Simple OUTER JOIN (I Thought)

Sep 11, 2007

Two tables:

Fruit
fruitID, fruitName

Basket
buyerID, fruitID

(ie. we can see which buyer has what fruit in their basket)

I simply want to display all available fruit and whether or not it's
in a specific persons' basket.

SELECT Fruit.fruitID, Fruit.fruitName, IsNull(buyerID, 0)
FROM Fruit INNER JOIN Basket ON Fruit.fruitID = Basket.fruitID
WHERE Basket.buyerID = 12

but this just gives me what's in buyer 12s' basket.

What am I doing wrong? Am I a basket case...

Simple Question Regarding Outer Join (was SQL Help)

Sep 4, 2006

Hi Everyone,

I have a simple question regarding outer join.

Please see the attached word file. It has screen shots of the query I am running. My first query shows the result where i have M.ReservationID = MA.MeetingID and it counts NoofRSVP (# of times the query runs). I have to modify first query in such a way that it returns records from eCDReservations table even if there is no matching MeetingID in MeetingAttendees table (means Null, see the result of 2nd query in attached file). So in my result for that case NoofRSVP column should show either Null or 0.

Simple Outer Join Question

May 31, 2007

Ok here is the situation. I have 2 tables.

Movies
MovieID Title Year
21 A Beautiful Mind 2002
22 Forrest Gump 1994
23 The English Patient 1999


Actors
ActorID MovieID Name
1 22 Tom Hanks
2 21 Russell Crowe
3 23 Ralph Fiennes
4 NULL Nachiket Mehta

Here is the SQL Query.

SELECT ActorID, Name, Title, Year FROM Actors LEFT OUTER JOIN Movies ON Actors.MovieID = Movies.MovieID

Now, I only want to show movies made in 1990's and display all 4 actors. If I put

WHERE Year < 2000

it won't show the fourth actor because he doesn't have any movies. I need to show all 4 actors here and NULL for movies if they don't have any.

Hope this makes sense. Thank you.

I Thought This Would Be Simple...

Jul 14, 2006

I had originally thought a full outer join would solve this, but alas I'm a roadblock. Perhaps it's because it's a Friday!

The goal is to create the most efficient query that will display results of the daily calls and sales as
this:

Date EmpID Calls Sales
7/1/2006 1 20 5
7/1/2006 2 25 7
7/1/2006 3 NULL 1
7/1/2006 4 10 NULL

The problem is a simple full outer join ends up ignoring EmpID 3 who has no Calls in t1, but I still want that row displayed in the results. Any ideas? TIA

create table t1 (Date smalldatetime, EmpID int, Calls int)

create table t2 (Date smalldatetime, EmpID int, Sales int)

insert into t1
values ('7/1/2006', 1, 20)

insert into t1
values ('7/1/2006', 2, 25)

insert into t1
values ('7/1/2006', 4, 10)

insert into t2
values ('7/1/2006', 1, 5)

insert into t2
values ('7/1/2006', 2, 7)

insert into t2
values ('7/1/2006', 3, 1)

SQL-92 Outer Join Vs T-SQL Outer Join (6.5 Or 7.0) - Test Script Included

Apr 26, 2002

Take the following scenario:

We have two tables that have somewhat of a parent-child relationship. We are trying to use a SQL-92 outer join that returns the same results as a TSQL *= outer join. The difficulty we are having is that some of the parent records do not have any corresponding child records, but we still want to see those parent records with 0 (zero) for the count. How can we accomplish this with a SQL-92 compliant join (if it is even possible)? In the query results below, we would like the first set of results.

Thanks in advance for any help.
-David Edelman

Test script below, followed by results
===========================================
create table parent (p_id int NOT NULL)
go
create table child (p_id int NOT NULL, c_type varchar(6) NULL)

insert parent values (3)
insert parent values (4)
insert parent values (5)
insert parent values (6)
insert parent values (7)
insert parent values (8)
insert parent values (9)
insert parent values (10)
go

insert child values (1, 'AAA')
insert child values (1, 'BBB')
insert child values (1, 'CCC')
insert child values (2, 'AAA')

insert child values (7, 'BBB')
insert child values (7, 'CCC')
insert child values (7, 'DDD')
insert child values (10, 'AAA')

from parent p, child c
where p.p_id *= c.p_id
and c.c_type in ('AAA', 'BBB')

select p.p_id, count(c.p_id) as num_rows
from parent p left outer join child c on p.p_id = c.p_id

Noob Alert! What I Thought Was A Real Simple Query...

Oct 22, 2007

Hi

I have a table which has the column [itemNumber] Which contains numbers from 000 to 999. I have another table which has the UPC data for given items
I am trying to get results from my query that will show me every number in the itemNumberSet table that does not already exist (in the substring) of the UPCcode column.

By using the query below i am able to retrieve the opposite, and it works by returning results that do exist in the UPCcode column. But I cannot seem to get it to do the opposite which is what i am after. I figured it would be as simple as using NOT IN but that returned 0 results.


SELECT itemNumber FROM itemNumberSet
WHERE itemNumber IN (select SUBSTRING(UPCcode, 9, 3) FROM itemUPCtable)
ORDER BY itemNumber


Thanks for any suggestions you might have.

LEFT OUTER JOIN Or RIGHT OUTER JOIN?

Nov 4, 2003

Hello

I've a table with these values:

Cod_Lingua - Des_Lingua
------------------------------
ITA Italian
GER German
ENG English
FRA French

and another table with product/description

ProductID - Cod_Lingua - Description
-------------------------------------------
1 ITA Mia Descrizione
1 ENG My Description

I've this SELECT:

SELECT Tab_Lingue.Cod_Lingua, Descrizioni_Lingua.Description
FROM Descrizioni_Lingua RIGHT OUTER JOIN Tab_Lingue ON Tab_Lingue.Cod_Lingua=Descrizioni_Lingua.Cod_Lingua
WHERE Descrizioni_Lingua.ProductID=1

I get these results:
ITA - Mia Descrizione
ENG - My Description

I don't want this. I'd like to have this:
ITA - Mia Descrizione
ENG - My Description
GER - (null)
FRA - (null)

How can I get the second result set?

Thanks for your support.

Transact SQL :: Difference Between Inner Join And Left Outer Join In Multi-table Joins?

Oct 8, 2015

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.

'Left Outer Merge Join' Failing To Join Valid Row

Aug 10, 2007

Scenario:

OLEDB source 1
SELECT ...
,[MANUAL DCD ID] <-- this column set to sort order = 1

OLEDB source 2
SELECT ...

These two tasks are followed immediately by a MERGE JOIN

All columns in source1 are ticked, all column in source2 are ticked, join key is shown above.
join type is left outer join (source 1 -> source 2)

result of source1 (..dcd column)

All other rows are joining as expected.
Why is it failing for this one row?

Merge Join (Full Outer Join) Never Finishes.

Jun 5, 2006

I have a merge join (full outer join) task in a data flow. The left input comes from a flat file source and then a script transformation which does some custom grouping. The right input comes from an oledb source. The script transformation output is asynchronous (SynchronousInputID=0). The left input has many more rows (200,000+) than the right input (2,500). I run it from VS 2005 by right-click/execute on the data flow task. The merge join remains yellow and the task never finishes. I do see a row count above the flat file destination that reaches a certain number and seems to get stuck there. When I test with a smaller file on the left it works OK. Any suggestions?

Self Join Outer Join Question

Oct 10, 2007

Given a table of building components e.g. floors, walls, etc, etc:

create table component_multiplier_table
(

system_code char(4),
system_component_code char(3),
function_code char(4),
component_multiplier dec(7,6)
)

Where function_code is the function of the area e.g. Auditorium, Classrom, etc, etc. And not all components are available for all functions e.g. Carpeting is available for Classrooms but not Power Plants or Warehouses.

I need to self join the above table to itself on system_code and system_component_code and find out which rows are missing from each side.

A query that I've been banging away at with no success is:

SELECT c1.*, c2.*
FROM [dbo].[component_multiplier_table] c1 FULL OUTER JOIN [dbo].[component_multiplier_table] c2
ON (c1.system_component_code = c2.system_component_code) AND (c1.[system_code] = c2.[system_code])
WHERE c1.function_code = '2120' AND c2.[function_code] = '2750' AND (c1.[system_code] IS NULL OR c2.system_code IS NULL);

I added the is null conditions, no joy. I've tried every flavor of outer join w/o success.

Could any T-SQL gurus out there help me figure out how to do this in a set before I start coding

DECLARE crsr CURSOR

Thanks.

Left Join Vs Left Outer Join Syntax Generates Different Execution Plans

Apr 16, 2008



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

OUTER JOIN

Jun 1, 2004

Oi! What follows is a hypothetical situation, but it is a totally analogous to a real problem Im having, but provides an easier model to understand.

Imagine that you have database-driven battleship game and its time to render the board. Also imagine that you have to render more than one board and that the ships are all the size of one point on the grid.

One sql result you need is a list of all the points on the grid, regardless of whether or not there is a ship on it. This will make rendering much easier for you, because you can simply look at the record index to determine if a ship is present. The data that is stored about the position of the ships consists of one record containing the grid index and ship name.

One possible way to retrieve this data is to build a table that you will not change which contains a record for each point on the grid. Is it possible to union or join on this table to retrieve a list of results that contain both unoccupied locations and occupied ones?

Here is what I've come up with, but it contains results that have a null location when there are no ship records:


SELECT
Grids.GridID,
Ships.GridLocation,
Ships.Name
FROM
Grids
FULL OUTER JOIN Ships
ON Ships.GridID = Grids.GridID
WHERE
Grids.PlayerID = 1

UNION-- (**not** UNION ALL)

SELECT
Grids.GridID,
GridLocations.GridLocation,
(SELECT ShipName FROM Ships WHERE GridID = Grids.GridID AND GridLocation = GridLocations.GridLocation)
FROM
GridLocations, Grids
WHERE
Grids.PlayerID = 1

Outer Join:

Aug 10, 2006

Here's the lookup table, tblLookup:

Task
SubTask
Subset
Superset
Description

And here's the more voluminous table, tblRecords, to which I need to join that:

Task
SubTask
Acct_cat
Actual_Amount
Budgeted_Amount

The problem is that the Task data in tblLookup consists only of the first 5 chars of the same kind of data in tblRecords (e.g., if a field on that record in tblRecords says "BILLYGOAT", that field in tblLookup is entered only as "BILLY").

How do I match them up?

Thanks.

Outer Join

Aug 31, 2006

Hello,

I am having problems with an outer join statement.
I have written a procedure that tests a table for missing and corrupt data and
to test my procedure, I take a table with 100% correct entries and corrupt them by hand. Then I test if my repaird data is looking like the correct data did.
To do the test, I copy the correct data into a temp table "copy", join it with the "repaired" table and check if any fields look different. The problem is, that i don't get the missing data. The statement is looking like this:

select o.*,'#',k.* from repaired o right outer join copy k on
(str(o.a) + 'A' + str(o.b) + 'A' + str(o.c) =str(k.a)+ 'A' + str(k.b) + 'A' + str(k.c) )
where
o.D<>k.D or
o.E<>k.E or
o.F<>k.F or
...

I have dont the concatenation because I thougt, that a join with 3 fields could be responsible for not finding the missing data in table "copy".
Before that it looked like:

... on (o.a=k.a and o.b=o.b and o.c = k.c) where ...

In table "copy" is a record missing that is in table "repaired".
Why is my statement not printingout that missing record?
Shouldn't be an outer join exactly what I have to use for finding missing data?

I anybody can help me, I would be very happy.

Outer Join Help

Apr 21, 2004

Ok....I have 3 tables.

Entity
--------
name
entity_key

Address
----------
street
zip
mailing_flag
entity_key

Phone
--------
phone_number
phone_type_key
entity_key


I want to see all of the Entity records with their corresponding Address and Phone records. (select e.name, a.street, a.zip, p.phone_number)But only show the Address record for that Entity if the mailing_flag is 'Y' and I only want to see the Top 1 Phone record where the phone_type_key = 'Home'. If the above criteria isn't met I just want to see nulls for the Address and Phone records.

My problem is getting ALL the Entity records to return. It only wants to give me the Entity records that have Address or Phone associated with them. That and somehow showing the Top 1 phone record for the Entity are my issues.

Any help would be much appreciated......Thanks!

How And Where Do I Add My Outer Join?

Apr 11, 2008

Hello,

I have the following script which is *sort of working* !!

The problem I have is that I need to add an outer join to one of the tables and I don't know where to add it or what the syntax is.

Basically, anyone who has an 'STRA' role in the contacts_roles table does not usually have an email address (shown as communications.notes). However, because I don't have any outer joins in place, the script is ignoring everyone who has an 'STRA' role and only pulling back those with an 'STRE' role.

Any help would be much appreciated as to how and where I put my outer join.

Thanks so much.

Jon



SELECT contacts.label_name, contact_positions.position, contact_roles.role, contact_roles.organisation_number, communications.notes, organisations.status, organisations.name, addresses.address, addresses.town, addresses.county, addresses.postcode
FROM bmf.dbo.addresses addresses, bmf.dbo.communications communications, bmf.dbo.contact_positions contact_positions, bmf.dbo.contact_roles contact_roles, bmf.dbo.contacts contacts, bmf.dbo.organisations organisations

Help With Outer Join

Jun 30, 2006

Hi i am having problem getting a resultset in a specific format which i wanted

i am suppose to get this:

team_id|Student|student_not_yet_submitted
Team 1|A,B,C|A
Team 2|D,E,F|NULL

Where (team_id, student) and student_not_yet_submitted are from different tables. Issue of concatenating aside (i am able to do this with java loop), I derived them like this:

1st select=select team_id, student_name from team, student where (....) to get the 1st 2 columns.

To get the 3rd column,
my second select is the same as 1st select but it has an additional condition based on results from 1st select stmt (using the team_id passed in)

2nd select=select team_id, student_name from team where (..... and student_name not in (a 3rd query stmt with result based on team_id from 1st select statement))

i am trying to use left outer join on student_name to join the 2 stmt together, but i am stuck because the 2nd select statement (or rather the 3rd inner query) requires input from the 1st. is there a more efficient way of doing this?

Inner/Outer Join Help

Mar 6, 2008

Below is my query. I am a relative novice to SQL. I'd like to rewrite this with joins. All should be inner joins except for the last one Aritem to shmast. That should be a left outer join because not all of our invoices (in the Aritem tables) have actually been shipped.

How would I do this? I have already read through 2 SQL books, but the examples they give are much simpler than what I need to do. Here's the Query:

SELECT DISTINCT Ardist.fcacctnum, Ardist.fcrefname, Ardist.fccashid,
Ardist.fcstatus, Armast.fcinvoice, Armast.fbcompany, Armast.fcustno,
Ardist.fddate, Ardist.fnamount * -1 as fnAmount,
glmast.fcdescr,
shmast.fcstate,
slcdpm.fcompany as CompanyName
FROM ardist, glmast, armast, slcdpm, shmast, aritem
WHERE Glmast.fcacctnum = Ardist.fcacctnum
AND Armast.fcinvoice = SUBSTRING(Ardist.fccashid,8,20)
AND Ardist.fnamount <> 0
AND ((Ardist.fcrefname = 'INV' OR Ardist.fcrefname = 'CRM' OR Ardist.fcrefname = 'VOID')
AND Glmast.fccode = 'R')
AND armast.fcustno = slcdpm.fcustno
AND armast.fcinvoice = aritem.fcinvoice
AND left(aritem.fshipkey,6) = shmast.fshipno

RIGHT OUTER JOIN?

Jul 20, 2005

In my (admittedly brief) sojurn as an SQL programmer I've often admired"outer joins" in textbooks but never really understood their use. I'vefinally come across a problem that I think is served by an outer join.-- This table stores the answer to each test questionCREATE TABLE TestResults (studentIdvarchar (15)NOT NULL,testIdintNOT NULL REFERENCES Tests(testId),qIdintNOT NULL REFERENCES TestQuestions(qId),responseintNOT NULL REFERENCES TestDistractors(dId),CONSTRAINT PK_TestResultsPRIMARY KEY NONCLUSTERED (testId, studentId, qId),)-- This table defines which questions are on which testsCREATE TABLE TestQuestions_Tests (testIdintNOT NULL REFERENCESTests(testId),qIdintNOT NULL REFERENCESTestQuestions(qId),)(Table Tests contains housekeeping information about a particular test,TestQuestions defines individual questions, TestDistractors lists thepossible responses.)In schematic form, the simplest form of my problem is to find all thequestions that haven't been answered. That would be:SELECT tqt.qIdFROM TestResults AS trRIGHT OUTER JOIN TestQuestions_Tests AS tqtON tr.testId = tqt.testId AND tr.qId = tqt.qIdWHERE tr.qId is NULLSo far I think this is pretty straightforward and an efficient solution.Agreed?But my real problem is a little bit more complex. What I really want toknow is "for a given student, on a given test, which questions haven'tbeen answered?"So now I have:SELECT tqt.qIdFROM TestResults AS trRIGHT OUTER JOIN TestQuestions_Tests AS tqtON tr.testId = tqt.testId AND tr.qId = tqt.qIdWHERE tqt.testId = '1' AND tr.studentId = '7' AND tr.qId IS NULLIs this the canonical form of the solution to my problem? It seems tome like it is generating a whole slew of rows and then filtering them.Is there a more elegant or efficient way to do it?-- Rick

Create table AreaRoadCode {
AreaCode Int(3),
RoadCode Int(3),
ZipCode Varchar(20)
}
Insert into table AreaRoadCode values (34, 12, '2800 L');
Insert into table AreaRoadCode values (34, 13, '2900 K');
Insert into table AreaRoadCode values (36, 18, '0900 O');


I would like to make an SQL select statement, where I join the two tables, producing the following result:

AreaCode RoadCode ZipCode
==============================
34 12 2800 L
34 13 2900 K
35 21
36 18 0900 O
37 21


Kan anybody tell me, how I do that?

Help With Outer Join

May 7, 2007

I have a table Financial_Values that has the following columns:
Year(pk),
Month (pk),
Account_No (pk),
Amount



The combination year, month & account no varies for each year & month.

I need to create sp or function that creates a result set that has the following columns:

Account_No (pk),
Current Amount,
Prior_Year_Amount
Current YTD_Amount,
Prior_Year_YTD



Because the rows in the Financial_Values (number and values of the Account No) can be

different for the current and prior years, I believe I have to do the following steps



1. Create table #Current_Amount
Year(pk),
Month (pk),
Account_No (pk),
Current_Amount



Insert #Current_Amount
Select Year, Month, Account_No, Amount as Current_Amount
From Financial_Values
Where Financial_Value.Year = @Current_Year

And Financial_Value.Month = @Current_Month



2. Create table #Current_YTD_Amount
Year(pk),
Month (pk),
Account_No (pk),
Current_YTD_Amount



Insert #Current_Amount
Select Year, Month, Account_No, Amount as Current_Amount
From Financial_Values
Where Financial_Value.Year = @Current_Year

And (Financial_Value.Month >= 1 and <= @Current_Month)



3. Create table #Current_Values
Year(pk),
Month (pk),
Account_No (pk),
Current_Amount,
Current_YTD_Amount

Insert #Current_Values
Select #Current_Amount.Year,
#Current_Amount.Month,
#Current_Amount.Account_No,
#Current_Amount.Current_Amount,
#Current_YTD_Amount.Current_YTD_Amount
From #Current_Amount INNER JOIN #Current_YTD_Amount
On #Current_Amount.Year = #Current_YTD_Amount.Year
And #Current_Amount.Month = #Current_YTD_Amount.Month
And #Current_Amount.Account_No = #Current_YTD_Amount.Account_No



4. Create table #Prior_Year_Amount
Year(pk),
Month (pk),
Account_No (pk),
Prior_Year_Amount

Insert #Prior_Year_Amount
Select Year, Month, Account_No, Amount as Prior_Year_Amount
From Financial_Values
Where Financial_Value.Year = @Current_Year

And Financial_Value.Month = @Current_Month



5. Create table #Prior_Year_YTD_Amount
Year(pk),
Month (pk),
Account_No (pk),
Prior_Year_YTD_Amount

Insert #Prior_Year_YTD_Amount
Select Year, Month, Account_No, Amount as Prior_Year_YTD_Amount
From Financial_Values
Where Financial_Value.Year = @Current_Year

And (Financial_Value.Month >= 1 and <= @Current_Month)



6. Create table #Prior_Year_Values
Year(pk),
Month (pk),
Account_No (pk),
Prior_Year_Amount,
Prior_Year_YTD_Amount

Insert #Prior_Year_Values
Select #Prior_Year_Amount.Year,
#Prior_Year_Amount.Month,
#Prior_Year_Amount.Account_No,
#Prior_Year.Current_Amount,
#Prior_Year_YTD_Amount.Current_YTD_Amount
From #Prior_Year_Amount INNER JOIN #Prior_Year_YTD_Amount
On #Prior_Year_Amount.Year = #Prior_Year_YTD_Amount.Year
And #Prior_Year_Amount.Month = #Prior_Year_YTD_Amount.Month
And #Prior_Year_Amount.Account_No = #Prior_Year_YTD_Amount.Account_No



7. Create table #Current_and_Prior_Year_Values

Account_No (pk),
Current_Amount,
Current_YTD_Amount,
Prior_Year_Amount,
Prior_Year_YTD_Amount



Select @Current_Values_Count = Count(Account_No)

From dbo.tblPFW_Current_Values


Select @Prior_Year_Values_Count = Count(Account_No)

From dbo.tblPFW_Prior_Year_Values



If @Current_Values_Count > @Prior_Year_Values_Count

Insert #Current_and_Prior_Year_Values

Select #Current_Values.Account_No,
#Current_Amount.Current_Amount,
#Current_YTD_Amount.Current_YTD_Amount
#Prior_Year_Values.Prior_Year_Amount,
#Prior_Year_YTD_Amount.Prior_Year_YTD_Amount

From #Current_Values RIGHT OUTER JOIN #Prior_Year_Values
On #Current_Values.Year = #Prior_Year_Values.Year
And #Current_Values.Month = #Prior_Year_Values.Month
And #Current_Values.Account_No = #Prior_Year_Values.Account_No

Else

Insert #Current_and_Prior_Year_Values

Select #Prior_Year_Values.Account_No,
#Current_Amount.Current_Amount,
#Current_YTD_Amount.Current_YTD_Amount
#Prior_Year_Values.Prior_Year_Amount,
#Prior_Year_YTD_Amount.Prior_Year_YTD_Amount

From #Prior_Year_Values RIGHT OUTER JOIN #Current_Values
On #Prior_Year_Values.Year = #Current_Values.Year
And #Prior_Year_Values.Month = #Current_Values.Month
And #Prior_Year_Values.Account_No = #Current_Values.Account_No



Steps 1 thru 6 are working fine, however when I get to Step 7, my stored procedure fails with

trying to insert into #Current_and_Prior_Year_Values a null value the primary key Account_No.



If I create all the tables not as temporary tables it still fails the same way, however

if I don't run step seven and then run views like the select statements in Step 7

I get the correct results from the views.



Also if a perform an inner join in step seven vs an right outer join, the step does not fail with

the null insert, however I don't the right number of rows (account no)



I quess my question is why would the right outer joins in step 7, run as part of a sp, return

any null Account No values?



Or could anyone suggest a different way to get the result set I need?

How Do I Fix This RIGHT OUTER Join?

Nov 19, 2007



I am trying to grab All Sales Reps (no matter if they have any valid records, i just want to show all names) and Display all question descriptions (even if the question wasnt answered). So it should look like this:
Travel Holiday Sick Ride With Office Day Vacation Seminar
Sally jones 5 1

Kim Smith 2
Tawny Rodes
Jim Tyler
Steven Jones
Calvin Moore
Tina Hood
Cristine Smart 3 20
Mark foley
Fred Rogers 2

Instead im getting this:

Travel Holiday Ride With Vacation
Sally jones 5 1

Kim Smith 2
Tawny Rodes
Cristine Smart 3 20
Fred Rogers 2

Here's my query:




Code Block
SELECT
Qry_Sales_Group.Name,
Qry_Sales_Group.SR_NAME,
Qry_Sales_Group.Salesperson_Purchaser_code as SR_Code,
CONVERT(datetime, DATEADD(day, q.cycle_day - 1, q.start_date), 6) AS Logged_Time,
y.question_code,
y.description,
q.response

FROM Qry_Sales_Group
LEFT OUTER JOIN(SELECT CONVERT(datetime, DATEADD(day, dbo.question_history.cycle_day - 1, dbo.period.start_date), 6) AS Logged_Time,
Qry_Sales_Group.SR_Name,
Qry_Sales_Group.Name,
questions.question_code,
questions.description,
question_history.response,

ON questions.question_code = question_history.question_code
INNER JOIN period
ON question_history.period_code = period.period_code
RIGHT OUTER JOIN Qry_Sales_Group
ON SUBSTRING(dbo.question_history.entity_code, 1, 5) = dbo.Qry_Sales_Group.SalesPerson_Purchaser_Code COLLATE Latin1_General_CI_AS

WHERE CONVERT(datetime, DATEADD(day, dbo.question_history.cycle_day - 1, dbo.period.start_date), 6) = '11/14/2007' AND
(dbo.questions.question_code IN ('AME01', 'ASE01', 'ACO01', 'ALU01', 'AOS01', 'APH01', 'ATR01', 'ATE01', 'ACR06', 'ACR05', 'ACR02', 'ACR03', 'ACR08',
'ACR07')) ) q
ON SUBSTRING(q.entity_code, 1, 5) = Qry_Sales_Group.SalesPerson_Purchaser_Code COLLATE Latin1_General_CI_AS
RIGHT OUTER JOIN(Select

question_code
from Questions
Where questions.question_code IN ('AME01', 'ASE01', 'ACO01', 'ALU01', 'AOS01', 'APH01', 'ATR01', 'ATE01', 'ACR06', 'ACR05', 'ACR02', 'ACR03', 'ACR08',
'ACR07') )y
ON y.question_code=q.question_code


order by QRY_SALES_GROUP.SR_NAME




Please help. If i do a Right outer join, i get all the questions i want. But if i do a left outer join i get all the sales reps. How do i get both??

OUTER JOIN PROBLEM

Feb 4, 2004

My SQL Statement as follows:

SELECT S.SessionID,S.SessionName,T.number
FROM Sessions S LEFT OUTER JOIN (SELECT SessionID,COUNT(*) AS number
FROM EventLog
WHERE MachineID = @machineID
GROUP BY SessionID) AS T
ON S.SessionID = T.SessionID
ORDER BY S.SessionID

The result sets T.number as NULL if there is no record related to SessionName. How to change NULL to ZERO?
Thanks a lot.

Help With Outer Join Query Please!

Jul 5, 2004

I have a MSDE query that includes a "left outer join..." clause. It runs fine in MSDE Query (a 3rd party GUI tool) and produces 12 rows. column 3 has some NULL values (because of the outer join).

But when I use the same query in an ASP.NET page, and display the result in a datagrid, it only displays 7 rows - the rows with the NULL value in column 3 do not display.

Is there a parameter somewhere in datagrid or dataset that I should be setting?

thank you someone!

OUTER JOIN Issue

Jul 1, 2005

Hi all,

I have two tables (for example, table1, table2) where table1 holds the
same data as table2 but also has other rows that are no contained in
table2.

Now if I performed the following query...

SELECT table1.name
FROM table1
LEFT OUTER JOIN table2 ON (RTRIM(LOWER(table1..table_name)) = RTRIM(LOWER(table2.table_name)))

... I expect to get the rows that are not contained in both tables. But
for some reason I don't get this. I get all the rows from tabel1.

Is my thinking of what the LEFT OUTER JOIN query wrong, or is the query wrong?

To get around my problem, I had to do the following

SELECT table1.name

FROM table1
WHERE table1.table_name not IN (SELECT table_name FROM table2)

I would have preferred to have solved this with the LEFT OUTER JOIN though

Thanks

Tryst
