Subquery in ODI

Hello,
i need an information ...
situation:
i need the NVL ( ..., ....) function.
in the developer it is no problem to test the subquery, but in ODI
i think, it's al little bit more complicated.
NVL( <value from my table>, <subquery> )
at the moment i've written the subquery "by hand"... i've written the complett SQL-Query into to NVL after the comma.
i think that this is not common.
can someone help me?
i'm not sure, should i use an user-function or an variable ? :-/
i'm pretty unsure..
best regards
Michael

Hi Michael
You can do this using the lookup component in ODI 11g. If you add your lookup table or temporary interface as the lookup table and set the 'SQL expression in the select clause' for the lookup, you can define your target expression to be NVL(EMP.SAL, BONUS.SAL) and ODI will generate the select statement for the lookup as a scalar subquery inline replacing the BONUS.SAL part of the expression.
Cheers

SQL expression in ODI

I Have the following interface in oracle data integrator
http://i44.tinypic.com/2mrsmxt.png
# it execute successfully before inserting the following expression
In the mapping I insert the following SQL expression to get the average when the quantity is 0
AVG(
CASE WHEN TEST.QUN = 0 THEN
(SELECT TEST.QUN FROM TEST
WHERE TEST1.PRUDU=TEST.PRUDU
AND TEST1.FLOW=TEST.UNIT
AND TEST1.UNIT=TEST.UNIT
AND to_char(TEST.DATEDDD,'MON')= to_char(TEST1.DATEDDD,'MON')
AND TEST1.DATEDDD !=TEST.DATEDDD
GROUP BY TEST.QUN
ELSE TEST.QUN
END)
when I check this expression in ODI ..
# the sql expression is correct for this RDMS
when I executed the interface i get this error
Caused By: java.sql.SQLSyntaxErrorException: ORA-00937: not a single-group group function
any idea ?

I changed the code a little ..
CASE WHEN TEST.QUN = 0 THEN
(SELECT AVG(TEST.QUN) FROM TEST
WHERE TEST1.PRUDU=TEST.PRUDU
AND TEST1.FLOW=TEST.FLOW
AND TEST1.UNIT=TEST.UNIT
AND to_char(TEST.DATEDDD,'MON')= to_char(TEST1.DATEDDD,'MON')
AND to_char(TEST.DATEDDD,'YYYY')!= to_char(TEST1.DATEDDD,'YYYY')
ELSE TEST.QUN
END
And I get this error ..
ORA-01427: single-row subquery returns more than one row tips.
The TEST Table from the source and TEST1 is a lookup table because I couldn't do the alais in ODI
In sql developer I did the following code that will do the same thing and work successfully ..
update test B
set B.qun=
(SELECT AVG(TEST.QUN) FROM TEST
WHERE TEST.FLOW=B.UNIT
AND TEST.UNIT=B.UNIT
AND TEST.PRUDU=b.prudu
AND TEST.FLOW=b.flow
AND to_char(TEST.DATEDDD,'MON')= to_char(B.DATEDDD,'MON')
AND to_char(TEST.DATEDDD,'YYYY')!= to_char(B.DATEDDD,'YYYY')
where B.qun=0;
any help ?

Help : How to use list of values in Variable in ODI

Dear All,
I have a multiple values in table, and I would to use these values a a parameter in ODI to retrieve rows based on these values. As I know that we can use single value in variable in ODI.
Any one can Help me please?

Can't you use a join between the tables ?
ODI mostly take advantage of native technologies.
i.e If my source technology is oracle then i will create a join between the table i.e. MAINTABLE.column = LOVTABLE.COLUMN and also put a filter on LOVTABLE to take required values.
OR you can write a subquery in the Filter i.e. MAINTABLE.COLUMN in ( Select LOVVALUES from LOVTABLE where LOVTABLE.ATTRIBUTE = 'BUSINESS_UNIT')

How can I move the ODI Work Repository from one server to another server?

How can I move the ODI Work Repository from one server to another server?

Hi,
If you would like to move your source models, target models and project contents from Work repository 1 to another work repository.
I.e. Dev. server to Prod Server.
1. Firstly, replicate the master repository connections i.e. with same naming conventions manually
2. Go to Dev. Server work repository -> File Tab -> Click on Export work repository (save it in a folder)
3. After exporting, you can view the xml files in the folders.
4. Now, Open the Prod. server and make sure you already replicated mas. rep. details.
5. Now, right click on model and import source model in synonym mode insert_update (select source model from the folder where your xml file located)
6. Similarily, import again target then Project.
Now, check. It should work.
Thank you.

Assigning a Jython variable value to an ODI variable

I have to implement database cursor functionality in ODI.
For storing the returned values from database, I am using a Jython list.
The next functionality that I have to implement is as follows:
(i) For each value in the Jython list, I have to pass that value as a variable to an interface and then execute the interface
(ii) Return back to the Jython list to get the next value in it
(iii) Execute the interface for the new value from Jython list
(iv) Have to execute the interface for as many values as in the list and stop when list is over.

Hi,
Thanks for your replies.
I tried your method of using source as a query in procedure and using ODI startScen in the Target of the same procedure. But the scenario runs only once, and then stops even though the Source query returns 4 rows.
Do we have to write Source and Target in separate steps of the procedure?
Does ODI store the many records returned into some internal variables?
I need to implement a cursor functionality so what is the best approach?
Can i pass array variable value to some odi variables and do a loop?
I used a workaround....it works but dont know if that's a good way of doing things:
I retrieved all the different values that I need in a string by appending the values(this was done using Java loop).
In my next step in the procedure I call a scenario(package which has some variables and my interface), which passes this long variable from Java as <@...@>
Then in the package I use an iteration variable which is used to find out the SubString position so that I can extract the correct string to use for my Interface in the next step of the Package.
It is working fine as of now.....but things could be made simpler if I could call the scenario in the Java loop, then I wouldn't need the iteration variable etc.

This error means that there is no value to assign to your variable, because specified query doesn't return result row. You should rewrite your query to guarantee that it would return row in any case.
For example, select nvl(min(b.res), -1) from (select (select CEIL((select count(1) from Table1)/2) - #SMARTS.loop_variable from dual) result from dual) a, (select CEIL((select count(1) from cst_dsa.m_pb_cable_data)/2) res from dual) b where a.result >= 0 group by a,b

Hi;
You have to login https://support.oracle.com/CSP/ui/flash.html and you have to CSI account.
This site is oracle site for tech. documents for can rise SR etc.. for more details please check Re: Installing Oracle Database 10.2.0.4
you need to customer support identifier which is called CSI for can login metalink(https://support.oracle.com/CSP/ui/flash.html)
If you dont have metalink account there is no way to see that doc.
Pretty simple process:
1) You purchase a perpetual or term license from Oracle;
2) At the beginning of the period, during the valid term you purchase
Support for the period (1 year);
3) Oracle sends you the CSI.

Can we preview data after RKM in SAP in ODI 11g

can we able to right click and view data in models after reverse engineering in SAP in ODI 11g ??
Edited by: Drona on Mar 16, 2012 1:06 PM

No we cannot preview the data as SAP connection is made using Jco adapter.
We can only preview the data for data servers which are connected using jdbc.

Thats obvious from the xml file contents you have given here. In this xml file You have four complex type. Two of them are employee and address. However the employee doesnot have any relation with address as you have not added the relationship. Thats why its failing. Its not the fault of ODI.
Also I would suggest not to use auto generated dtd by ODI as you might face problem in future. For example the address type of XML has 8 attributes and 4 of them are not mandatory. That means each of your xml file may have attributes between 4 to 8. This is where ODI auto generated DTD fails.
XML Schema complexType Element

Unable to configure ODBC data source through odi

Hi,
Let me explain the architecture first.
We have three machines
1. OpenVMS machine on which connx server is running for RMS files, say SRC
2. Windows machine on which ODI Data Studio 11.1.1, Say WRKSTN, This has connx client installed
3. Target is HP-UX on which SYBASE is running, say TRGT. On target we have installed connx client and ODI Stand alone agent and agnt01 is the name of the agent that is running
My Requirement is,
I need to pull the data from SRC and load it into TRGT using the ODI agent agnt01, through ODBC data connectivity.
If i configure DSN on my WRKSTN they the agnt01 is unable to identify. If i configure a DSN on HP-UX machine then i am not able to specify that in ODI Sun odbc: Jdbc bridge driver.
Kindly help me as to how i can resolve this
Thanks,
Rajesh H

Configuring DSN on windows workstation would not help as the agent is not running on that machine. The DSN has to be configured on the machine where the agent is running on which you want to execute the flow. What error are you getting on trying to specify the DSN name on HPUX in the data server jdbc url?

Hi,
The cursor has a different parameter? Maybe the query is not exactly the same. Could you check this?
This is your query (formatted):
SELECT DISTINCT PSE.PARENT_POSITION_ID,
                (SELECT DISTINCT PPD1.SEGMENT2
                   FROM PER_POSITION_DEFINITIONS   PPD1,
                        HR_ALL_POSITIONS_F         HAPF2,
                        PER_POS_STRUCTURE_ELEMENTS PSE2
                  WHERE TRUNC(SYSDATE) BETWEEN HAPF2.EFFECTIVE_START_DATE AND
                        HAPF2.EFFECTIVE_END_DATE
                    AND PPD1.POSITION_DEFINITION_ID = HAPF2.POSITION_DEFINITION_ID
                    AND HAPF2.POSITION_ID = PSE2.PARENT_POSITION_ID
                    AND PSE2.PARENT_POSITION_ID = PSE.PARENT_POSITION_ID
                    AND ROWNUM = 1) SEGMENT2,
                (SELECT DISTINCT PAPF1.FIRST_NAME || ' ' || PAPF1.LAST_NAME CHIEF_NAME
                   FROM PER_ALL_PEOPLE_F      PAPF1,
                        PER_ALL_ASSIGNMENTS_F PAAF1
                  WHERE TRUNC(SYSDATE) BETWEEN PAPF1.EFFECTIVE_START_DATE AND
                        PAPF1.EFFECTIVE_END_DATE
                    AND TRUNC(SYSDATE) BETWEEN PAAF1.EFFECTIVE_START_DATE AND
                        PAAF1.EFFECTIVE_END_DATE
                    AND PAAF1.POSITION_ID = PSE.PARENT_POSITION_ID
                    AND PAPF1.PERSON_ID = PAAF1.PERSON_ID

   AND HAPF.POSITION_ID = PSE.SUBORDINATE_POSITION_ID
   AND HAPF.POSITION_DEFINITION_ID = PPD.POSITION_DEFINITION_ID;Tips: To put formatted code you must use {noformat}{noformat} tags, start tag and end tag are the same,you don't need to put '/' in the close tag.

Subquery in IF statement in trigger, without using foreign keys

Hello,
I'm investigating ways of writing a subquery in an IF statement, which is placed inside a trigger.
I wanna write smth like IF (:new.jazz not in (select goldies from T where ... )) etc. I don't know whether the fact that the IF is in a trigger adds some additional restrictions. (Does it?)
So far I found the solution described here: SubQuery Comparison in If Statement which I find a bit tacky, I could have the 'cooleststarinthegalaxy' instead of 1 and seems you need to do extra light, but still extra lifting.
I also read about the possibility of using MERGE, which I'm currently researching.
Is there any other way?
Thanks

Edite by me: the question is how (if possible) to do this without a foreign key.

Hi,

Say I have tables A(namea varchar(10)), B(nameb varchar(10)), and B contains tuples ('1stname','2ndname').
I wrote a trigger before insertion, for each row, on table A. For a tuple t to be inserted, it should check whether t.namea is in the set of values nameb from B.
E.g., INSERT INTO A VALUES('1stname') should work. But INSERT INTO A VALUES ('3rdname') should fail. You can use a foreign key constraint for that.
If the tables already exist, and b.nameb is declared as UNIQUE (or PRIMARY KEY), then you can say:
ALTER TABLE a
    ADD CONSTRAINT     a_namea_fk
    FOREIGN KEY (namea)
    REFERENCES b (nameb)
;If you had a situation where you really needed to query a table in PL/SQL, and you weren't sure if the query would find anything, you could put the query in its own BEGIN ... EXCEPTION block, and test for NO_DATA_FOUND.
If you're just checking to see if a row exists or not, you can always write a query that is guaranteed to return exactly 1 row, like this:
BEGIN
    SELECT COUNT (*)
    INTO    x
    FROM    b
    WHERE   nameb = :NEW.namea
    AND         ROWNUM = 1;
    IF x = 0
    THEN
        ...        -- print msgs, raise exceptions etc
    END IF;
