.company.NAME
,dbo.meter.NAME
,dbo.meter.MeterNumber
,dbo.MeterOperator.Description
,dbo.meter.CumulativeReadings

Example
Thank you for help and support
Try the following:
select dbo.meter.DataImportCode, dbo.meter.Name, dbo.company.Name, dbo.meter.MeterNumber,MAX(dbo.meterdata.RoundedTimeStamp) AS 'laatste datum', dbo.MeterOperator.Description, dbo.meter.CumulativeReadings
from dbo.meter
LEFT OUTER JOIN DBO.MeterData ON dbo.meter.MeterID = dbo.meterdata.MeterID
JOIN DBO.Site on dbo.meter.SiteID = dbo.site.SiteID
JOIN DBO.Company on dbo.site.CompanyID = dbo.company.CompanyID
JOIN DBO.MeterOperator on dbo.meter.MeterOperatorID = dbo.MeterOperator.MeterOperatorID
--WHERE (select (dbo.meterdata.roundedtimestamp) from dbo.MeterData) < DateAdd(DD,-7,GETDATE() )
--AND dbo.meterdata.RoundedTimeStamp is not null
GROUP BY dbo.meter.DataImportCode, dbo.company.name, dbo.meter.Name, dbo.meter.MeterNumber, dbo.MeterOperator.Description, dbo.meter.CumulativeReadings
HAVING [laatste datum] < DateAdd(day,-7,GETDATE())
If I understood you right, what you want to do is filter out the data after it has been grouped. This is done using the HAVING clause of the SELECT statement, as the above query depicts.

This is my code.
I could run it in SQL Server,
But now i have to use Mariadb,
and Mariadb doesn't use "WITH AS".
So is there any other way to change this code for the same result?
As we can see, there's "INNER JOIN KPILibHier" too inside the CTE,
So I couldn't make ordinary subquery as usual.
Just moving the contents of the CTE to a derived table should provide something usable. Something like;
SELECT DISTINCT Z.kpi_name AS libname, Z.kpilib_code AS libcode,
Z.parent_code AS pcode, Z.depth, Z.iscategory, PK.target
FROM
( SELECT K.kpilib_code, K.parent_code, K.kpi_name_en AS kpi_name, K.kpi_depth AS depth, K.iscategory
FROM TPMDPERIODKPILIB K
INNER JOIN TPMDPERIODKPI PK ON PK.period_code = K.period_code
UNION ALL
SELECT A.kpilib_code, A.parent_code, A.kpi_name_en, A.kpi_depth, A.iscategory
FROM TPMDPERIODKPILIB A
) z
INNER JOIN z AS B ON A.kpilib_code = B.parent_code
LEFT JOIN TPMDPERIODKPILIB KPI
ON KPI.kpilib_code = Z.kpilib_code
LEFT JOIN TPMDPERIODKPI PK
ON PK.period_code = KPI.period_code
ORDER BY Z.depth, Z.kpi_name
I have a sql that is as under:
SELECT ib.branch_no,
ib.on_hand,
p.weightedav,
p.item_code,
FROM physical p
INNER JOIN
item_branch as ib on p.item_code = ib.item_code
WHERE ib.on_hand <> 0
This SQL returns only those branch_no that have on_hand <> 0.
I am trying to get all the branch_nos irrespective of the on_hand field, but while still using the where on_hand clause.
Taking the on_hand clause away solves my problem, but gives me large amount of un-needed rows with 0's.
I am using SQL SERVER 2008 R2.
Thanks in advance for any guidance. Please apologize if I am missing any information.
