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 3 tables in that 2 tables are master table and 3rd is transaction table. i need to get count from transaction table for each value in other two table without loosing rows in mater table
i need result like below
Table layout for understanding
This is the code i have tried,
select s.status_name, e.machine_group_name, qty = COALESCE(COUNT(e.id),0)
from tbl_status s
left outer JOIN tbl_transaction as e ON e.status_name = s.status_name
group by e.machine_group_name, s.status_name
This is solution i have figured:
select m.machine_group_name, s.status_name, qty = COUNT(e.id) from
tbl_machine_group as m
cross join tbl_status as s
left outer join tbl_transaction as e on e.status_name = s.status_name
and e.machine_group_name = m.machine_group_name
group by m.machine_group_name, s.status_name
order by machine_group_name
select
MC_Group_Name
,Status_Name
,count(1) as [Count of Transaction]
from
tbl_Transaction tbl_3
left join tbl_Machine_Group tbl_1
on tbl_3.MC_Group_Name = tbl_1.MC_Group_Name
left join tbl_Status tbl_2
on tbl_3.Status_Name = tbl_2.Status_Name
group by
MC_Group_Name
,Status_Name
We have many complex queries which involve a lot of columns and joins (see the example below) that are implemented as views.
In some cases these queries return duplicate rows which then have to be programmatically removed by the consuming app. Therefore, we would like to enhance the SQL query to eliminate the duplicates, and speed up the retrieval process.
I know that I can use OVER / PARTITION BY logic to do this, but I am not sure of how to modify the queries to obtain a working syntax.
Here is an example:

you can use row_number as below: Below query will not select duplicate only on OrderNumber, if you need to add other columns you add accordingly
Select * from (
Select
RowN = Row_Number() over( partition by Main.MfgOrder.OrderNumber order by Main.MfgOrder.OrderNumber),
--- All your select columns and all your query with joins
) a
Where a.RowN = 1
Is the entire row duplicated exactly? If so then just add DISTINCT
SELECT DISTINCT
...
FROM
...
If you are getting duplicate rows where most columns the same but some columns are different then GROUP BY the columns that are the same and select MIN(column_name) for the ones that are causing the extra rows to appear.
I have these queries :
SELECT
dbo.Lines.Unit, dbo.Lines.LineNumber, dbo.Lines.DocumentNumber,
dbo.BaseMaterials.Name AS MaterialName,
dbo.MaterialDescriptions.Name AS MaterialDescription,
dbo.MaterialDescriptions.Description,
dbo.MaterialScopes.ScopeName, dbo.MaterialScopeObjectNames.ObjectName,
dbo.MaterialDescriptions.Size1, dbo.MaterialDescriptions.Size2,
dbo.MaterialDescriptions.ItemCode, dbo.Materials.Quantity,
dbo.Materials.Discipline, dbo.Materials.Id, dbo.Lines.Id AS LineId
FROM
dbo.Materials
INNER JOIN
dbo.Lines ON dbo.Materials.LineId = dbo.Lines.Id
INNER JOIN
dbo.BaseMaterials ON dbo.Lines.BaseMaterialId = dbo.BaseMaterials.Id
INNER JOIN
dbo.MaterialDescriptions ON dbo.Materials.MaterialDescriptionId = dbo.MaterialDescriptions.Id
INNER JOIN
dbo.MaterialScopes ON dbo.MaterialDescriptions.MaterialScopeId = dbo.MaterialScopes.Id
INNER JOIN
dbo.MaterialScopeObjectNames ON dbo.MaterialDescriptions.MaterialScopeObjectId = dbo.MaterialScopeObjectNames.Id
It returns 16000 records. I have another tables with joints name that has a relation with material table on lineId every material can have multi joints so my query when I add joints table is like this :
SELECT
dbo.Lines.Unit, dbo.Lines.LineNumber, dbo.Lines.DocumentNumber,
dbo.BaseMaterials.Name AS MaterialName,
dbo.MaterialDescriptions.Name AS MaterialDescription,
dbo.MaterialDescriptions.Description, dbo.MaterialScopes.ScopeName,
dbo.MaterialScopeObjectNames.ObjectName, dbo.MaterialDescriptions.Size1,
dbo.MaterialDescriptions.Size2, dbo.MaterialDescriptions.ItemCode,
dbo.Materials.Quantity, dbo.Materials.Discipline, dbo.Materials.Id,
dbo.Lines.Id AS LineId, dbo.Joints.TestPackageId
FROM
dbo.Materials
INNER JOIN
dbo.Lines ON dbo.Materials.LineId = dbo.Lines.Id
INNER JOIN
dbo.BaseMaterials ON dbo.Lines.BaseMaterialId = dbo.BaseMaterials.Id
INNER JOIN
dbo.MaterialDescriptions ON dbo.Materials.MaterialDescriptionId = dbo.MaterialDescriptions.Id
INNER JOIN
dbo.MaterialScopes ON dbo.MaterialDescriptions.MaterialScopeId = dbo.MaterialScopes.Id
INNER JOIN
dbo.MaterialScopeObjectNames ON dbo.MaterialDescriptions.MaterialScopeObjectId = dbo.MaterialScopeObjectNames.Id
INNER JOIN
dbo.Joints ON dbo.Materials.LineId = dbo.Joints.LineId
As you can see in the last line i make a join between joints and materials to access the testpackageid column in joints table .but my result returns 220000records .How can i change the join type i mean left or right to just returns 16000 records with its testpackageId
You can't using JOIN. However, you can using CROSS APPLY:
FROM . . .
dbo.MaterialScopeObjectNames
ON dbo.MaterialDescriptions.MaterialScopeObjectId = dbo.MaterialScopeObjectNames.Id CROSS APPLY
(SELECT TOP 1 j.*
FROM dbo.Joints j
WHERE dbo.Materials.LineId = j.LineId
) J
Normally, you would include an ORDER BY when using TOP so you have some control over the row being returned.
Also note that the use of table aliases makes the query easier to write and to read.
You can get it very easily with just a subquery. Leave your query as it is, and add a subquery to get that information from Joints.
SELECT dbo.Lines.Unit, dbo.Lines.LineNumber, dbo.Lines.DocumentNumber, dbo.BaseMaterials.Name AS MaterialName, dbo.MaterialDescriptions.Name AS MaterialDescription, dbo.MaterialDescriptions.Description,
dbo.MaterialScopes.ScopeName, dbo.MaterialScopeObjectNames.ObjectName, dbo.MaterialDescriptions.Size1, dbo.MaterialDescriptions.Size2, dbo.MaterialDescriptions.ItemCode, dbo.Materials.Quantity,
dbo.Materials.Discipline, dbo.Materials.Id, dbo.Lines.Id AS LineId,
(select top 1 dbo.Joints.TestPackageId from dbo.Joints where dbo.Joints.LineId = dbo.Materials.LineId)
FROM dbo.Materials INNER JOIN
dbo.Lines ON dbo.Materials.LineId = dbo.Lines.Id INNER JOIN
dbo.BaseMaterials ON dbo.Lines.BaseMaterialId = dbo.BaseMaterials.Id INNER JOIN
dbo.MaterialDescriptions ON dbo.Materials.MaterialDescriptionId = dbo.MaterialDescriptions.Id INNER JOIN
dbo.MaterialScopes ON dbo.MaterialDescriptions.MaterialScopeId = dbo.MaterialScopes.Id INNER JOIN
dbo.MaterialScopeObjectNames ON dbo.MaterialDescriptions.MaterialScopeObjectId = dbo.MaterialScopeObjectNames.Id
I have a query that is working for the most part until I had to add the inner select for "Trainers".
As you can see in the code below, I am trying to get all of the trainers for each of the segment ID's.
I am getting an error on the first inner selects where clause WHERE trn.segmentID = tes.teSegmentID saying that tes.teSegmentID is not defined.
Is there another way to approach this query in order to get the trainers like I am trying to accomplish?
SELECT *,
(SELECT e2.[FirstName] AS trainerFirst,
e2.[LastName] AS trainerLast
FROM BS_Training_Trainers AS trn
LEFT OUTER JOIN
employeeTable AS e2
ON trn.trainerEmpID = e2.EmpID
WHERE trn.segmentID = tes.teSegmentID
FOR XML PATH ('trainer'), TYPE, ELEMENTS, ROOT ('trainers'))
FROM dbo.BS_TrainingEvents AS a
WHERE a.trainingEventID IN (SELECT tes.trainingEventID
FROM dbo.BS_TrainingEvent_Segments AS tes
INNER JOIN
dbo.BS_TrainingEvent_SegmentDetails AS tesd
ON tesd.segmentID = tes.teSegmentID
INNER JOIN
dbo.BS_LocaleCodes AS locale
ON locale.localeID = tesd.localeID
WHERE locale.location = 'Baltimore');
It seems like you're taking the scenic route towards this:
SELECT a.*,
X.[FirstName],
X.[LastName]
FROM dbo.BS_TrainingEvents AS a
LEFT OUTER JOIN (SELECT e2.[FirstName], e2.[LastName], locale.location FROM dbo.BS_TrainingEvent_Segments AS tes
INNER JOIN dbo.BS_Training_Trainers AS trn ON trn.segmentID = tes.teSegmentID
INNER JOIN dbo.BS_TrainingEvent_SegmentDetails AS tesd ON tesd.segmentID = tes.teSegmentID
INNER JOIN dbo.BS_LocaleCodes AS locale ON locale.localeID = tesd.localeID
LEFT OUTER JOIN employeeTable AS e2 ON trn.trainerEmpID = e2.EmpID) AS X ON a.trainingEventID = X.trainingEventID
WHERE X.location = 'Baltimore';
Not sure if I got all those joins right, it was hard to decode from all the nesting you have going on.
If I have guessed table relationships from their names correctly, the only way to solve this is to reference the same filtering condition twice: first, in the XML generation part, and second in the outer level of the query:
with cte as (
select distinct tes.trainingEventID, tes.teSegmentID
from dbo.BS_TrainingEvent_Segments AS tes
INNER JOIN dbo.BS_TrainingEvent_SegmentDetails AS tesd ON tesd.segmentID = tes.teSegmentID
INNER JOIN dbo.BS_LocaleCodes AS locale ON locale.localeID = tesd.localeID
WHERE locale.location = 'Baltimore'
)
SELECT a.*, (
SELECT e2.[FirstName] AS trainerFirst, e2.[LastName] AS trainerLast
FROM BS_Training_Trainers AS trn
LEFT OUTER JOIN employeeTable AS e2 ON trn.trainerEmpID = e2.EmpID
inner join cte c on trn.segmentID = c.teSegmentID
FOR XML PATH ('trainer'), TYPE, ELEMENTS, ROOT ('trainers')
)
FROM dbo.BS_TrainingEvents AS a
where exists (select 0 from cte c where c.testrainingEventID = a.trainingEventID);
It's difficult to tell whether this is completely correct, of course, but I hope you get the idea.
Oh yes, and if you would have an event with multiple Baltimore segments, you will never be able to tell which trainer takes which one. But you can always add more data into XML to resolve this.
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.
