SQL Select using LEFT OUTER JOIN returning field values when I expect NULL

I am having problems with this select statement:
SELECT distinct pl.id, th.trip, pc.country, pph.location
FROM people_list pl, people_travelhistory th, people_country pc
LEFT OUTER JOIN people_info pph on pph.id=pl.id and pph.country=pc.country
where people_list.active='Y' and people_list.id=th.id and th.trip = pc.trip;
The criteria is that the pph table may not have no record for that id and country.
The problem is that the pph.location field is returned with data even when no matching record for that id or country exists.
If the record doesn't exist in the pph table, I want pph.location = NULL
What am I doing wrong?
Thanks in Advance!

Hi, You can try this :
SELECT distinct pl.id, th.trip, pc.country, pph.location
FROM people_list pl, people_travelhistory th, people_country pc
left outer join people_info pph on pph.id = pl.id
left outer join people_country pc on pc.country = pph.country
left outer join people_travelhistory th on th.id = pl.id
where pl.active='Y' and th.trip = pc.trip;
Knowing that you requesting people active that have travelled to their own country.
Regards

Using Left Outer Join

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!

Need to adjust SQL query for left outer join in Crystal Reports 2008.

I need to change this SQL 2005 query.....
SELECT     omnicell_anl.DeviceIDsLastMetricTable.member_id, omnicell_anl.DeviceIDsLastMetricTable.[Device Name],
                      omnicell_anl.DeviceIDsLastMetricTable.Account, omnicell_anl.labeledLastMetrics.PROPERTY_NAME,
                      omnicell_anl.labeledLastMetrics.latest_monitor_value
FROM         omnicell_anl.DeviceIDsLastMetricTable LEFT OUTER JOIN
                      omnicell_anl.labeledLastMetrics ON omnicell_anl.DeviceIDsLastMetricTable.member_id = omnicell_anl.labeledLastMetrics.member_id
WHERE
    omnicell_anl.labeledLastMetrics.PROPERTY_NAME = ?MyProperty
To this query in Crystal Reports Report Writer:
SELECT     omnicell_anl.DeviceIDsLastMetricTable.member_id, omnicell_anl.DeviceIDsLastMetricTable.[Device Name],
                      omnicell_anl.DeviceIDsLastMetricTable.Account, omnicell_anl.labeledLastMetrics.PROPERTY_NAME,
                      omnicell_anl.labeledLastMetrics.latest_monitor_value
FROM         omnicell_anl.DeviceIDsLastMetricTable LEFT OUTER JOIN
                      omnicell_anl.labeledLastMetrics ON omnicell_anl.DeviceIDsLastMetricTable.member_id = omnicell_anl.labeledLastMetrics.member_id AND
                      omnicell_anl.labeledLastMetrics.PROPERTY_NAME = ?MyProperty
I can't seem to get the left outer join function of Crystal Reports to emulate the same SQL query in SQL 2005. Any ideas on how I can create this same query in Crystal 2008?
Thanks,
Dominic

If you want the list of values for command level parameter then you need to add another command like
select PropertyField from table
and delete the links between this command and the existing command.
Now go to field explorer and edit the command level parameter and make it as dynamic and add the property field from newly added command.
Hope this helps!

Multiple tables using left outer join?

Hi, guys:
I have 4 tables: A, B, C; if I want to do the following:
A left outer join B, its result left outer join C.
How can I do that? BTW, I am using DB2.
The following is a sample inner join:
select a.id, b.first, c.last
from A as a, B as b, C as c
thanks

select ..
from A a
left outer join B b ON ....
left outer join C c ON ...
WHERE ...

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
Ashok

Hi.
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.
Regards
Hawker

How to use "left outer join" in SQVI

Dear ALL ,
I want to match MARA materials with BOM material table (MAST,STPO)material or Routing material table (MAPL,PLPO) and I want the list of NONMATCHING material codes from SQVI.
How to get these items which do not match in 2 tables........?
I have to work with SQVI + EXCEL ( VLOOKUP ) in excel sheet.
Thanks...

Kishore,
After selecting the table join option, In layout mode enter the table names in Joined tables tab. Select the 2 tables using check boxex and select the join type like left inner and click on define condition. This would create a left inner join. Similarly carry out for the next 2 tables.
Hope it is useful. If so reward your points.

Web services test using WS Navigator doesnot return field values

Hi experts,
We are running ECC 6 (NW 7 Ehp1) ABAP stack and NW CE 7.1 with Java stack (J2EE Engine 7.11). We are trying to test web services using WS Navigator. We can logon to WS Navigator and perform the test. The test shows a success return code, however, it doesn't bring back field values. We can see the values when we perform this test within ABAP stack. A sample of WS Navigator XML log for the service test is as below:

Not able to clear out a formula field value when variables are equal to 0

I am trying to calculate the difference between a formula field from a main report and a formula field from a subreport. When i run the report i get a correct difference calculation only when both formula fields have a value different than 0. When both values are 0 then the difference calculation shows the last item quantity from the formula field in the subreport that had different values than 0. It looks like the difference calculation is not being clear out before jumping to the next value calculation.

try to clear the variable values once done with calculation like
whileprintingrecords;
shared numbervar i:=0;

Raghavendra

Not using Index when SDO_RELATE in Spatial Query is used in LEFT OUTER JOIN

I want to know for every City (Point geometry) in which Municipality (Polygon geometry) it is.
Some cities will not be covered by any municipality (as there is no data for it), so its municipality name should be blank in the result
We have 4942 cities (point geometries)
and 500 municipalities (polygon geometry)
SELECT T1.NAME as City, T2.NAME as Municipality
FROM CITY T1
LEFT OUTER JOIN MUNICIPALITY T2 ON SDO_RELATE(T1.GEOM, T2.GEOM, 'MASK=ANYINTERACT') = 'TRUE'The explain plan for this query is:
SELECT STATEMENT
FILTER
    Filter Predicates
      MDSYS.SDO_RTREE_RELATE(T1.GEOM, T2.GEOM, 'mask=ANYINTERACT querytype=window ') = 'TRUE'
    MERGE JOIN
      TABLE ACCESS              CITY               FULL                            11
      BUFFER                                       SORT                        100605
          TABLE ACCESS          MUNICIPALITY       FULL                            20So the cost is in the BUFFER (whatever that is), it takes +2000 seconds to run this, it is not using the spatial index.
And we are not getting all rows, but only the ones interacting with a municipality, e.g. 2436 rows.
But I want all rows, including the ones not interacting with any Municipality.
When we want only those cities that actually are in a municipality, I use a different query and it will use the index.
SELECT T1.NAME as City, T2.NAME as Municipality
FROM CITY T1, MUNICIPALITY T2
WHERE SDO_RELATE(T1.GEOM, T2.GEOM, 'MASK=ANYINTERACT') = 'TRUE'I get (only) 2436 rows (as expected) in 5 seconds (it is fast) and the explain plan shows it is using the spatial index.
But in this case, I am not getting any cities not inside any municipality (of course)
SELECT STATEMENT
   NESTED LOOPS
      TABLE ACCESS                   MUNICIPALITY       FULL                22
      TABLE ACCESS                   CITY               BY INDEX ROWID      22
         DOMAIN INDEX                CITY_SDX                                0
            Access Predicates
               MDSYS.SDO_RTREE_RELATE(T1.GEOM, T2.GEOM, 'mask=ANYINTERACT querytype=window ') = 'TRUE'I always thought a LEFT OUTER JOIN would return all rows from the Table, whatever happens in the next,
but it seems the query has been rewritten so that it is now using a Filter Predicate in the end, which filters those geometries having no interaction.
As an example I also do thing alphanumerically, I do get 4942 rows, including the ones which have no Municipality name.
In this case the names must match, so its only for testing if the LEFT OUTER JOIN returns stuff correctly, which it does in this case.
SELECT T1.NAME as City, T2.NAME as Municipality
FROM CITY T1
LEFT OUTER JOIN MUNICIPALITY T2 ON T1.NAME = T2.NAMEIs this an Oracle Spatial bug, e.g. not return 4942 rows, but only 2436 rows on the first query?
Note all tests performed on Oracle 11g R2 (11.2.0.1.0)

Patrick,
Even so, your geoms in the relate were the wrong way around.
Also, I don't recall you saying (or showing) that you wanted the municipality geometry returned. Still,
no matter, easy to do.
Here are some additional suggestions. I don't have your data so I have had to use some of my own.

Left outer join using multiple table

Hi,
I am trying to use left outer join with multiple tables , the join condition will be based on PERNR and BEGDA & ENDA for each infotype in selection screen.
select pa00~pernr pa00~begda pa00~endda pa00~massn pa00~massg pa00~stat2 pa00~aedtm pa00~uname

    pa02~begda pa02~endda pa02~nachn pa02~vorna pa02~midnm pa02~aedtm pa02~uname
    pa016~begda pa016~endda pa016~cttyp pa016~aedtm pa016~uname
    into CORRESPONDING FIELDS OF TABLE i_pall

    left OUTER JOIN pa0002 as pa02 on pa00~pernr eq pa02~pernr )
    left OUTER JOIN pa0016 as pa016 on pa00~pernr eq pa016~pernr )
    where pa00~pernr in S_pernr
    AND pa00~begda in s_bg0000
    and pa00~endda in s_nd0000.
but this fails to fetch the value of begda enda from each pa0000,pa0001,pa0002,pa0016.
Please help!

Nested Left Outer Join : Data Set

Hi All
I am bit confused about data set used by Nested Left outer join.
Can anyone help me.
Here is sample data:
Tables (Name, 3 Column each, total rows and matched rows if any):
     Table 1
     A     B     C
     Total 20 Rows
     Table 2
     A     D     E
     Total 50 Rows and 10 Matching on      2.A = 1.A
     Table 3
     D     M     N
     Total 15 Rows and 15 Matching on 3.D = 2.D
     Table 4
     M     X     Y
     Total 20 Rows and 10 Matching on 4.M = 3.M
Sql
select *
From Table 1
Left Outer Join on Table 2 on
               2.A = 1.A
-- Data set 1 will contain 20 Rows (10 matching and 10 non matching)
Left Outer Join on Table 3 on
               3.D = 2.D
-- What will be data set? 20 Rows of Data set 1 or 15 Matching Rows?
Left Outer Join on Table 4 on
               4.M = 3.M
-- What will be data set? X Rows of Data set 2 or 10 Matching Rows?
Please have a look and clear my understanding.

I have two tables defined (below). Emp table has data and there is no data in Emp_Type table yet! Right now it is empty.
I want to write a query that returns data from both the tables even though there is no data in Emp_type table. I am using left outer join but it returning nothing. Anyone can help?
select *
from emp e
left outer join emp_Type t
on e.empid = t.empid
WHERE t.type_id = 1
and t.end_date is null;
The join is including all rows from emp, just like you want.
The WHERE clause is discarding all of those rows. Since all the columns from emp_type (alias t) are NULL, the condition "t.type_id = 1" in the WHERE clause is never true.
Perhaps you meant to include all those conditions in the join conditions, like this:
select *
from emp e
left outer join emp_Type t
    on e.empid = t.empid
   and t.type_id = 1
   and t.end_date is null;Edited by: Frank Kulash on Jan 30, 2012 3:56 PM

Left outer join query

Hi Experts,
    I am facing a problem with left outer join query. Am using one standard table and ztable for this join. My problem is values are not extracted from the Ztable.
Query:
      SELECT b~lifnr b~belnr b~gjahr b~xblnr b~shkzg b~blart b~zfbdt b~budat b~wrbtr
         b~wskto b~zlspr s~EXTRACT_STATUS s~maturity_date FROM bsik AS b
         LEFT OUTER JOIN zprm_rvne_sapdoc AS s
         ON s~belnr EQ b~belnr
         AND s~gjahr EQ b~gjahr
         INTO CORRESPONDING FIELDS OF TABLE it_join
            WHERE b~zlsch = p_zlsch
            AND b~xblnr IN so_invno
            ORDER BY b~lifnr b~xblnr.
I have all entries of BSIK table in Ztable with extract status as Y but this query is not fetching extract status and maturity date of ztable so it is blank in the internal table.
Need solution.

Hi,
see the sample wiki for writing the Left outer join
http://wiki.sdn.sap.com/wiki/display/Snippets/EmployeeInfotype0000to9999ChangeHistory
Specifying Two or More Database Tables as a Left Outer Join
The left outer join, on the other hand, reads lines from the left-hand database table or join even if there is no corresponding line in the right-hand table.
SELECT...
FROM <tab> LEFT [OUTER] JOIN <dbtab> [AS <alias>] ON <cond>
       <options>
<tab> and <dbtab> are subject to the same rules and conditions as in an inner join. The OUTER addition is optional. The tables are linked in the same way as the inner join with the one exception that all lines selected from <tab> are included in the final selection. If <dbtab> does not contain any lines that meet the condition <cond>, the system includes a single line in the selection whose columns from <dbtab> are filled with null values.
In the left outer join, more restrictions apply to the condition <cond> than in the inner join. In addition to the above restrictions:
EQ or = is the only permitted relational operator.
There must be at least one comparison between columns from <tab> and <dbtab>.
The WHERE clause may not contain any comparisons with columns from <dbtab>. All comparisons using columns from <dbtab> must appear in the condition <cond>.
If we have two tables named stud1,stud2 with the following data
Stud1: id Name stud2: id Name
1 xxx 1 aaa
2 yyy 2 bbb
3 zzz 4 ccc
4 www 6 ddd
When we use Left Outer Join we get the output as:
1 aaa
2 bbb
3 <Null>
4 ccc
When we use Right Outer Join we get the output as:
1 aaa
2 bbb
4 ccc
<Null> ddd
When we use Full Outer Join we get the output as:
1 aaa
2 bbb
3 <Null>
4 ccc
<Null> ddd

Error in making left outer join to a nested query

i am writing this query getting error here i am using nested query with that i am making join it is giving error

give me and suggestion

i am using left outer join at virtual table say x your gave me its equivalent
EXISTS (SELECT 1 FROM IvItemGenericLink G
WHERE G.ITEMID =V.ID
AND G.GenericId = L.GenericId)-----its i guess inner join
i am not confirmed that why iam asking this i guess i have to use this
as i use keyword inner join for inner join and for left join i use
left outer join
EXISTS (SELECT 1 FROM IvItemGenericLink G
WHERE G.ITEMID =V.ID
AND G.GenericId(+) = L.GenericId)-----its i guess left outer join
left outer join
Select GenericId from

is this equivalent to left outer join
