Nested query / Rank in ODI 10g?

How can be an nested query with analytical function (RANK() OVER) can be implemented in ODI 10g without using an external view?
SELECT field1, field2, field3, field4, field5, field6, field7
FROM
         (SELECT
          RANK() OVER (PARTITION BY table1.field1, table1.field2, table1.field3 ORDER BY table1.field4 , table1.field5) alias_rank,
          field1, field2, field3, field4, field5, field6, field7
                FROM table1
          ) subset_alias
WHERE subset_alias.alias_rank=10)

Query Regarding Updation/Migration of ODI 10g To ODI 11g.

Hi All,
Currently I am using ODI 10g Version & Repositories ( Work & Master) have been installed on Oracle database version "Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi"
We are thinking to migrate from ODI 10g to ODI 11g Version 11.1.1.5 & i have some queries which are metioned below.
1. Can we install ODI 11g Version 11.1.1.5 version with Repositories ( Work & Master) on Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi" or do i need to upgrade my database version to 11G?.
2. If yes then, Can i upgrade or use exting Repositoires ( 10g one) for ODI 11g OR i have to create new Repositoires & move/migrate the objects of 10G repositories as mentioned in the Oracle installation doc.
3. Currently I am using OBIEE 10g for reposrting purpose & if i switch to ODI 11g , Do i need to use OBIEE 11g?
ODI gurus, I need your reponse ASAP & i have to share it on urgent basis.
Thanks

refer http://docs.oracle.com/cd/E23943_01/upgrade.1111/e12642/tasklist.htm#CIHGIDFG
2. If yes then, Can i upgrade or use exting Repositoires ( 10g one) for ODI 11g OR i have to create new Repositoires & move/migrate the objects of 10G repositories as mentioned in the Oracle installation doc.No need to create new repositories. You just upgrade them. But you need to takecare of certain things as you are a 10g user. Refer below link for the prerequisite
http://docs.oracle.com/cd/E23943_01/upgrade.1111/e12642/prevusers.htm
3. Currently I am using OBIEE 10g for reposrting purpose & if i switch to ODI 11g , Do i need to use OBIEE 11g?Not clear about the question ?

ODI 10G getPAckage()

Hi ,
I want to write a procedure like this:
DECLARE
CURSOR C IS
SELECT table_name FROM ALL_TABLES WHERE table_name LIKE 'TMP_<%=odiRef.getPackage("PACKAGE_NAME")%> %' AND owner='STG';
R C%ROWTYPE;
BEGIN
OPEN C;
LOOP
FETCH C INTO R;
EXIT WHEN C%NOTFOUND;
BEGIN
STG.DROP_TABLE(R.TABLE_NAME);
EXCEPTION WHEN OTHERS THEN
NULL;
END;
END LOOP;
CLOSE C;
END;
But I guess it desn't exists odiRef.getPAckage("PACKAGE_NAME") method in odi 10g.How can ı get packagename ?
Thx a lot

If I understand, you've created an ODI procedure. And you have inserted this procedure as a step of an ODI package.
And you want to retrieve the name of the package that contains this procedure.
Is that right ?
If so, you can find the name of the package that use this procedure by using a query on the work repository.
Here's the query :
select pack.pack_name as PACKAGE
FROM
odi_work.SNP_PACKAGE Pack
inner join odi_work.SNP_STEP step on step.i_package = pack.i_package
inner join odi_work.snp_trt proc on proc.i_trt = etape.i_trt
WHERE proc.trt_name='enter the name of your procedure'
You can write this query on the "SQL on source" tab of your procedure. And use the result on the "SQL on target" tab.
In "target tab", you can write something like that :
SELECT table_name FROM ALL_TABLES WHERE table_name LIKE 'TMP_:PACKAGE%> %' AND owner='STG';
If you don't want to enter the name of procedure manually, I assume you can also retrieve it with "<%=odiRef.getStep("STEP_NAME")%>" method. But your step must have the same name than your procedure (this is the default behaviour)

How to do a Nested Query ?

I have three Tables Student, Courses, Marks
Table : Student
Columns
StudentID <PK>
First Name
Last Name
Table : Grades
Columns
StudentID <FK>
Grade
Table : Courses
Columns
StudentID <FK>
CourseID
CourseDesc
Now to get all the course descriptions which this particular student is taking based on the StudentID we do something like this :
SELECT c.courseDesc
FROM Courses c, Student s
WHERE s.StudentID = '100'
AND s.StudentID = c.StudentID
The above will work
But If I need to do it in nested query how can I do it : Something like
SELECT * FROM
SELECT c.courseDesc
FROM Courses c, Student s
AND s.StudentID = c.StudentID
WHERE s.StudentID = '100'
Thanks for the help.
Harsimrat

oops,try this...
SELECT * FROM (
SELECT s.StudentID,c.courseDesc
FROM Courses c, Student s
WHERE s.StudentID = c.StudentID)
WHERE StudentID = '100';
SQL> select * from
2 (select e.ename,d.deptno from test_dept d,test_emp e where e.deptno = d.deptno)
3 where deptno = 10;
ENAME DEPTNO

Using nested query to avoid repeated object traversal

Hi everyone,
My SQL is still very basic, hopefully this is not a dumb question ;-)
I have a table with a single spatial column of type SDO_GEOMETRY:
SQL> desc WITHIN_POINT_DISTANCE_TAB
Name                                            Null?    Type
POINT                                                    MDSYS.SDO_GEOMETRYin which I store only single point geometries. I discovered that using the min/max SQL operators to get the combined extend of my points is faster than using SDO_TUNE.EXTEND_OF:
SQL> select min(e.point.sdo_point.x) min_x, max(e.point.sdo_point.x) max_x, min(e.point.sdo_point.y) min_y, max(e.point.
sdo_point.y) max_y from WITHIN_POINT_DISTANCE_TAB e;
     MIN_X      MAX_X      MIN_Y      MAX_Y
-44.700001 737.400024 -23.870001 1094.83008
Elapsed: 00:00:00.01but it bothers me a bit to repeat e.point.sdo_point 4 times in the above (what can I say, I'm a developer ;-) So I thought I could use a nested query to select all the SDO_POINT_TYPE sdo_point's and refer it using a p alias, and be able to simplify the query to:
SQL> select min(p.x), min(p.y), max(p.x), max(p.y) from (select t.point.sdo_point from WITHIN_POINT_DISTANCE_TAB t) p;
select min(p.x), min(p.y), max(p.x), max(p.y) from (select t.point.sdo_point from WITHIN_POINT_DISTANCE_TAB t) p
ERROR at line 1:
ORA-00904: "P"."Y": invalid identifierBut obviously this is incorrect, yet I'd like to understand what I'm missing here.
I posited that maybe the sub-query can't return an object member and needs to return a column, but that doesn't appear to be the case:
SQL> select min(p.sdo_point.x), min(p.sdo_point.y), max(p.sdo_point.x), max(p.sdo_point.y) from (select t.point from WIT
HIN_POINT_DISTANCE_TAB t) p;
select min(p.sdo_point.x), min(p.sdo_point.y), max(p.sdo_point.x), max(p.sdo_point.y) from (select t.point from WITHIN_P
OINT_DISTANCE_TAB t) p
ERROR at line 1:
ORA-00904: "P"."SDO_POINT"."Y": invalid identifierCan someone please explain why the nested query approach fails as written above?
More generally, is it a bad idea to go for a nested query just for syntactic reasons? Are there performance implications going the nested query route above? (I actually wanted to see the perf. implications experimentally, but since it fails I can't...)
Any insight would be appreciated. Thanks, --DD

Thank you Peter. I now understand that I need to alias the column in addition to the table (the latter only because I traverse objects which require table aliases).
SQL> select min(t.p.x), min(t.p.y), max(t.p.x), max(t.p.y) from
2 (select nt.point.sdo_point p from WITHIN_POINT_DISTANCE_TAB nt) t;
MIN(T.P.X) MIN(T.P.Y) MAX(T.P.X) MAX(T.P.Y)
-44.700001 -23.870001 737.400024 1094.83008
Elapsed: 00:00:00.01Performance-wise it looks similar, but I need to test on a bigger table because it's too fast with 10K points to show differences. Overall it doesn't look that using the nested query syntax makes the query more readable once all pieces to make it work are there.
Thanks again, --DD
PS: Just aliasing the column and not the outer table fails:
SQL> select min(p.x), min(p.y), max(p.x), max(p.y) from (select nt.point.sdo_point p from WITHIN_POINT_DISTANCE_TAB nt);
select min(p.x), min(p.y), max(p.x), max(p.y) from (select nt.point.sdo_point p from WITHIN_POINT_DISTANCE_TAB nt)
ERROR at line 1:
ORA-00904: "P"."Y": invalid identifier

Implement MAX / JOIN in ODI 10g?

What is the approach for using MAX functions in ODI 10g? I need it to filter source data:
SELECT SRC_TAB.*
FROM SRC_TAB
INNER JOIN
(SELECT MAX(COL1) COL1, COL2 FROM SRC_TAB GROUP BY COL2) B
ON SRC_TAB.COL1=B.COL1 AND SRC_TAB.COL2 = B.COL2
Luckily this issue has been addressed in ODI 11g.
Thank you.

That's not good especially when you have large volume of data.
In this case, in 10g it's better to rely on a underline view rather than 2 interfaces.

ODI 10g - session keep a table locked

Hi,
We have a random issue, with ODI session that keep a lock on a table, even replication is finished and session becomes inactive
It generated dead locks as a trigger has to update the target table.
what happened :
- user application create rows (13)
- ODI scenario replicate the rows (contract table)
- 2nd scenario based on same source with another sunscriber run a stored procedure to create records in another table (around 30, positions table)
this 2nd locked the target table, and when the run of the procedure finished, and commited, the lock was not released
- ODI replicate another table (price) 30mn later, a trigger on target update position table with new values
---> trigger failed with deadlock (ora 60)
---> ODI failed as the trigger raised back the error
this issue happened after 10 hours of same activity without issue, chained lot of time, but suddenly the lock become persistent (more than 4 hours)
what can I do?
use ODI 10g 10.1.3.5.0 - RDBMS 10.2.0.4

Hi !
For small tables wich are mostly accessed with full table scan you can use
ALTER TABLE <table_name> STORAGE (BUFFER_POOL KEEP);KEEP pool should be properly sized , setting will cause once the table is read oracle will avoid flushing it out from pool.

Heavu CPU Utilization of Dictionary Query - After 9i to 10g Upgrade

Hi Friends,
We have migrated our production DB from Oracle 9i(Windows) to Oracle 10g(AIX) and after that a heavy cpu utilization query is coming frequently and hence many timeouts are happening in the application.
Application is connecting to the database through Java Application (JDBC).
Once the application service is started, below query is invoked and CPU takes around 20% continuously.
The interesting thing is this query is not owned by the application schema but by SYS and it's invoked from Application Schema.
We have raised an SR but still no luck.
Any help will be very much appreciated.

Problem when exporting and importing project from odi 10g to odi 11g

Hi,
I want to migrate my project from odi 10g to odi 11g.
But when i am importing the interface then it is giving the error of mising references .
I have exported the project(without its child component),models
(including my datastore),KM's,folder (without its child component),packages(with child components),interaces(with child components),procedures(with child components),variables from odi 10g.
After exporting all these objects i imported all the objects with import type set as "Synonym mode insert" into odi 11g but when i imported the interface it is giving the error of missing references.
Source technolgy is Oracle and target technolgy is Postgres.
Topologies have been made in the ODI 11g same as in ODI 10g.
Please help.

You dont need to migrate the complete repository. You can migrate a project at a time into ODI 11.1.1.5.x
You have to be careful while importing. You have to follow a sequence when importing.
Empty Project -> KMs -> Models (with DB Stores) -> Variable -> Empty Folders -> Interfaces -> Procedures -> Packages ---- All in SYNONYM mode insert (no exceptions)
And your repository id in 11g MUST be different from the one in 10g.

Count(*) with nested query

Hi,
I have a question about the count(*) with nested query.
I have a table T1 with these columns:
C1 number
C2 number
C3 number
C4 number
C5 number
(The type of each column is not relevant for the example.)
This query:
select C1, C2, C3, C4
from T1
group by C1, C2
it's not correct becausa C3 and C4 are not columns specified in the GROUP BY expression.
If if run this query:
select count(*)
from (select C1, C2, C3, C4
from T1
group by C1, C2)
I haven't an error message (the result is correctly the number of records).
Why?
Thanks.
Best regards,
Luca

Because you are just selecting count(*) and none of the columns from the subquery, Oracle is optimising it by ignoring the selected columns and just running the sub query with the group by columns. I know it seems odd, but if you take a basic example:
SQL> ed
Wrote file afiedt.buf
1 select count(*)
2 from (select empno, sal, mgr, deptno
3 from emp
4* group by deptno)
SQL> /
COUNT(*)
3... all columns but deptno are ignored
... but if you include one of the other columns, even if you group by that column...
SQL> ed
Wrote file afiedt.buf
1 select count(*), empno
2 from (select empno, sal, mgr, deptno
3 from emp
4 group by deptno)
5* group by empno
SQL> /
group by empno
ERROR at line 5:
ORA-00979: not a GROUP BY expression
SQL>... the error returns, because you're forcing oracle to include the column in the subquery.
