I came across this statement from ASP.NET forum : "..There is a limit to the level for OUTER JOIN ANSI SQL limit is four after that you may get strange results. ..." . I did a little research but without getting clear answer from the SQL92 standard itself. I am wondering whether I can get help about this in SQL Server 2005 implementation here.
I put this question in another way, How many tables can we use in OUTER JOIN(or INNER JOIN) in SQL Server 2005?
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.
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) go insert parent values (1) insert parent values (2) 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
What is the best way to use a left join in a SQL statement with multiple tables (more than 2)? I have a query that uses 7 tables, where most of the joins are inner joins, except for one, which needs to be a left join. The current SQL statement looks something like this:
FROM [table1],[table2],[table3],[table4],[table5],[table6],[table7] WHERE [table4].[field2]=[table1.field2]{this is an inner join} [table4].[field2]=[table2.field2]{this is an inner join} [table4].[field2]=[table3.field2]{this is an inner join} [table4].[field2]=[table5.field2]{this is an inner join} [table5].[field3]=[table6.field2]{this is an inner join} [table5].[field4]=[table7.field2]{this is needs to be a left join}
As it stands now, the last line in the WHERE clause is an INNER JOIN and limits the number of rows in my result. I need to select rows from [table7].[field2] whether or not a matching record exists in [table5].[field4]. The other INNER JOINS in the SQL statement must have matching records. Please advise.
This might not be possible, but on the chance that it can - is there away to do the following:Given a arbitray one dimesional value list:('AALGX','12345','XXXXX','AAINX','AMMXX')Is there a way that I could do a select statement, or similiar, in thevalue list, to get the following resultfield_name-----------AALGX12345XXXXXAAINXAMMXXBecause, what I want to be able to do in the long run is essentiallyperform an outer join on the value list.Something along the lines ofselect value_list.field_name, dbtable.otherfield FROM value_list leftouter join dbtable on value_list.field_name = dbtable.field_nameSo I want all the values in the field list to show up, and anymatching data in the database table that exists, otherwise null.Maybe there is another approach to this???Thanks!KT
I want to use multiple datasets in a table and wants to do the full outer join on the two datasets in the same table. For example, my two datasets are:
I want to display a ssrs table like: Both the datasets are coming from different sources. So I cannot integrate them at sql query level.
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)

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

hello, i am running mysql server 5 and i have sql syntax like this: select sales.customerid as cid, name, count(saleid) from sales inner join customers on customers.customerid=sales.customerid group by sales.customerid order by sales.customerid; it works fine and speedy. but when i change inner join to right join, in order to get all customers even there is no sale, my server locks up. note: there is about 10000 customers and 15000 sales. what can be the problem? thanks,
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
There is a table called "tblvZipCodes" that contain a zipcode of all cities, area code that are located in that zip code.
The problem I have with the inner join is that there are more than 1 cities in one zipcode code. Is there a way to just return only the 1st row and not return the rest of the rows from the tblvZipCodes in the INNER JOIN query?
Thanks..

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".
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
The following query doesn't work, it display 1 in leads column instead of 0:
select t.Tdate, count(l.id) as Leads, sum(t.shown) as Views from tracking t left outer join Leads l on r.clientid = t.clientid where l.clientid = 101 and l.Ldate >= 'April 2,2004' and t.Tdate >= 'April 2,2004' group by t.Tdate
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").
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 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.
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.

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?
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
what is difference between inner join and outer join also right and left join can you explain with simple example(because i m fresher) and the query which are there in previous forum will work for the mainframe environment?
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
Wonder if any could help be putting together a SQl select statement. I have 2 tables of road-data, one having default data for the area, and one with actual data. They look like this:
Create table AreaDefaults { AreaCode Int(3), RoadCode Int(3) } Insert into table AreaDefaults values (34, 21); Insert into table AreaDefaults values (35, 21); Insert into table AreaDefaults values (36, 21); Insert into table AreaDefaults values (37, 21);
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)
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
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?
