Transact SQL :: Left Join Returns Too Many Rows Vertically
Jun 18, 2015
I have a query that based 2 tables. I wrote a query with a left join on the base table but the result set returns multiple rows for each occurrence in the second table because of the left join. I want but to return all records from on table A and only matching records from table B which id but I would wan tit to keep return them vertically as the because it make it difficult to read when put in a spreadsheet. It want it to return the values horizontally so the rows are not increasing for each occurrence on table b.

Why does this right join return the same results as using a left (or even a full join)?There are 470 records in Account, and there are 1611 records in Contact. But any join returns 793 records.
select Contact.firstname, Contact.lastname, Account.[Account Name]
from Contact
right join Account
on Contact.[Account Name] = Account.[Account Name]
where Contact.[Account Name] = Account.[Account Name]

I am using stored procedure to load gridview but problem is that i am not getting all rows from first table[ Subject] on applying conditions on second table[ Faculty_Subject table] ,as you can see below if i apply condition :-
Faculty_Subject.Class_Id=@Class_Id
Then i don't get all subjects from subject table, how this can be achieved.
Sql Code:-
GO
ALTER Proc [dbo].[SP_Get_Subjects_Faculty_Details]

I have a query which is returning a different result set when it is run against identical tables in 2 different environments.
The query is like:
Select
F.LicenseeID, IsSpecialLicensee
from FactTable F
left join View_SpecialLicensee SL on F.LicenseeID = SL.LicenseeID
The Create Statement for the view is like
Create View [dbo].[View_SpecialLicensee]
as
Select LicenseeID, LicenseeName, IsSpecialLicensee = 1
from DimensionLicensee
where LicenseeName like '%ibm%'
or LicenseeName like '%cisco%'
or LicenseeName like '%hp%'
In my test environment, I get the query result I expected:
LicenseeID, IsSpecialLicensee
1 , 1 - (where LicenseeName = 'IBM')
2, null - (where LicenseeName = 'Juniper')
3, 1 - (where LicenseeName = 'Cisco')
4, null - (where LicenseeName = 'Microsoft')
5, null - (where LicenseeName = 'Oracle')
6, null - (where LicenseeName = 'Apple')
In my production environment, I get the following query result:
1 , 1 - (where LicenseeName = 'IBM')
2, 1 - (where LicenseeName = 'Juniper')
3, 1 - (where LicenseeName = 'Cisco')
4, 1 - (where LicenseeName = 'Microsoft')
5, 1 - (where LicenseeName = 'Oracle')
6, 1 - (where LicenseeName = 'Apple')
Ideas as to what changed gratefully received.
FYI the production environment which returned the 2nd dataset is SQL2000, I have got the result I expected in both SQL2000 and SQL2005 development environments.

I was writing a query using both left outer join and inner join. And the query was ....
SELECT
S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname
FROM
Production.Suppliers AS S LEFT OUTER JOIN
(Production.Products AS P
INNER JOIN Production.Categories AS C
[code]....
However ,the result that i got was correct.But when i did the same query using the left outer join in both the cases
i.e..
SELECT
S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname
FROM
Production.Suppliers AS S LEFT OUTER JOIN
(Production.Products AS P
LEFT OUTER JOIN Production.Categories AS C
ON C.categoryid = P.categoryid)
ON
S.supplierid = P.supplierid
WHERE
S.country = N'Japan';
The result i got was same,i.e
supplier country productid productname unitprice categorynameSupplier QOVFD Japan 9 Product AOZBW 97.00 Meat/PoultrySupplier QOVFD Japan 10 Product YHXGE 31.00 SeafoodSupplier QOVFD Japan 74 Product BKAZJ 10.00 ProduceSupplier QWUSF Japan 13 Product POXFU 6.00 SeafoodSupplier QWUSF Japan 14 Product PWCJB 23.25 ProduceSupplier QWUSF Japan 15 Product KSZOI 15.50 CondimentsSupplier XYZ Japan NULL NULL NULL NULLSupplier XYZ Japan NULL NULL NULL NULL
and this time also i got the same result.My question is that is there any specific reason to use inner join when join the third table and not the left outer join.

Hi all,
I am trying to build a association table (t2) to store a list of users
have viewed an item in my records table (t1). My goal is to send the
UserID parameter to the query and return to the user a read / not read
marker from the query so I can handle the read ones differently in my
.net code. The problem is that I cannot work out how to return anything
but the read data to the client. So far my stored proc looks like this
DECLARE @UserID AS Int -- FOR TESTING
SET @UserID = 219 -- FOR TESTING
SELECT t1.strTitle, t1.MemoID, Count(t2.UserID) AS ReadCount,t2.UserID
FROM t1
LEFT OUTER JOIN
t2 ON t1.MemoID = t2.MemoID
WHERE t2.UserID = @UserID
GROUP BY t1.MemoID, t1.strTitle,t2.UserID
It works fine but only returns those records from t1 that are read. I
need to return the records with null values also! I may have built the
assoc table wrong and would really appreciate some pointers on what I
am doing wrong. (assoc table has rID, MemoID and UserID columns)
Please help!
Many thanks

I have the following query:
select sq.*, p.numero, p.nombre
from paf p right outer join dbo.GetListOfSquaresForShippingLot(@lot) sq on sq.number = p.numero and sq.version = p.numero
The @lot parameter is declared at the top ( declare @lot int; set @lot = 1; ). GetListOfSquaresForShippingLot is a CLR TVF coded in C#. The TVF queries a XML field in the database and returns nodes as rows, and this is completed with information from a table.
If I run a query with the TVF only, it returns data; but if I try to join the TVF with a table, it returns empty, even when I'm expecting matches. I thought the problem was the data from the TVF was been streamed and that's why it could not be joined with the data from the table.
I tried to solve that problem by creating a T-SQL multiline TVF that is supposed to generate a temporary table. This didn't fix the problem.
What can I do? Does anybody know if I can force the TVF to render its data somewhere so the JOIN works? I was thinking a rowset function could help, but I just can't figure out how.
PLEASE HELP!!!!
Let me know if you want the code for the CLR TVF. This is the code for the T-SQL TVF:
CREATE FUNCTION [dbo].[GetTabListOfSquaresForShippingLot]
(
@ShippingLot int
)
RETURNS
@result TABLE
(
Number int, Version int, Position smallint,
SubModel smallint, Quantity smallint,
SquareId nvarchar(5),
ParentSquareId nvarchar(5),
IsSash smallint,
IsGlazingBead smallint,
Width float,
Height float,
GlassNumber smallint,
GlassWidth float,
GlassHeight float
)
AS
BEGIN
INSERT INTO @result
SELECT *
FROM dbo.GetListOfSquaresForShippingLot(@ShippingLot)
RETURN
END

WHERE [tblSections].[id]=2
ORDER BY
[tblSectionContents].[articleID],
[tblSectionContents].[fileID],
[tblSectionContents].[linkID]
If I pass it the ID of a section that has files or copy or [stuff in other tables] attached, then I get a result set that makes sense.
But if I pass it a section ID that doesn't reference any other content tables (ie: the section just has a title and a link URL), I don't get anything back.
Shouldn't it should still get me the fields from the row in tblSections that matches the ID I'm passing it?
How can I make it so that it does?
Thanks :)

Here is my query which returns multiple rows
SELECT
R.name, R.age,R.DOB,
ISNULL(D.Doc1,'NA') AS doc1,
ISNULL(C.Doc2,'NA') AS doc2
FROM
REQ R
inner join RES S ON R.Request_Id=S.Request_Id
inner join RES1 D ON D.Response_Id=S.Response_Id
inner join REQ1 C ON C.Request_Id=R.Request_Id
select * from RES1 where Response_Id = 111 -- return 3
select * from REQ1 where Request_Id = 222 --- returns 2
So at last inner join retuns 3*2 = 6 records , which is wrong here and i want to show 3 records in doc1 row and 2 records in doc 2 rows ...

My tables look like this:
Users //
table
UserID // pk
UserName // varchar
UserFamilyName // varchar
User_Friends //
table
FriendsID // pk
UserID // fk
FamilyName // varchar
MY query:
SELECT
U.UserFamilyName, F.FamilyName
FROM
Users U LEFT
JOIN User_Friends
F ON U.UserID =
F.UserID
WHERE

How do I adjust my query to select just the very first record from Users_friends, I want only the top first one.And if there are no friends how can I return an empty string instead of Null.

Anyone know why using
SELECT *
FROM a LEFT OUTER JOIN b
ON a.id = b.id
instead of
SELECT *
FROM a LEFT JOIN b
ON a.id = b.id
generates a different execution plan?
My query is more complex, but when I change "LEFT OUTER JOIN" to "LEFT JOIN" I get a different execution plan, which is absolutely baffling me! Especially considering everything I know and was able to research essentially said the "OUTER" is implied in "LEFT JOIN".
Any enlightenment is very appreciated.
Thanks

Hello All.
I am struggling with the below join block in my stored procedure.
I can't seem to get the duplicate row problem to go away. It seems that SQL is treating each new instance of an email address as reason to create a new row despite the UNIONs.
I understand that if I am using UNION, using DISTINCT is redundant and will not solve the duplicate row problem.
Primary Keys: none of the email address columns are primary keys. Each table has an incrementing ID column that serves
as the primary key.
I am guessing I am encountering this problem because of how
I have structured my Join statements? Is it possible to offer advice without a deeper understanding of my data model or
do you need more information?
Thanks for any tips.
Code:
select emailAddress from Users union
select user_name from PersonalPhotos union
select email_address from EditProfile union
select email_address from SavedSearches union
select distinct email_address from UserPrecedence union
select email_address from LastLogin) drv
Left Join Users tab1 on (drv.emailAddress = tab1.emailAddress)
Inner Join UserPrecedence tab5 on tab5.UserID=tab1.UserID
Left Join PersonalPhotos tab2 on (drv.emailAddress = tab2.user_name)
Left Join LastLogin tab4 on (drv.emailAddress = tab4.email_address)
Left Join EditProfile tab3 on (drv.emailAddress = tab3.email_address)
Left Join SavedSearches tab6 on (drv.emailAddress = tab6.email_address

This is what I want my results to look like
invoice wbs1 wbs2 amount
8060 000-333 500 0
8060 000-333 100 0
8060 000-333 140 0
8060 000-333 150 4335

8267 000-333 140 547.50
8267 000-333 150 2000
8267 000-333 160 5000
This is what I have so far:
SELECT PR.WBS1, PR.WBS2, ledgerar.invoice, SUM(CASE WHEN ledgerar.transtype = 'in' AND ledgerar.period = '200405' THEN ledgerar.amount * - 1 END) AS amount
FROM PR LEFT OUTER JOIN
LedgerAR ON LedgerAR.WBS1 = PR.WBS1 AND LedgerAR.WBS2 = PR.WBS2 AND LedgerAR.WBS3 = PR.WBS3
WHERE (LedgerAR.wbs1 = '001-333') AND ledgerar.period = '200405'
GROUP BY pr.wbs1, pr.wbs2, ledgerar.invoice
the above query gives me the following results:
invoice wbs1 wbs2 amount
8060 000-333 100 0
8060 000-333 140 0
8060 000-333 160 4335
8267 000-333 100 1320
8267 000-333 140 20912.5
8267 000-333 150 8363
8267 000-333 160 2650
But I don't know how to get the query to display all of wbs2 whether it is null or not. So, for each invoice number there should be five records according to the wbs2 codes (500, 100, 140, 150, 160)
Does anyone know how to do this?
Thanks,
Laura

Need some join help...
Table 1 - Modules:
ID | Name
1 | A
2 | B
3 | C
Table 2 - CompanyModules
ModuleID | CompanyID
1 | 1
2 | 1
3 | 1
1 | 2
I'd like to return the following result set:
CompanyModules.CompanyID | Modules.Name | Present
1 | A | True
1 | B | True
1 | C | True
2 | A | True
2 | B | False
2 | C | False
What would be the query for this? Thanks.
Edit: This is the query I have tried:
select CompanyModules.CompanyID, Modules.Name, count(Modules.ID) as Present from
CompanyModules RIGHT outer Join Modules on CompanyModules.ModuleID = Modules.ID
group By CompanyModules.CompanyID, Modules.Name
Order by CompanyID
However, it only returns a partial result set:
CompanyModules.CompanyID | Modules.Name | Present
1 | A | 1
1 | B | 1
1 | C | 1
2 | A | 1

I have a query that returns material(items) that are used in an event on a certain day.
SELECT C.categoryName, count(I.itemID) AS InMission
from items as I
RIGHT JOIN Categories AS C on I.categoryID = C.categoryID
INNER JOIN LinkMissionItem as LM on I.itemID = LM.itemID
INNER JOIN Missions as M on LM.missionID = M.MissionID
where '2015/12/19' BETWEEN M.freightLeave and M.freightReturn AND isReturned = 0
GROUP BY C.categoryName, C.categoryID
ORDER BY C.categoryID
There are a total of 20 categories and I would like all the categories listed in the result even though there are no items booked in a mission. At the moment, I can only get the categories that have items in that category booked in a mission. I hoped that the RIGHT JOIN on the categories table would do the trick but it doesn't.

I am still new to SQL and I am having trouble obtaining the results I need from a query. I have worked on this command for some time and searched the internet but cannot seem to still get it correct.
I have a table called Patient. It's primary key is pat_id.
I have a second table called Coverage. It has no primary key. The foreign keys are pat_id, coverage_plan_id, and hosp_status.
I have a third table called Coverage_History. It has a primary key consisting of pat_id, hosp_status, copay_priority, and effective_from.
I want to get the pat_id and all the coverage information that is current. The coverage table contains specific insurance policy information. The coverage_history table will indicate the effective dates for the coverage. So the tables could contain something like this:
Patient (pat_id and lname)
P123 Monto
P124 Minto
P125 Dento
P126 Donto
Coverage (pat_id, coverage_plan_id, hosp_status, policy_num)
P123 MED1 OP A1499
P123 ACT4 OP H39B
P124 MED1 OP C90009
P124 RAC OP 99KKKK
P124 RAC OP 99KKKK
P124 MED1 OP C90009
P125 ARP OP G190
P126 BCB OP H88
Coverage_History (pat_id, hosp_status, copay_priority, effective_from, coverage_plan_id, effective_to)
P123 OP 1 20150102 MED1 NULL
P123 OP 2 20150102 ACT4 NULL
P124 OP 1 20150203 RAC 20150430
P124 OP 2 20150203 MED1 20150430
P124 OP 1 20150501 MED1 NULL
P124 OP 2 20150501 RAC NULL
P125 OP 1 20150801 ARP NULL
P126 OP 1 20150801 BCB 20160101
select p.pat_id, p.lname, ch.coverage_plan_id, ch.hosp_status, ch.effective_from, ch.effective_to, ch.copay_priority,
from patient p
left join
( coverage_history ch left join coverage c on ch.coverage_plan_id = c.coverage_plan_id and ch.patient_id = c.patient_id and
(ch.effective_to is NULL or ch.effective_to >= getdate()
)
) on ch.patient_id = p.patient_id
where ( ch.effective_to is NULL or ch.effective_to >= getdate() )
So I want to see:
P123 Monto MED1 OP 20150102 NULL 1
P123 Monto ACT4 OP 20150102 NULL 2
P124 Minto MED1 OP 20150501 NULL 1
P124 Minto RAC OP 20150501 NULL 2
P125 Dento ARP OP 20150801 NULL 1
P126 Donto BCB OP 20150801 20160101 1

We have a service that inserts some rows into a parent table (P) and child table (C). This operation is atomic and performed within a transaction.
We also have a service that queries these tables such that rows are (should only be) returned from P where there are no children for that parent.
The SQL that performs this is simplified below:
SELECT P.SomeCol
FROM P
LEFT OUTER JOIN C ON P.PKofP_Value = C.PkofP_Value
WHERE
C.PkofPValue IS NULL
AND P.SomeOtherCol=0
Our expectation is that the query service should only return rows from P where there are no rows in C.
However, this seems not to be the case, and occasionally we find that rows from P are returned where there are matching rows in C.
We are sure that the process that inserts rows into P and C does so within a single transaction.
We have traced this with SQLTrace and can see the txn stag and committing and all operations using the same transactionid within the transaction.
We are running the default isolation level committed.
In SQLTrace we can see the query process start, the inserter process start and complete and then the query process continue (after presumably being blocked).
So how can the query process "miss" the child rows and return the parent from the above query?
Is it possible that, in this isolation level, the inserter process can block the query process such that when the inserter process commits and when the query process continues it does not see the child rows inserted because they were inserted in the table/index "behind" where the query process has already read - some kind of phantom phenomenon?

The select command below will output one patient’s information in 1 row:
Patient id
Last name
First name
Address 1
OP Coverage Plan 1
OP Policy # 1
OP Coverage Plan 2
[code]...
This works great if there is at least one OP coverage. There are 3 tables in which to get information which are the patient table, the coverage table, and the coverage history table. The coverage table links to the patient table via pat_id and it tells me the patient's coverage plan and in which priority to bill. The coverage history table links to the patient and coverage table via patient id and coverage plan and it gives me the effective date.
select src.pat_id, lname, fname, addr1,
max(case when rn = 1 then src.coverage_plan_ end) as OP_Coverage1,
max(case when rn = 1 then src.policy_id end) as OP_Policy1,

1.) @Tab1 have multiple records for each ID
2.) @Tab2 also have multiple records for each ID
3.) Kind of Lef Outer join those tables with ID and take all records from @tab2 and only Max of date from @tab1 and order by ID and Date
Note: @Tab1 always have lesser dates than @tab2 for each ID
Tables looks like as follows
declare @tab1 table (id varchar(3), effDt Date, rate int)
insert into @tab1 values ('101','2013-12-01',5)
insert into @tab1 values ('101','2013-12-02',2)
insert into @tab1 values ('101','2013-12-03',52)

I need to left pad the column with 0 if it is less than 4 characters long and extract the first 2 characters on the left into a new column COUNTY_CODE.
How can I do that in transact SQL?

rcd 3. C3
rcd 4. C4
rcd 5. C5
3. Transaction table TBITEM contain 4 records which link to 2 master table:
rcd 1. S01, C1, CAR
rcd 2. S01, C4, TOY
rcd 3. S01, C5, KEY
rcd 4. S02, C2, CAR
I use Left Join & Right Join to retrieve result below (using non-ASNI method) but it doesn't work.
Right Join method:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A RIGHT JOIN TBCODE B ON A.CODE = B.CODE
RIGHT JOIN TBLOC C ON A.LOC = C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
When I use Non-ASNI method it work:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A, TBCODE B, TBLOC C
WHERE A.CODE =* B.CODE AND A.LOC =* C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
Result:
LOC CODE ITEM
-----------------------------
S01 C1 NULL
S01 C2 NULL
S01 C3 CAR
S01 C4 TOY
S01 C5 KEY
S02 C1 NULL
S02 C2 CAR
S02 C3 NULL
S02 C4 NULL
S02 C5 NULL
Please Help.
Thanks.

-- Why is the left table in a LEFT JOIN limited by the where clause on the right table?eg
DECLARE @LeftTable TABLE (LeftID INT NOT NULL IDENTITY(1, 1), LeftValue INT NULL)
INSERT @LeftTable (LeftValue)
VALUES (111)
INSERT @LeftTable (LeftValue)
VALUES (222)
[code]....

I'm trying to join 2 tables. I thought I was getting the correct results but it turns out I'm not.
My Query:
SELECT IVINVA, IVORDN, IVCSLN, IVRESR, IVCITM, CONVERT(varchar(12),CAST(IVIAMT as money),1) AS ExtPrice, CONVERT(varchar(12),CAST(IVPIVC as money),1) AS DistPrice, IVCSUM, IVQYCS, IVDESC, OIRESR, OIDPCT, CONVERT(varchar(12),CAST(IVPIVC - (OIDPCT / 100 * IVPIVC) as money),1) AS NetPrice FROM INVDET1_TBL LEFT JOIN ORDDIS_TBL ON ORDDIS_TBL.OIORDN = INVDET1_TBL.IVORDN AND ORDDIS_TBL.OIRESR = INVDET1_TBL.IVRESR WHERE IVORDN = '0859919' AND IVINVA = '00324024'
Basically, my problem lies in the seonc condition of the LEFT JOIN. I needed to set the two tables equal my item number, because in some situations I need that logic to get the correct result. It most other cases, that item column in the ORDDIS_TBL is NULL, thus giving me the wrong results. In that case, I would want the JOIN to only be ORDDIS_TBL.OIORDN = INVDET1_TBL.IVORDN, and not include the second part. Is there a way I can condition this with an If statement, If ORDDIS_TBL.OIRESR is Null then do this join, if not, then do this? I'm confused how to get the proper result here.

I need to make a left join from the freezefile f, to sped s, instead of having f.studentid = s.id in the where clause. Any help??
select f.studentid, f.studentname, f.sex, fs.mealstatus, s.except, s.lre, r.description, g.testid, g.scale_la, g.scale_ma, t.test_name, t.year
from freezefile f, fsapps fs, sped s, regtb_exception r, gqe_scores g, test_info t
where
f.type = 'ADM'
and
s.except = r.code
and
t.test_name = 'ISTEP'
and
t.year = 2004
and
g.testid = t.testid
and
f.studentid = fs.id
and
f.studentid = s.id
and
f.studentid = g.studentid
