Multiple INNER JOIN SELECT query not returning data - sql-server

This is a stored procedure to select the full details of a wine.
It takes as a parameter a storage location ID.
This builds properly and is similar in structure to many sp's I have written that work,
however it returns no data. Is there something I am missing?
CREATE PROCEDURE [sp_retrieveInventory_Full]
(
#StorageLocationID [int]
)
AS
BEGIN
SELECT [WineName],
[RackID],
[RackColumn],
[RackRow],
[WineTypeID],
[WineVarietyID],
[VintnerName],
[dbo].[Vintner].[Country],
[dbo].[Vintner].[StateProvince],
[dbo].[Vintner].[Region],
[VendorName],
[Vintage],
[PurchaseDate],
[PurchasePrice],
[BottleSizeID],
[ABV],
[DrinkByDate],
[FoodType],
[TastingNotes],
[RatedBy],
[RatingScore]
FROM [dbo].[StorageLocation]
INNER JOIN [dbo].[Wine]
ON [dbo].[StorageLocation].[WineID] = [dbo].[Wine].[WineID]
INNER JOIN [dbo].[Vintner]
ON [dbo].[Vintner].[VintnerID] = [dbo].[Wine].[VintnerID]
INNER JOIN [dbo].[Vendor]
ON [dbo].[Vendor].[VendorID] = [dbo].[Wine].[VendorID]
INNER JOIN [dbo].[Pairing]
ON [dbo].[Pairing].[PairingID] = [dbo].[Wine].[PairingID]
INNER JOIN [dbo].[Rating]
ON [dbo].[Rating].[RatingID] = [dbo].[Wine].[RatingID]
WHERE [dbo].[StorageLocation].[StorageLocationID] = #storageLocationID
END
GO

When a query reruns no result it's because no records exists that satisfy the conditions in it's where clause, or, in case of queries that contains inner joins, at least one of the joins on condition returns no records.
The easiest way to figure out what join is messing up your query is to start removing the joins one by one, but to do that, you have to first change the select clause.
What I like to do is this: Start with all the joins except the last one - see if it returns any records:
SELECT 1
FROM [dbo].[StorageLocation]
INNER JOIN [dbo].[Wine]
ON [dbo].[StorageLocation].[WineID] = [dbo].[Wine].[WineID]
INNER JOIN [dbo].[Vintner]
ON [dbo].[Vintner].[VintnerID] = [dbo].[Wine].[VintnerID]
INNER JOIN [dbo].[Vendor]
ON [dbo].[Vendor].[VendorID] = [dbo].[Wine].[VendorID]
INNER JOIN [dbo].[Pairing]
ON [dbo].[Pairing].[PairingID] = [dbo].[Wine].[PairingID]
-- INNER JOIN [dbo].[Rating]
-- ON [dbo].[Rating].[RatingID] = [dbo].[Wine].[RatingID]
WHERE [dbo].[StorageLocation].[StorageLocationID] = #storageLocationID
If not, comment out the next join and run the query again. Rinse and repeat.
Please note, however, that there might be more than one inner join that prevents the query from returning records.

SQL Server - using Over/Partition By in complex query

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:
SELECT
Main.MfgOrder.OrderNumber,
Main.MfgOrder.DesignBOMID,
Main.Design_Plant.PlantID,
Main.MfgOrder_Operation.OrderOpID,
Main.MfgOrder_Operation.DesignOpID,
Main.MfgOrder_Operation.OpSeq,
Main.MfgOrder_Operation.Description,
Main.MfgOrder_Operation.CompletionStatus,
Main.MfgOrder__Shift.OrderShiftID,
Main.MfgOrder__Shift.WorkCenterMachineID,
Main.MfgOrder___Event.OrderEventID,
Main.MfgOrder____Reel.OrderReelID,
Main.MfgOrder____Reel.ReelNumber,
Main.MfgOrder____Reel.Location,
Main.MfgOrder____Reel.Test_Status AS Test_Status_Reel,
Main.MfgOrder____Reel.Test_Disposition AS Test_Disposition_Reel,
Main.MfgOrder____Reel.LabReleased,
Main.MfgOrder____Reel.ShipReelsBypassSet,
Main.MfgOrder_____Length.OrderLengthID,
Main.MfgOrder_____Length.LengthType,
Main.MfgOrder_____Length.LocationOnReel,
Main.MfgOrder_____Length.LocationOnLength,
Main.MfgOrder_____Length.TrialNumber,
Main.MfgOrder_____Length.SampleNumber,
Main.MfgOrder_____Length.PrintNumber,
Main.MfgOrder_____Length.Test_Status AS Test_Status_Length,
Main.MfgOrder_____Length.Test_Category,
Main.MfgOrder_____Length.Test_Disposition AS Test_Disposition_Length,
Main.MfgOrder_____Length.SampleSubmittedBy,
Main.MfgOrder_____Length.SampleSubmittedDate,
Main.MfgOrder_____Length.BypassTesting,
Main.MfgOrder_____Length_OperatorQty.Sample1Destination,
Main.MfgOrder_____Length_OperatorQty.Sample2Destination,
Main.MfgOrder_____Length_OperatorQty.Sample3Destination,
Main.MfgOrder______Component.OrderComponentID,
Main.MfgOrder______Component.DesignComponentID,
Main.MfgOrder______Component.ItemNo,
Main.MfgOrder_______Test.LabTestID,
Main.MfgOrder_______Test.OrderTestID,
Main.MfgOrder_______Test.TestComplete,
Main.MfgOrder_______Test.TestStatus,
Main.MfgOrder________Marker2.OrderMarkerID,
Master.Color.ColorName,
Master.LabTest.ExcludeFromPassFail,
CASE
WHEN Main.Design_Component.Component_Label IS NULL
THEN 'Unknown'
ELSE Main.Design_Component.Component_Label
END AS Component_Label
FROM
Main.MfgOrder
INNER JOIN
Main.Design__BOM ON Main.MfgOrder.DesignBOMID = Main.Design__BOM.DesignBOMID
INNER JOIN
Main.Design_Plant ON Main.Design__BOM.DesignPlantID = Main.Design_Plant.DesignPlantID
INNER JOIN
Main.MfgOrder_Operation ON Main.MfgOrder.OrderNumber = Main.MfgOrder_Operation.OrderNumber
INNER JOIN
Main.MfgOrder__Shift ON Main.MfgOrder_Operation.OrderOpID = Main.MfgOrder__Shift.OrderOpID
INNER JOIN
Main.MfgOrder___Event ON Main.MfgOrder__Shift.OrderShiftID = Main.MfgOrder___Event.OrderShiftID
INNER JOIN
Main.MfgOrder____Reel ON Main.MfgOrder___Event.OrderEventID = Main.MfgOrder____Reel.OrderEventID
INNER JOIN
Main.MfgOrder_____Length ON Main.MfgOrder____Reel.OrderReelID = Main.MfgOrder_____Length.OrderReelID
LEFT OUTER JOIN
Main.MfgOrder______Component ON Main.MfgOrder_____Length.OrderLengthID = Main.MfgOrder______Component.OrderLengthID
LEFT OUTER JOIN
Main.MfgOrder_______Test ON Main.MfgOrder______Component.OrderComponentID = Main.MfgOrder_______Test.OrderComponentID
LEFT OUTER JOIN
Main.MfgOrder________Marker2 ON Main.MfgOrder_______Test.OrderTestID = Main.MfgOrder________Marker2.OrderTestID
LEFT OUTER JOIN
Main.Design_Component ON Main.MfgOrder______Component.DesignComponentID = Main.Design_Component.DesignComponentID
LEFT OUTER JOIN
Master.Color ON Main.MfgOrder______Component.TapeColorID = Master.Color.ColorNumber
LEFT OUTER JOIN
Master.LabTest ON Main.MfgOrder_______Test.LabTestID = Master.LabTest.LabTestID
LEFT OUTER JOIN
Main.MfgOrder_____Length_OperatorQty ON Main.MfgOrder______Component.OrderLengthID = Main.MfgOrder_____Length_OperatorQty.OrderLengthID
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.

MS SQL Table Joins - Multiple Tables

I am new to MS SQL and am having trouble joining 4 tables within a query.
I am trying to join Orders, Order Lines, Client, and Picked tables to create a query to show quantity ordered and picked for a client. If I comment out the last inner join for Picked, I get the correct results. When I include the inner join for Picked the query returns results but data that should be in the Picked fields is NULL. One order line can have 1 or more Picked lines.
SELECT W_Warehouse, OH.OrderID, OH.RequiredDate, C.Client, OL.LineNbr, OL.QtyOrd, P.QtyPick
FROM Order
INNER JOIN Warehouse on Order.OH_WHS = Warehouse.W_PK
INNER JOIN Client on Order.O_Client = Client.C_PK
INNER JOIN OrderLine on Order.O_PK = OrderLine.OL_PK
INNER JOIN Picked on OrderLine.O_PK = Picked.P_PK
WHERE C.CLIENT = 'WENDYS'
Without knowing the data in the tables it is difficult to answer precisely.
But as you say you have 1+ rows in the Picked table, you probably want to do aggregation with GROUP BY and SUM()
Maybe this is what you're looking for:
SELECT
W.W_Warehouse,
OH.OrderID,
OH.RequiredDate,
C.Client,
OL.LineNbr,
OL.QtyOrd,
P.QtyPick
FROM
Order OH
INNER JOIN Warehouse W on OH.OH_WHS = W.W_PK
INNER JOIN Client C on OH.O_Client = C.C_PK
INNER JOIN OrderLine OL on OH.O_PK = OL.OL_PK
CROSS APPLY (
select sum(QtyPick) as QtyPick
from Picked P
where OL.O_PK = P.P_PK
) P
WHERE
C.CLIENT = 'WENDYS'
It calculates the sum of QtyPick separately so it doesn't increase the number of lines in the result.

How to join one select with another when the first one not always returns a value for specific row?

I have a complex query to retrieve some results:
EDITED QUERY (added the UNION ALL):
SELECT t.*
FROM (
SELECT
dbo.Intervencao.INT_Processo, analista,
ETS.ETS_Sigla, ATC.ATC_Sigla, PAT.PAT_Sigla, dbo.Assunto.SNT_Peso,
CASE
WHEN ETS.ETS_Sigla = 'PE' AND (PAT.PAT_Sigla = 'LIB' OR PAT.PAT_Sigla = 'LBR') THEN (0.3*SNT_Peso)
WHEN ETS.ETS_Sigla = 'CD' THEN (0.3*SNT_Peso)*0.3
ELSE SNT_Peso
END AS PESOAREA,
CASE
WHEN a.max_TEA_FimTarefa IS NULL THEN a.max_TEA_InicioTarefa
ELSE a.max_TEA_FimTarefa
END AS DATA_INICIO_TERMINO,
ROW_NUMBER() OVER (PARTITION BY ATC.ATC_Sigla, a.SRV_Id ORDER BY TEA_FimTarefa DESC) AS seqnum
FROM dbo.Tarefa AS t
INNER JOIN (
SELECT
MAX(dbo.TarefaEtapaAreaTecnica.TEA_InicioTarefa) AS max_TEA_InicioTarefa,
MAX (dbo.TarefaEtapaAreaTecnica.TEA_FimTarefa) AS max_TEA_FimTarefa,
dbo.Pessoa.PFJ_Descri AS analista, dbo.AreaTecnica.ATC_Id, dbo.Tarefa.SRV_Id
FROM dbo.TarefaEtapaAreaTecnica
LEFT JOIN dbo.Tarefa ON dbo.TarefaEtapaAreaTecnica.TRF_Id = dbo.Tarefa.TRF_Id
LEFT JOIN dbo.AreaTecnica ON dbo.TarefaEtapaAreaTecnica.ATC_Id = dbo.AreaTecnica.ATC_Id
LEFT JOIN dbo.ServicoAreaTecnica ON dbo.TarefaEtapaAreaTecnica.ATC_Id = dbo.ServicoAreaTecnica.ATC_Id
AND dbo.Tarefa.SRV_Id = dbo.ServicoAreaTecnica.SRV_Id
INNER JOIN dbo.Pessoa ON dbo.Pessoa.PFJ_Id = dbo.ServicoAreaTecnica.PFJ_Id_Analista
GROUP BY dbo.AreaTecnica.ATC_Id, dbo.Tarefa.SRV_Id, dbo.Pessoa.PFJ_Descri
) AS a ON t.SRV_Id = a.SRV_Id
INNER JOIN dbo.TarefaEtapaAreaTecnica AS TarefaEtapaAreaTecnica_1 ON
t.TRF_Id = TarefaEtapaAreaTecnica_1.TRF_Id
AND a.ATC_Id = TarefaEtapaAreaTecnica_1.ATC_Id
AND a.max_TEA_InicioTarefa = TarefaEtapaAreaTecnica_1.TEA_InicioTarefa
LEFT JOIN AreaTecnica ATC ON TarefaEtapaAreaTecnica_1.ATC_Id = ATC.ATC_Id
LEFT JOIN Etapa ETS ON TarefaEtapaAreaTecnica_1.ETS_Id = ETS.ETS_Id
LEFT JOIN ParecerTipo PAT ON TarefaEtapaAreaTecnica_1.PAT_Id = PAT.PAT_Id
LEFT OUTER JOIN dbo.Servico ON a.SRV_Id = dbo.Servico.SRV_Id
INNER JOIN dbo.Intervencao ON dbo.Servico.INT_Id = dbo.Intervencao.INT_Id
LEFT JOIN dbo.Assunto ON dbo.Servico.SNT_Id = dbo.Assunto.SNT_Id
) t
The result is following:
It works good, the problem is that I was asked that if when a row is not present on this query, it must contain values from another table (ServicoAreaTecnica), so I got this query for the other table based on crucial information of the first query. So if I UNION ALL I get this:
Query1 +
UNION ALL
SELECT INN.INT_Processo,
PES.PFJ_Descri,
NULL, --ETS.ETS_Sigla,
ART.ATC_Sigla,
NULL ,--PAT.PAT_Sigla,
ASS.SNT_Peso,
NULL, --PESOAREA
NULL, --DATA_INICIO_TERMINO
NULL --seqnum
FROM dbo.ServicoAreaTecnica AS SAT
INNER JOIN dbo.AreaTecnica AS ART ON ART.ATC_Id = SAT.ATC_Id
INNER JOIN dbo.Servico AS SER ON SER.SRV_Id = SAT.SRV_Id
INNER JOIN dbo.Assunto AS ASS ON ASS.SNT_Id = SER.SNT_Id
INNER JOIN dbo.Intervencao AS INN ON INN.INT_Id = SER.INT_Id
INNER JOIN dbo.Pessoa AS PES ON PES.PFJ_Id = SAT.PFJ_Id_Analista
The result is following:
So what I want to do is to remove row number 1 because row number 2 exists on the first query, I think I got it explained better this time. The result should be only row number 1, row number 2 would appear only if query 1 doesn't retrieve a row for that particular INN.INT_Processo.
Thanks!
Ok, there are two ways to reduce your record set. Given that you've already written the code to produce the table with the extra rows, it might be easiest to just add code to reduce that:
Select * from
(Select *
, Row_Number() over
(partition by IntProcesso, Analista order by ISNULL(seqnum, 0) desc) as RN
from MyResults) a
where RN = 1
This will assign row_number 1 to any rows that came from your first query, or to any rows from the second query that do not have matches in the first query, then filter out extra rows.
You could also use outer joins with isnull or coalesce, as others have suggested. Something like this:
Select ISNULL(a.IntProcesso, b.IntProcesso) as IntProcesso
, ISNULL(a.Analista, b.Analista) as Analista
, ISNULL(a.ETSsigla, b.ETSsigla) as ETSsigla
[repeat for the rest of your columns]
from Table1 a
full outer join Table2 b
on a.IntProcesso = b.IntProcesso and a.Analista = b.Analista
Your code is hard to read, because of the lengthy names of everything (and to be honest, the fact that they're in a language I don't speak also makes it a lot harder).
But how about: replacing your INNER JOINs with LEFT JOINs, adding more LEFT JOINs to draw in the alternative tables, and introducing ISNULL clauses for each variable you want in the results?
If you do something like ... Query1 Right Join Query2 On ... that should get only the rows in Query2 that don't appear in Query 1.

Inner Join and Left Join in same sql query

I'm trying to perform inner join and then left join in same sql query.
But the left join is not working. It is not showing the null values
I've two tables EVENT_INVITATIONS and USERINFO which has 2 records when joined.
so, the join query goes like this :
select * from [UandMePROD].[dbo].EVENT_INVITATIONS EI
join [UandMePROD].[dbo].USERINFO UI on EI.USER_ID = UI.USER_ID and EI.EVENT_ID=11033
It gives out 2 records.
So, I'm performing a left join with another table CLIENT_CONTACTS which has only 1 matching record in it.
So, actually it should show the null value to the unmatched record. but it is not showing the second record. It is showing only 1 record which is matched(join)
My failed sql query :
select * from [UandMePROD].[dbo].EVENT_INVITATIONS EI
join [UandMePROD].[dbo].USERINFO UI on EI.USER_ID = UI.USER_ID
left join CLIENT_CONTACTS CC on UI.MOBILENO=CC.MOBILE_NUMBER
where cc.CLIENT_ID=20111 and EI.EVENT_ID=11033
can you please tell me where I'm doing mistake?
I need the 2 records.
Since you are doing a left join, cc.CLIENT_ID is null for all the values which only exist in CLIENT_CONTACTS and your where clause Where cc.CLIENT_ID = 20111
converts your LEFT JOIN into INNER JOIN. Adding this filter in ON clause solves the issue.
select *
from [UandMePROD].[dbo].EVENT_INVITATIONS EI
inner join [UandMePROD].[dbo].USERINFO UI on EI.[USER_ID] = UI.[USER_ID]
left join CLIENT_CONTACTS CC on UI.MOBILENO = CC.MOBILE_NUMBER
and cc.CLIENT_ID = 20111
where EI.EVENT_ID=11033
You should not specify EI.EVENT_ID on WHERE clause. Those limit your results after the join. You should specify EI.EVENT_ID in an ON clause.
select * from [UandMePROD].[dbo].EVENT_INVITATIONS EI join [UandMePROD].[dbo].USERINFO UI on EI.USER_ID = UI.USER_ID AND (EI.EVENT_ID=11033 or EI.EVENT_ID is null) left join CLIENT_CONTACTS CC on UI.MOBILENO=CC.MOBILE_NUMBER where cc.CLIENT_ID=20111
Providing some suggestions,since it is not possible to say what is happening with out table data
Left join should show null values from output of first inner join eventhough there are no mobile number matches,so try removing where condition and see if you are getting any result

mssql and dynamic column from another table

i have this select statement:
select * from folder
inner join subprops on folder.id = subprop.id
inner join props on props.id = subprops.id
inner join products on product.feature = subprop.val
product.feature has values for example 300,301
and subprop.val has these values as well
i have column props.colname
and i want to make the third inner join dynamicly by the props.colname value
with some kind of eval() or anything else
inner join products on product.eval(props.colname) = subprop.val
can you think about anything? i can't find solution for that without dynamic statement or loop - that i don't want to do
