Left Join Not Returning Rows
Nov 3, 2005
SELECT
[tblSections].[pageTitle],
[tblSections].[sectionURL],
[tblSectionContents].[articleID],
[tblSectionContents].[fileID],
[tblSectionContents].[linkID],
[tblCopy].[copyText],
[tblFiles].[fileName],
[tblFiles].[fileCaption],
[tblGroupings].[grouping],
[tblLinks].[linkURL]
FROM [tblSections]
LEFT JOIN [tblSectionContents] ON [tblSectionContents].[sectionID] = [tblSections].[id]
LEFT JOIN [tblCopy] ON [tblSectionContents].[articleID] = [tblCopy].[id]
LEFT JOIN [tblFiles] ON [tblSectionContents].[fileID] = [tblFiles].[id]
LEFT JOIN [tblGroupings] ON [tblFiles].[groupingID] = [tblGroupings].[id]
LEFT JOIN [tblLinks] ON [tblSectionContents].[linkID] = [tblLinks].[id]
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 :)

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

How to return only non matching left join records. Currently I am doing a traffic management database to learn sql.
I am checking for all parishes with no associated drivers. Currently I only have 2 of such.
The regular left join
select parish.name, driver.fname from parish left join driver on driver.parish=parish.name
Returns the all the names of the parishes and the first name of the associated drive, followed by the matches, however the two parishes with no matches have null for the first name.

I have a SELECT Statement that I am using that is pulling from two tables. There won't always be results in the second table so I made a LEFT OUTER JOIN. The problem I am having is that I need to have three conditions in there:WHERE (employee.emp_id = @emp_id) AND (request.requested_time_taken = 'FALSE') AND (request.request_end_date >= GETDATE()))The two conditions from the request table are causing the entire query to return NULL as the value. I need help trying get a value whether or not there are any results in the request table.Here is the full select statement:SELECT (SELECT SUM(ISNULL(request.request_duration, '0')) AS Expr1
FROM employee LEFT OUTER JOIN
request AS request ON employee.emp_id = request.emp_id
WHERE (employee.emp_id = @emp_id) AND (request.requested_time_taken = 'FALSE') AND (request.request_end_date >= GETDATE()))
AS dayspending
FROM employee AS employee_1 LEFT OUTER JOIN
request AS request_1 ON employee_1.emp_id = request_1.emp_id
WHERE (employee_1.emp_id = @emp_id)
GROUP BY employee_1.emp_id, employee_1.emp_begin_accrual, employee_1.emp_accrual_rate, employee_1.emp_fname, employee_1.emp_minitial,
employee_1.emp_lname

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

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 000-333 150 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

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.

I need to create a SQL view whichjoins a few tables, and I need to return an average for a particularcolumn where a second duplicate ID exists...Heres an example of how the results could be returned...ID | Name | Order No. | Value---+------+-----------+---------5 | test | 1234 | 35 | test2| 1234 | 45 | test3| 1234 | 35 | void | 1235 | 55 | void2| 1235 | 65 | void3| 1235 | 55 | void4| 1235 | 7ID is my main join which joins the tablesName is a unique nameOrder No is the same for the different names, I only need to return onerow with this order no, and the first name (the rest are irrelevant)Value is the field which I wish to return as an average of all 3, 4 orhowever many rows is returned and share the same order no. This iswhere I get totally lost as I am pretty new to SQL. Can anyone provideany help on how I would go about limiting this query to the uniqueorder no's and returning the average of the value field, and I can takeit from there with my own tables.Thanks for your helpstr8

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.

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]

Hi guys,
I'll appreciate any help with the following problem:
I need to retrieve data from 3 tables. 2 master tables and 1 transaction table.
1. Master table TBLOC contain 2 records :
rcd 1. S01
rcd 2. S02
2. Master table TBCODE contain 5 records:
rcd 1. C1
rcd 2. C2
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

Following is the query that I'm running:
create table a (id int, name varchar(10));
create table b(id int, sal int);
insert into a values(1,'John'),(1,'ken'),(2,'paul');
insert into b values(1,400),(1,500);
select *
from a
cross apply( select max(sal) as sal from b where b.id = a.id)b;
Below is the result for the same:
idname sal
1John500
1ken500
2paulNULL
Now I'm not sure why the record with ID 2 is coming using CROSS APPLY, shouldn't it be avoided in case of CROSS APPLY and only displayed when using OUTER APPLY.
One thing that I noticed was that if you remove the Aggregate function MAX then the record with ID 2 is not shown in the output. I'm running this query on SQL Server 2012.

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.

tblBasketConstituents
ID, ParentIndexID, ChildIndexID, Weight
121 20
223 80

412 50
As you can see the ParentIndexID and ChildIndexID fields refer to tblIndices.IndexID
I would like a stored procedure as follows:
show all index names and show the wights for the indexID you passed.
This is what I have so far and it is not correct yet. Not sure what the syntax should be.
alter PROCEDURE [dbo].[uspBasketIndices_Get]
@IndexIDint
AS
select
i.IndexID,
i.[Name],
bc.Weight
from
tblIndices as i left join tblBasketConstituents as bc on i.IndexID = bc.ParentIndexID
and i.IndexID = @IndexID

Any one know any facts and figures about maximum Left Joins allowed (or recommended) in one query?
I am running a MS SQL 2000 my database is full of relational data and most of my foreign keys (INT data type) are a Clustered Indexed, Usually I will only be pulling one record from collection of about a dozen tables, but the Database is expected to grow fast and become big.
Right now I have a Stored Proc that has eight(8) LEFT JOINs in it. My worry is that this query will kill me as the database approaches 50,000 records.

p.haircolor, p.eyecolor, p.complexion, p.bodybuilt, p.picture, p.dialectspoken,

from hremployees as e
inner join psdatacenter as d on e.empdcno = d.dcno
inner join pspersonaldata as p on e.empdcno = p.dcno
left join hrappempcharrefs as c on e.empdcno = c.empdcno
left join hrappempeducs as ed on e.empdcno = ed.empdcno
left join hrsetschools as sch on ed.schoolcode = sch.schcode
the above query gives a 77 records
if i ran "select * from hremployees" generates 60 records
i think the error is in the left joining.
hrappempcharrefs, hrappempeducs and hrsetschools must be left joined to hremployees.

Hello!
I need to write a query using left outer join and I'm having trouble with it.
I have 2 tables:customer and cust_info.
I want to pull all records from customer table and cust_info table even if there is no related data in cust_info table.
But I need one condition in this query:only records from customer table where cus_type in ("A","B","C").
I don't need all other types ("D","E").
So my query looks like this:
select customer.cus_name,customer.cus_address,customer.cu s_type,cus_info.status
from customer
left outer join cus_info ON customer.sxdat_pk = cus_info.sxdat_pk
and cus_type in ("A","B","C")
AND cus_info.cus_table = 'CUSTOMER'
The result should be like this:
cus_name cus_address cus_type status
Amoco 457 bent A new
Bingo 47 lone oak C NULL
Sears 1020 Magic dr. B exist
But my query pulls records for customers with type "D" and "E" that I'm trying to exclude from result.
Please help.
Thanks,

Hello everybody!!!
I have to left join 2 tables. The first consists of columns:id, description, descr_num.
The second table: id, descr_num, value.
I need to extract description from table1 where descr_num is in the range , say, 1-10.
LEFT JOIN
extract value from table2 ,descr_num should be in the same range. in table2 some values from (1,10) and desc_num could be not present.
BUT i want this left join to be limited as i said.
Is there any solution to this prob. without creating temp tables. Or actually can i do such a join?

Now I have a table with the table design as following :

1 Peter Null Null true
2 Juli 1, xxxx 2 true
3 Sam Null Null False
table cst_EmpType
intEmpType nvcEmployeeType
1 Free Enginner
2 Manager
3 Operator
To join the table but MUST follow the condition as bitActiv = TRUE:
select emp.nvcEmpName, emp.nvcEmpAddress, ety. nvcEmployeeType from cst_EmpProfile emp left join cst_EmpType on emp.intEmployeeTypee = ety.intEmpType and emp.bitActiv = 1.
But, the sql statement doesnt output the my expected result.
Because the data row return must be 1st and 2nd row as it bitActiv = true.
So, how's I going achieve what i want. tq.

Hi,
Iwant to make a left join between two tables connected with a specific field
but I also want to have some criteria on the right table.
I want to display all the rows from the first(left) table and only the rows from the secod (right) table that match the join and the criteria.
However If I have criteria on the second table the join behaves like an inner join displaying only the rows that exist in both tables.
In MS Access instead of the right table I use a query in which I enter the criteria and then I connect it with a left join in a new query in order to get the right results. How can I do itin MSSQLServer without using Views?
Must I use a subquery with Exists and what is the right syntax in order to achieve this?
Best Regards,
manolis Perrakis
