EJB3 - QL using Left Join
I have customer entity.
To get the customer country i have to get it from the tablecountry thru countryID.
How will i apply my LEFT JOIN for my sessionbean?
this is my simple query for mssqlserver:
"select Country from customer c left join tblCountry tc on c.idcountry = tc.idcountry where idcustomer = 888"
and my EJBQL:
"select o.iDCustomer,o.firstName,o.lastName," +
"tc.Country from Customer o LEFT JOIN o.IDCountry tc WHERE o.iDCustomer LIKE '"+ IDCustomer +"' AND o.IDCountry = tc.IDCountry"
pls. help me edit my EJBQL query.
thanks.

I want to join tables from customer_ads and customers when there is a match (and there always will be).
However on the receivables table there may or may not match and if not I want to return that value as blank, but still need it returned.
This above now returns the same OrderID over and over agian, but they with different cust_check_num when I add the ", receivables.cust_check_num" before the FROM statement as I am trying to retun that value. Does that make sense?
Example:
SELECT DISTINCT(billing.orderID),media.pub_name, billing.space_cost, billing.pub_box, billing.messenger, billing.rs_fax, billing.rs_box, billing.bold, billing.rs_email, billing.logo, billing.prod, billing.pdf, billing.printnpost, billing.shading, billing.fedex, billing.web_charge, billing.pre_pay, billing.mailed, billing.media_cost, billing.weekday_addon, billing.misc, billing.printnpostCost, billing.miscCost, billing.fedexCost, billing.net_space_cost, billing.pubsWebChargeFee, customer_ads.rs_inv_num, customer_ads.start_date, customer_ads.id, customers.company, customer_ads.job_title, customer_ads.estimatedCost, receivables.cust_check_num
FROM (((billing
LEFT JOIN customer_ads ON customer_ads.id = billing.orderID)
LEFT JOIN customers ON customer_ads.client_id = customers.customers_id )
LEFT JOIN receivables ON customer_ads.client_id = receivables.client_id )
LEFT JOIN media ON media.id = customer_ads.media_id
WHERE (start_date >= "2013-01-26 00:00:00") AND (start_date <= "2013-01-28 23:59:59")

I have this query in Oracle and I am trying to write a Linq query for this below sql. There are 2 datatables DATA_TABLE1 and DATA_TABLE2. Both tables have 2 fields ID1 and ID2.
SELECT A.ID1, A.ID2
FROM DATA_TABLE1 A
LEFT JOIN DATA_TABLE2 B
ON A.ID1 = B.ID1 AND A.ID2 = B.ID2
WHERE B.ID1 IS NULL OR B.ID2 IS NULLIn order to see what query the data provider sent to the server you can do the following.
Just after creating the data context place this line in the code.
db.Database.Log = Console.Write;
Then place a breakpoint after the next line of code, shown next.
var
a =
db.product.Where(p
=>
p.Name.Contains(asKeyword)).ToList();
Then run the application and when it hits the breakpoint open the Visual Studio Output window and the SQL sent to the server should be displayed.

Simple left-join doesn't work. error with: Unknown column
Hi guys,
can anyone assist on this simple query:
SELECT D.* , SUM( TD.debit_amount), SUM(TAP.amount)
FROM debit AS D, transaction_debit AS TD
LEFT JOIN TA_PAYMENTS AS TAP ON D.debit_id=TAP.debit_id
WHERE D.debit_id = TD.debit_id
GROUP BY TD.debit_idThe error message I receive is:
#1054 - Unknown column 'D.debit_id' in 'on clause' I'm trying to relate 3 tables (debit, transactions-debit and ta_payment), some payment may not exist so therefore i use left join.
thanks for any pointersSELECT D.* , SUM( TD.debit_amount), SUM(TAP.amount)
FROM debit AS D, transaction_debit AS TD
LEFT JOIN TA_PAYMENTS AS TAP ON
D.debit_id=TAP.debit_id
WHERE D.debit_id = TD.debit_id
GROUP BY TD.debit_id
I'm trying to relate 3 tables (debit,
transactions-debit and ta_payment), some payment may
not exist so therefore i use left join.You are trying to mix "the older join syntax", with the join condition in the where-clause, with "the new join syntax", with the join condition in the "on-clause", which I think is causing trouble.
How about using only "the new syntax":
SELECT D.* , SUM( TD.debit_amount), SUM(TAP.amount)
FROM debit AS D JOIN transaction_debit AS TD on (D.debit_id = TD.debit_id)
LEFT JOIN TA_PAYMENTS AS TAP ON (D.debit_id=TAP.debit_id)
GROUP BY TD.debit_idDoes that help? -
Inconsistent results with ANSI LEFT JOIN on 9iR2
Is this a known issue? Is it solved in 10g?
With the following data setup, I get inconsistent results. It seems to be linked to the combination of using LEFT JOIN with the NULL comparison within the JOIN.

It seems to matter what order I specify the operands stor_id = 3, or 3 = stor_id.
In the older (+) environment, I would understand this, but here? I'm pretty sure most other databases don't care about the order.
thanks for your insight

How can I use the join condition for this query?
Hi, i am using a query which has a sun query in it, wen i am running tat query it is giving 9332 records, I changed the sub query logic and given an inner join, but it is giving only 4476 records. So, I changed it to left join but it is giving more records
than usual now, say 10033 records.
This is the code which is giving records 9332, which is correct
select distinct
b.SRC_PROV_ID
,COALESCE(a.SYSTEM_NAME, a.CTRCT_GRP_NAME, a.PROV_SMG_NAME) AS SYSTEM_NAME
INTO TINtoSystem
from
RARE.dbo.EDW_MASTER a
Inner Join RARE.dbo.EDW_PROD_ID_XREF b
on a.SMG_ID = b.SMG_ID
where SRC_PLATFORM_CD = 'TX'
and a.SMG_ID in
select distinct
SMG_ID
from RARE.dbo.EDW_PROD_ID_XREF
where SRC_PLATFORM_CD = 'TX'
and SRC_PROV_ID in (select q.PROV_TAX_ID from PACT.dbo.SQS_EDW_Source q)
I have changed this code by giving inner join as, but its not giving the exact records of 9332,
select distinct
b.SRC_PROV_ID
,COALESCE(a.SYSTEM_NAME, a.CTRCT_GRP_NAME, a.PROV_SMG_NAME) AS SYSTEM_NAME
INTO TINtoSystem
from
RARE.dbo.EDW_MASTER a
Inner Join RARE.dbo.EDW_PROD_ID_XREF b
on a.SMG_ID = b.SMG_ID
Inner Join Pact.dbo.SQS_EDW_Source q
on b.SRC_PROV_ID = q.PROV_TAX_ID
where b.SRC_PLATFORM_CD = 'TX'
Can anyone tell, where it is missing, I used left join also but its giving more records then, need helpHi, If you insist inner joins then please try
SELECT DISTINCT
b.SRC_PROV_ID
,COALESCE(a.SYSTEM_NAME, a.CTRCT_GRP_NAME, a.PROV_SMG_NAME) AS SYSTEM_NAME

Hi SAP,
I have an access database with table called "Employee_ID". I am linking this table to a table called "Sales" in our main database and trying to report on January 2009.
There is one employee that is not appearing in my report. I know this employee has had no sales in Jan 2009. So, I tried linking the table using Left Outer Join and still this employee is not appearing in my report.
As a test, when I bring in Employee_ID table alone, the missing employee appears but when I try linking it INNER or LEFT OUTER join to table Sales, this employee does not appear.
Any help how I can bring the employee in from table Employee_ID?
Many thanks in advance,
Zack H.Carl & Raghavendra,
Your suggestion led me to the finding my solution. Your suggestion brought back the missing employee but I needed all employees that had sales in January 2009 AND those that didn't. So I had to tweak your select expert formula as follows:
isnull({Sales.amt}) or
{Sales.period}="0109"
This brought back everything as needed! There was one negative about using this method. The performance was poor. It took a really long time to run.
To avoid having to wait for this to run and increase the performance, I had to go into the database and add a $0.00 sales amt for employee 2040 (or an empty sales amount record) in the month of January 2009. This brought back everyone also and it obviously increased the performance exponentially. Curious, why does it take forever to run using the above formula in select expert?
Thank you both Raghavendra and Carl for your relentless efforts to find a solution. You did it!

How to do inner join ,outer join, left join ,right join by using infoset
how to do inner join ,outer join, left join ,right join by using infoset
Hi
If you want to make join ,outer join, left join ,right join then its possible if you are using ODS or direct infoobject (In BW3.5) and if you are using BI7.0 then you also make join ,outer join, left join ,right join with Cube also.
For making join ,outer join, left join ,right join in infosets you just select your info provider then right click on your infoarea from context menu select info set after doing this one pop-up opens here u define your infoset technical name and give either ODS object name of infoobject name.
After doing this next screen opens in right hand side your selectes ODS or infoobject shows in graphical format .
and left hand side it shows one menu bar here you can select another ODS or infoobject for making join ,outer join, left join ,right join .just click on ODS button in menu bar and select ODS drag your selected ODS from Left to right after doing this your selected ODS shown in right hand side window in graphical format you just now after doing this you are able to make join ,outer join, left join ,right join for this first you select field from one ods and drag a line from 1 ods to second ods after doing this one arrow is created from one ods to another ods just right click on arrow and make join ,outer join, left join ,right join in to your ODS.
I think its clear how we can we make join ,outer join, left join ,right join in infoset.If you have any further query then welcome.

How to use left outer join on more than one table (source)
Hi all,
In our project we are converting the Unix shell & SQL scripts into OWB mappings. We are facing problem converting left outer join in OWB. here is one of the example. i have just pasted the FROM and where condition.
FROM ym_scr t1, branch_finmonth t3
LEFT OUTER JOIN item_image t2
ON (t1.branch_no = t2.branch_no
AND t1.item_no = t2.item_no
AND t3.to_date between t2.tran_dt and t2.to_dt
AND t2.to_dt >= '$start_images' ) <<<========= '$start_images' THIS COMES FROM THE UNIX VARAIBLE ,
We converts the same when we are putting it in OWB join Operator
INGRP1.branch_no = INGRP2.branch_no(+)
AND INGRP1.item_no = INGRP2.item_no(+)
AND INGRP3.to_date between t2.tran_dt and t2.to_dt
AND INGRP2.to_dt >= INGRP2.start_images
But as you see in the OWB opreator we can put left join with INGRP1 with INGRP2.
We can not make same join with INGRP3 & INGRP4 , becoz it failed saying "you cannot left outer join on more than one table/source".
so overall this OWB code makes incomplete left outer join as per the above ANSI SQL join in Oracle.
Bcoz of the problem we are getting less number of rows...........
SO please please help me on this
Regards
AshokHi.
I know this topic is here for a while now, but I had the same problem today, searched for help and didn´t find anything.
Later I figured out how to do this.
You just have to put the (+) one time, and the OWB converts in an LEFT OUTER JOIN statement.
For this case, all you have to do is:
( INGRP1.branch_no = INGRP2.branch_no(+) AND INGRP1.item_no = INGRP2.item_no AND INGRP2.to_dt >= INGRP2.start_images )

Using Left Outer Join along with reference
I have three tables.
Table 1 : BOOK_DETAILS
Fields: BOOK_ID, BOOK_NAME
Table 2: BOOK_ISSUE_RECORD
Fields: BOOK_ID, USER_NAME
Table 3: BOOK_AUTHOR
Fields: BOOK_ID, AUTHOR_NAME
I have to link Table 1 and Table 2 with Left outer Join because even if the book is not issues to anyone, its name should come.
Again I have to display the Book Author name for each Book.
I am able to create a query with the Left outer join between Table 1 and Table 2. However I am not able to give a reference to the Table 3.
Can any one please help me with this.

Left Join query: revisited... I have to explain at user meeting tomm. pls..
Hi Everyone,
Can someone pls shed some light on the situation below
I am understanding alot of what Michael and Rod wrote.... with my prev. post of LEFT JOIN and testing for
not null and doing a double Boolean OR etc.
- but- AM NOT understanding why the IS NOT NULL works, without the double boolean OR
Pls help... have to explain what left join means to user tomm. I'm going to demo the query below and
not the one with the double boolean OR bec. maybe too much info to present at one sitting. tx, sandra
=====================
the query below is left joining the STUDENT table to
HOLD table.
The HOLD table - contains rows for students who have holds on their record.
a student can have more than one hold (health, HIPAA, basic life saving course)
BUT, for this query: I'm only interested that a hold exists, so I'm choosing MAX on hold desc.
Selecting a MAX, helps me, bec. it reduces my join to a 1 to 1 relationship, instead of
1 to many relationship.
Before I posted this thread at all, the LEFT JOIN below testing for IS NOT NULL worked w/o
me having to code IS NOT NULL twice....
Is that because, what's happening "behind the scenes" is that a temporary table containing all max rows is being
created, for which Discoverer has no predefined join instructions, so it's letting me do a LEFT JOIN and have
the IS NOT NULL condition.
I would so appreciate clarification. I have a meeting on Tues, for which I have to explain LEFT JOINS to the user
and how they should create a query. I need to come up with rules.
If I feel "clear", I asked my boss to buy Camtasia videocast software to create a training clip for user to follow.
Also, if any Banner user would like me to email the DIS query to run on their machine, I would be glad to do so.
thx sooo much, Sandra

OK, I will try to explain this. When you outer join table B to table A then the rows in table A which do not match any rows in table B will returned with NULL in the columns from the table B.
Oracle uses the syntax ( +) for outer joins. Now if you add another condition using the ( +) syntax (as shown below) the condition will be processed before the table is joined. Therefore if table A does not match any rows in table B which have col2=1 then the row from table A will be returned with NULLs for the table B columns.
SELECT A.col1, B.col1
FROM A, B
WHERE A.col1 = B.col1( +)
AND B.col2( +)=1
Now, if the condition B.col2=1 was used instead then the condition would be processed after the join and therefore the rows from table A that were joined to table B but did not meet the condition would not be returned by the query.
This applies to a WHERE clause and to the HAVING clause, but with one exception. If you use the ( +) within a group function in a HAVING clause then the ( +) will have no affect because the condition must be processed after group by and group by can only be processed after the join. Therefore MAX(B.col2( +)) = 1 is processed after the join even through it uses the ( +) syntax.
You cannot use an OR or an IN with the ( +) syntax because the meaning of the OR in this situation is ambiguous, is the OR done before or after the join. A query with an OR or IN in an outer will fail with an Oracle ORA-01719 error. Discoverer recognises this situation and removes the ( +) so that the error does not occur. However, without the ( +) the conditions are processed after the join.
Using the ( +) with IS NULL, e.g. col2( +) IS NOT NULL works in the same way. You just have to remember that the col2( +) could be NULL as a result of the outer join and therefore if the condition is processed after the query then the IS NOT NULL will remove the outer joined rows.
Hope that is clear.

Left join (+) instead of "not in"
Hi all!
I've got statement with "where dig not in (840, 978)" string.
How do I write statement without "not in" ?
I thought about left join and "is not null", but don't know exactly how to use it.
Any ideas?
Thanks ahead.Here is my solution:
select d.* from
(select 111 as accountno, 840 as currencyid from dual
union all
select 222 as accountno, 978 as currencyid from dual
union all
select 333 as accountno, 826 as currencyid from dual ) d ,
(select 840 as dig from dual
union all
select 978 as dig from dual ) j
where d.currencyid = j.dig(+)
and j.dig is null
Thanks to all. -
Hi guys,
I am not sure why the left join is not working.. when I try to use the and condition out of the left join condition. The database is relational but the requirement is for reporting. I have 2 user inputs and I should get the query results as explained below..
Let me explain with the sample data.
Table 1: PRTYPE (P)
TYPEID CLASSID
T001 CLS001
T001 CLS002
T001 CLS003
T002 CLS002
T003 CLS001
Table 2: EMPLOYEE (E)
EMPID NAME
E001 Joe
E002 Mark
E003 Lucy
Table 3: DETAILS (D)
EMPID CLASSID STATUS
E001 CLS001 NEW
E001 CLS002 DONE
E002 CLS001 NEW
E002 CLS004 NEW
Report1:
Input: PRTYPE.TYPEID = T001, EMPID = E001
Output:
E.NAME E.EMPID P.TYPEID A.CLASSID D.STATUS
JOE EMP001 T001 CLS001 NEW
JOE EMP001 T001 CLS002 DONE
JOE EMP001 T001 CLS003 BLANK
Report2:
PRTYPE.TYPEID = T003, EMPID = E003
E.NAME E.EMPID P.TYPEID A.CLASSID D.STATUS
LUCY E003 T003 CLS001 BLANK
LUCY E003 T003 CLS004 BLANK
When I use and condition in left join itself, it works but when I take it to the end of the sql using where p.typeid= T001 and E.EMPID = E001 I am not getting the left join results... It looks like Oracle doesn't like the condition at the end. I hope I am clear on explaining. Please share your experience on how to get it working..

Why don't you post your query? You know, it will be easier for someone to tell you what you're doing wrong if they know what you're doing.
Are you saying that you get the correct results when you have a cerain condition in an outer join, but that you get the wrong results if you put the exact same condition in the WHERE-clause?
If so, keep the condition where it does what you want.
You can usually move INNER join conditions around like that, but never OUTER join conditions.
As Alex said, if you want help, post executable statement to create and populate your tables with a little sample data, as well as the output you want from that sample data, and your best attempt at a query. -
Using nested Joins in abap prog
Hi All,
please help me out in using nested joins in abap progrmaming. I dont know about joins in abap.specially in case of outer join.
I have 5 internal tables.. mara ,marc, mvke,mbew,ampl. am using a select query with certain fields from all these tables.
I need to disply all the materials of a mara for a particular date irrespective of the values in fields of other tables.
Even if that materail is not present in other table for certain condtion ,that material should get displyed with all other fields showing null value..Hi RK,
the code am using is of the same way...but my problem was with the joins..in the select query am using nested join combining inner and outer join.. but i could not able to display all the materials of mara of a particular date..
The code looks like this..
SELECT <some fields.......>
INTO TABLE i_materials
FROM ( marc AS b
INNER JOIN mara AS a ON amatnr = bmatnr
INNER JOIN mvke AS c ON cmatnr = amatnr
INNER JOIN ampl AS g ON gbmatn = amatnr
LEFT OUTER JOIN mbew AS d ON dmatnr = bmatnr
AND dbwkey = bwerks )
WHERE a~matnr IN s_matnr AND .................
Else
SELECT <some fields.......>
INTO TABLE i_materials
FROM ( marc AS b
INNER JOIN mara AS a ON amatnr = bmatnr
INNER JOIN mvke AS c ON cmatnr = amatnr
INNER JOIN ampl AS g ON gbmatn = amatnr
LEFT OUTER JOIN mbew AS d ON dmatnr = bmatnr
AND dbwkey = bwerks )
FOR ALL ENTRIES IN i_mara
WHERE a~matnr = i_mara-matnr AND ............
