Left Join in a View

I'm using a left join in a view object but I get ORA-00942 Table or View does not exist.
When I run the SQL Query in SQLDeveloper, it works fine. But when I use it in my ViewObject, I get the error. The Query looks like this (It is more difficult than this, but this is the part that I get the error in)
SELECT LocationHistory.LOCATION_HISTORY_ID,
LocationHistory.CONFIG_ITEM_ID,
LocationHistory.EMPLOYEE_ID,
LocationHistory.STD_LOCATION_ID,
LocationHistory.FROM_DATE,
LocationHistory.DESCRIPTION,
StandardLocation.STANDARD_LOCATION_ID AS STANDARD_LOCATION_ID1,
StandardLocation.NAME,
StandardLocation.DESCRIPTION AS DESCRIPTION1
FROM HSR_LOC_HISTORY LocationHistory
LEFT JOIN HSR_STD_LOCATION StandardLocation
ON LocationHistory.STD_LOCATION_ID = StandardLocation.STANDARD_LOCATION_ID
WHERE STD_LOCATION_ID = 20
Does anyone know what the problem could be? Thanks for the help in advance

Hi,
It looks like the VO validation thinks LEFT is a table (table or view does not exist)
try
FROM HSR_LOC_HISTORY LocationHistory,
HSR_STD_LOCATION StandardLocation
WHERE LocationHistory.STD_LOCATION_ID = StandardLocation.STANDARD_LOCATION_ID(+)
AND STD_LOCATION_ID = 20much easier to read and understand particularly if you have multiple outer joins.

How to do a left join to create a timesheet status report in Power View

I am trying to create a very simple report in power view for Project Online. It's a timesheet status report that should show a list of resources, and the current status of their timesheet (in progress, not started, etc).
In Excel, I created an odata connection with Resources and Timesheets, and set up the connection between them. So, I can now easily display a list of timesheets, and filter them by end date. Good. But this only displays rows where there is an existing timesheet.
So resources who have not started a timesheet are not displayed. So, I need a "left join" in power view to display all resources, whether or not they have a timesheet for the period. (and, for the ones that do, I need to display fields from the timesheet,
such as the status description.)
Any suggestions?
Mike G.

Hi Mike,
I'm not sure of what I'm suggesting since I got no instance to test it, but I'm wondering if the OLAP Cube "MSP_Project_Timesheet" wouldn't contain all resources of the enterprise pool with assignments (and not only resources that already submitted
a timesheet) since it is a combination of the assignment timephased, resource timephased and EPM timesheet cubes.
Hope this helps.

How to create a left join view in se11??

I would like to create a view which contains KNA1,KONA,KNVV,KNVH(four tables) , I want to use this view to create a search help for Tcode 'VBO3'.
but when I join table KNVH, there is no data in view, because there is no customer hierarchy, so I want to create a left join view. could you please tell me how to create a left join view? Thank you very much.

Hello,
yes, in general, maint. view and help view could be created as outer join view.
but it should obey relationship.
my fourt tables:
KONA -
> I want to get agreement number and type from this table
KNA1 -
>I want to get customer name, city, country from this table
KNVH -
>I want to get customer hierarchy from this table.
KNVV -
>I want to get customer group 1 from this table.
but in help view, I can only get relationship between KONA and KNA1.
I could not find the relationship for KNVH and KNVV.
if it's required to add a search help exit, then how to write the code in the function?
Could somebody please give me any solutions? thank you.

Multi-Left Join Query Tuning

I am tuning a SELECT query with 36 Left Joins in addition to normal Inner Joins and a View.
I have used the RESULT_CACHE hint with some success.
I have tried the LEADING hint and USE_MERGE with no success.
Is there an Undocumented HINT and that may assist me?
Thanks

Hi, Brad,
Welcome to the forum!

Post a simplified version ot the problem (with maybe 3 tables that need to be outer-joined). Post CREATE TABLE and INSERT statements for a little sample data (relevant columns only), the results you want from that sample data, and an explanation of how you get those results from that data.

Left join query with join of three tables

I'm trying to build a query which has me stumped. Most of the query is fairly straightforward but I've run into an issue I'm not sure how to solve.
Background:
We have actions stored in i_action.
We have the available attributes for each type of action. The available attributes for each action are described in shared_action_attribute. Each type of action may have up to three attributes or none at all.
We have the values stored for the attributes in i_attribute_value.
A written example:
We have a transfer action (action_code B4). The entry of the B4 action into i_action records the fact that the transfer occurred and the date on which it occurred. The available attributes for a transfer action are the receiving function code, the receiving unit number, and the transfer reason code. These available attribute types and their order are stored in shared_action_attribute. The actual values of the attributes for a specific transfer action are stored in i_attribute_value.
Now i_action and i_attribute_value can be directly linked through action_seq in i_action and ia_action_seq in i_attribute_value. A left join built between these two tables provides results for all actions (including actions which have no attributes) and attribute values (see query 1 below).
There are two issues. First, I only want the first two attributes. In order to specify the first two attributes, I also have to link i_attribute_value to shared_action_attribute (which is where the order is stored). I can build a simple query (without the left join) linking the three tables but then actions with no attributes would be excluded from my result set (see query 2 below).
The second issue is that I would actually like one row returned for each action with first_attribute and second_attribute as columns instead of two rows.
The final query will be used to create a materialized view.
Here are the tables and examples of what's stored in them:

I found this pretty complex to try to write out - I hope I've been clear.
Thanks so much!

Ok, here's more information with a simplified question. I figured out the syntax for building my query with the three tables. My final query returns multiple rows (multiple attributes per action). Instead of multiple rows, I'd like two columns (first_attribute, and second_attribute) in a single row (I only need the first two attributes).
Here's the action table:

LEFT JOINING with a string?

I'm viewing code where the person left joined a column with a string.
   lu_ods.lookup_type(+) = 'FORX_ORDERPRO_ACTION'Is this just bad coding. Is there any reason why someone would do this?
Doesn't
   lu_ods.lookup_type = 'FORX_ORDERPRO_ACTION'work just as well?

As Sentinel said, it can change the result if you are left joining between two tables:
with a as (
select 1 num, 'a' col from dual UNION ALL
select 2 num, 'b' col from dual UNION ALL
select 3 num, 'c' col from dual
b as (
select 1 num, 'a' col from dual UNION ALL
select 4 num, 'e' col from dual UNION ALL
select 5 num, 'f' col from dual
select *
from a, b
where a.num(+) = b.num
and a.num(+) = 1;

WHERE CAA.NODE_APP = :WHICHAPP and CAA.REMOVE_DT is NULL)
LOOP
dbms_output.put_line(i.THENODE||'--'||i.CNFFT||' ');
END LOOP;
END;
When this returns there is a row for each of the left joins.
server1--CPUCount 
server1--ContactInfo 
server1--ContactInfo 
server1--ContactInfo

What I would like to do it just have one row:

Hi,
Taking 1 column from N rows, and transforming that into N columns on 1 row is called Pivoting.

Left joins : Case or if statement

Hi
I want to know if one can build in a case or if statement into a left join. I want to multiply a value with -1 if the condition is met.

I think it is not possible in SELECT statement...but you can do the below to resolve it.
add a field for FKART in your internal table.
TYPES: BEGIN OF tab ,
       kunag LIKE vbrk-kunag,
       fkdat like vbrk-fkdat,
       matnr LIKE vbrp-matnr,
       werks LIKE vbrp-werks,
       fkart like vbrk-fkart,
       volum LIKE vbrp-volum,
       END OF tab.
DATA: wa_outtab TYPE table of tab WITH HEADER LINE.
SELECT akunag afkdat
       bmatnr bwerks a~fkart
       SUM( b~volum )
   INTO table wa_outtab
FROM vbrk AS a
INNER JOIN vbrp AS b
      ON avbeln = bvbeln
WHERE
avbeln = bvbeln
AND ( afkart LIKE 'F2' OR afkart LIKE 'RE' )
GROUP BY akunag afkdat bmatnr bwerks a~fkart.
sort wa_outtab.
Loop at wa_outtab.
if wa_outtab-fkart = 'RE'.
    lpos = lpos + wa_outtab-volum.
else.
    lneg = lneg + wa_outtab-volum.
endif.
at end of werks.
     lvaule = lpos - lneg.
    lpos = lneg = 0.
endat.
endloop.

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

Hi,
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 joins on multi-million rows

i have a simple query doing left joining on several tables, upward of 7 tables. each table has several hundred million rows.
tblA is 1:M tblB and tblB is 1:M tblC and so on.
how to tune a query liked that?
sample query is
select distinct
a.col,b.col,c.col
from tblA a left join tblB b
on a.id=b.id
and a.col is not null
left join tblC
on b.id=c.id
and c.col > criteria
thanks.

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.

SharePoint 2013---How to convert current left Navigation into tree view

Hi All,
I want to convert current left navigation into tree view in SharePoint 2013. When we click on Modify Navigation and set headers and links; I need that should be convert into tree view. All headers should be expandable to thier links.
I just want tree view on navigation headers and links. not for all site and subsites which we can enabled from site settings --> Modify All Site settings --> Tree view
Please help me Master Page editing on Navigation Generation.. Thanks in advance!
Regards,
Anna

Hi Anna,
If you want to replace the Quick Launch part with the custom treeview web part in master page, you can comment out or remove the quick launch code block "",
then insert the custom web part snippet code in proper location in seattle master page, then all pages inheriting the seattle master page will have this web part.
Note, please back up the master page before customizing the original master page for recovery.

How to generate a query involving multiple tables(one left join others)

Hi, all,
I want to query a db like these:
I need all the demographics information(from table demo) and their acr info(from table acr), and their clinical info(from table clinical), and their lab info(from table lab).
The db is like this:
demo->acr: one to many
demo->clinical info: one to many
demo->lab info: one to many
I want to get one query result which are demo left join acr, and demo left join clinical, and demo left join lab. I hope the result is a record including demo info, acr info, clinical info, and lab info.
How could I do this in SQL?
Thanks a lot!
Qian

Thank you very, very much!
Actually, I need a huge query to include all the tables in our db.
We are running a clinical db which collects the patients demographics info, clinical info, lab info, and many other information.
The Demographics table is a center hub which connects other tables. This is the main architecture.
My boss needed a huge query to include all the information, so others could find what they need by filtering.
As you have found, because one patients usually has multiple clinical/lab info sets, so the result will be multiplied! the number of result=n*m*k*...
My first plan is to set time point criteria to narrow all the records with one study year. If somebody needs to compare them, then I have to show them all.
So I have to know the SQL to generate a huge query including as many tables as possible.
I show some details here:
CREATE TABLE "IMMUNODATA"."DEMOGRAPHICS" (
"SUBJECTID" INTEGER NOT NULL,
"WORKID" INTEGER,
"OMRFHISTORYNUMBER" INTEGER,
"OTHERID" INTEGER,
"BARCODE" INTEGER,
"GENDER" VARCHAR2(1),
"DOB" DATE,
"RACEAI" INTEGER,
"RACECAUCASIAN" INTEGER,
"RACEAA" INTEGER,
"RACEASIAN" INTEGER,
"RACEPAC" INTEGER,
"RACEHIS" INTEGER,
"RACEOTHER" VARCHAR2(50),
"SSN" VARCHAR2(11),
PRIMARY KEY("SUBJECTID") VALIDATE
CREATE TABLE "IMMUNODATA"."ACR" (
"ID" INTEGER NOT NULL,
"THEDATE" DATE ,
"SUBJECTID" INTEGER NOT NULL,
"ACR_PAGENOTCOMPLETED" VARCHAR2(1000) ,
"ACR_MALARRASHTODAY" INTEGER ,
"ACR_MALARRASHEVER" INTEGER ,
"ACR_MALARRSHEARLIESTDATE" DATE ,
PRIMARY KEY("ID") VALIDATE,
FOREIGN KEY("SUBJECTID") REFERENCES "IMMUNODATA"."DEMOGRAPHICS" ("SUBJECTID") VALIDATE
CREATE TABLE "IMMUNODATA"."CLIN" (
"ID" INTEGER NOT NULL,
"THEDATE" DATE ,
"SUBJECTID" INTEGER NOT NULL,
"CLIN_PAGENOTCOMPLETED" VARCHAR2(1000) ,
"CLIN_FATIGUE" VARCHAR2(20) ,
"CLIN_FATIGUEDATE" DATE ,
"CLIN_FEVER" VARCHAR2(20) ,
"CLIN_FEVERDATE" DATE ,
"CLIN_WEIGHTLOSS" VARCHAR2(20) ,
"CLIN_WEIGHTLOSSDATE" DATE ,
"CLIN_CARDIOMEGALY" VARCHAR2(20) ,
PRIMARY KEY("ID") VALIDATE,
FOREIGN KEY("SUBJECTID") REFERENCES "IMMUNODATA"."DEMOGRAPHICS" ("SUBJECTID") VALIDATE
Other tables are alike.
Thank very much!

Times missing in left column in week view

I am using iCal 2.0.3 and the hour times to not show in the left column in week view. Noon is present, but no others. There have been a few occasions that times have shown up, but then the next time they are gone. I set up a new user and went into iCal and the dates show. All my prefs are the same in my account and the "new user".
I am suspecting that there is corrupted prefs file of some sort, but I am reluctant to just delete files without knowing which one. Since I installed 10.4 a few months ago, I have found a lot of settings changed that upgrades should have kept intact in preferences.
Any suggestions?
