How to Avoid Self Join

Hi
Assume I have following table
Id Code
1 aa
1 bb
1 cc
2 bb
2 cc
The records will be grouped by Id. I want to find out group containing code say 'aa' and 'bb'.
Is it possible to obtain the desired result in a single query without using Self join?
Regards
~Pravin

This is a little clumsy....Anyway try it:
WITH t AS
(SELECT 1 id,'aa' code FROM dual
UNION ALL
SELECT 1,'bb' FROM dual
UNION ALL
SELECT 1,'cc' FROM dual
UNION ALL
SELECT 2,'bb' FROM dual
UNION ALL
SELECT 2,'cc' FROM dual)
SELECT id FROM t
WHERE code IN('aa', 'bb')
GROUP BY id HAVING COUNT(*) = 2;

How to write self join in sql?

Hi,
I have table named "table_upload", column "record_type" value "01,03,04....." and start_date,end_date and so on
And i will have value for start_date,end_date only for record_type=01,rest of type these two columns will be null.
now i need to write query with self join, to include above concept. can any one please help me .
and my query look like follows,

I just want to re write
Please provide DDL+DML + expected output!
and short explanation what is it that we all ask you for:
DDL = Data Definition Language. In our case that is, CREATE TABLE statements for your tables and other definitions that are needed to understand your tables structure and there for let us to test and reproduce the problem in our server. Without DDL no one
can execute any query.
How to get DDL: Right click on the table in Object Explorer and select script table as CREATE. Post these create table scripts here.
DML = data manipulation language is a family of queries used for manipulating the data it self like: inserting, deleting and updating data. In our case we need some sample data in order to check the query and get result, so we need some indert query for
sample data.
If you post a "create table query" for the tables and "insert <table> query" with some sample, then we could help you without Assuming/Guessing. There is a reason that DDL is generally asked for and expected when discussing query problems - it helps
to identify issues, clarify terminology and prevent incorrect assumptions. Sample data also provides a common point of reference for the discussion. A script that can be used to illustrate or reproduce the issue you have, will encourage others to help.

[JPA] How to avoid excessive joins in queries on InheritanceType.JOINED

Hi,
Let me use an over-simplified example to illustrate my question:
Let's assume I have two classes: SuperClass and SubClass. As the name suggests, SubClass extends SuperClass.
I have mapped them in JPA via:
@Inheritance(strategy=InheritanceType.JOINED)
@DiscriminatorColumn(name="CTYPE", discriminatorType=DiscriminatorType.INTEGER)
@PrimaryKeyJoinColumn(name="ID")And now let's suppose I run the following query:
Query q = entityManager.createQuery("select o.id from SubClass o");In this case, TopLink Essentials generates SQL with a join between the base table and the detail table. Why? All I need is the ID which is available in the detail table too. The base table doesn't need to be included in the query.
Is there a way to avoid the unnecessary join? I even tried mapping the ID column in both entities but it didn't help.
Best regards,
Bisser

Thank you for you reply, Doug!
I don't want to instantiate SubClass. I only wish to get the ID. I don't need validations or fields from the superclass.
Should I resort to using native SQL for that?
(By the way, the real query that I use in my program instantiates a completely different entity. I use the SubClass in a subquery. And I don't need the SuperClass to get involved. I have a foreign key that guarantees that the SuperClass's row exists in the database.)
Best regards,
Bisser

Before even starting to see why there is a performance problem, I think you should consider the fact that there is logical problem in your WHERE clause. According to what you mentioned the primary key is composed of *(c_date, iid, active)* yet iid is absent in both the global query's WHERE clause and also that of the subquery.
Consequently the (aggregate) rows in the subquery will not be linked based on a correct logic to the external query.

It is always helpful to provide the following:
1. Oracle version (SELECT * FROM V$VERSION)
2. Sample data in the form of CREATE / INSERT statements.
3. Expected output
4. Explanation of expected output (A.K.A. "business logic")
5. Use \ tags for #2 and #3. See FAQ (Link on top right side) for details.

Self join with fact table in Obie 10G

I am a newbie to obiee.I have a development requirement as follows-
I need to find supervisors designation with the existing star RPD design. explanation is below
                                                    DIM_Designation(Desig_Wid)
                                                  |(Row_wid)
                                                  |
DIM_EMPLOYEE--------WORKER_FACT------------DIM_Supervisor
(Row_Wid)-----------------(Employee_Wid)
                                  (Supervisor_Wid)------------(Row_Wid)
3 dimension is joined to fact to get employee, his supervisor and designation of employee. now i want to get the supervisor's designation? how is it possible? already employee and supervisor dimension is same W_employee_d table joined with fact as alias DIM_EMPLOYEE and DIM_SUPERVISOR. how to do self join with fact to get supervisor's designation. i do not have any supervisor_desig_wid in fact table. any help is deeply appreciated.

Yes,Duplicate the fact table create a primary key on the newly fact table alias dimension table.So you can ur data modelling as usual.

How to achieve parent-child relationship using self join?

my table structure is as follows
parent child name
-1     1     A1
1     2     A2
1     3     A3
how to achieve the hierarchy model using self join. this can be easily achieved using "connect by prior". but how to achieve the same using self join?

Hi,
Yes, that's definitely possible. If you only need to display two levels from the hierarchy, a self-join is a good option. Make it an outer join if you need to show everyone on one level, regardless of whether they have a match on the other level or not; for example, if you want the output:
child_name     child_id     parent_name     parent_id
A1          1
A2          2          A1          1
A3          3          A1          1It's good that you posted some sample data. Now post the results you want from that data, and your query (what you think is the best attempt you've made so far). If you haven't tried anything so far, then look at some other simple self-join to get ideas.

How to avoid duplicates in CROSS JOIN Query

Hi,
I am using CROSS JOIN to get all the subset of a table col values as shown below:
PRODUCT (Col Header)
Bag
Plate
Biscuit
While doing cross join we will get as
Bag Bag
Bag Plate
Bag Biscuit
Plate Bag
Plate Plate
Plate Biscuit ..... like this
By placing where condition prod1 <> prod2 to avoid Bag Bag and Plate Plate values. So the output will be like below
Bag Plate
Bag Biscuit
Plate Bag
Plate Biscuit
Now "Bag Plate" and "Plage Bag" are same combination how to avoid these records. My expected result is
Bag Biscuit
Plate Biscuit

This is the the solution that I found as fit to the OP question, but
Visakh16 already posted the same idea (assuming the names are unique) from the start and I don't think that anyone notice it!

How to perform a self-join in WebI?

Post Author: willgreenland
CA Forum: WebIntelligence Reporting
I want to perform a self-join on a table in WebI, in order to achieve the following result (of course, if there is another way of doing this I'd be glad to hear it):
I have a table that lists the department in which an employee is located at given dates in the past:
EMPLID    DEPT    DATE
123                Sales    2007...
I want to use this table to track migration between departments, in other words I want to produce the following output table, showing how in 2008, 5 employees moved from Sales to Marketing (etc):DEPT_A    DATE_A    DEPT_B    DATE_B    COUNT(EMPLID) Sales        2007          Mrkting      2008             5...
In order to do this in SQL, I would do the following:
SELECT a.DEPT, b.DEPT, count(distinct EMPLID)FROMEMPL_DEPT a, EMPL_DEPT b        // note the self-join hereWHERE( a.EMPLID = b.EMPLID AND a.DATE = '2007' AND b.DATE = '2008' )GROUP BY a.DEPT, b.DEPT;
Is there a way of doing this in WebI, ideally without resorting to manual SQL editing (I want this to be a report that other users can make sense of without necessarily getting into the SQL)?

Post Author: amr_foci
CA Forum: WebIntelligence Reporting
you cant do something like that in the WebI directly, you have to manager that at the unvinerse level first
good luck

How to avoid Duplicate Records while joining two tables

Hi,
I am trying to join three tables, basically two tables are same one is like history table, so I wrote a query like
select
e.id,
e.seqNo,
e.name,
d.resDate,
d.details
from employees e,
((select * from dept)union(select * from dept_hist)) d
join on d.id=e.id and e.seqno=d.seqno
but this returing duplicate records.
Could anyone please tell me how to avoid duplicate records of this query.

Actually it is like if the record is processed it will be moved to hist table, so both table will not have same records and I need the record from both the tables so i have done the union of both the tables, so d will have the union of both records.
But I am getting duplicate records if even I am distinct.

How to re-write this self join update using a CTE

I would like to improve my performance on this update statement and would like to try re-writing using a CTE:
UPDATE "usr_sessions" "a" SET "is_ended_at_trustable" = 't'
WHERE (
EXISTS (
SELECT 1
FROM "usr_sessions" "b"
WHERE "a"."ended_at" = "b"."started_at"
AND "a"."usr_space_id" = "b"."usr_space_id"
AND "a"."account_id" = "b"."account_id"
) ) AND "a"."is_ended_at_trustable" IS NULL
Any help is greatly appreciated! Open to other suggestions as well if there is a better way!

If I understood your description correctly, here's a way to accomplish the same thing, while dodging the need for the self join. The update itself won't be any faster, but the overall query leading to the update will likely be faster sans self-join.
(If my interpretation wasn't exactly what you meant, tweak the "partition by" clause).
MERGE is generally considered better then UPDATE, but your particular update isn't at risk for the shortcomings of update (still, Merge is newer, cooler, and more trustworthy).
Setup_Example_Data:
Declare @Usr_Sessions table (account_id int, usr_space_id int, is_ended_at_Trustable Char(1), started_at varchar(99), ended_at varchar(99))
Insert @Usr_Sessions
Select 1, 10, 't', 'A1', 'A1'
UNION ALL Select 2, 20, 'f', 'B1', 'B2'
UNION ALL Select 3, 30, NULL, 'C1', 'C1'
UNION ALL Select 4, 40, NULL, 'D1', 'D2'
UNION ALL Select 5, 50, NULL, 'E1', 'E2'
UNION ALL Select 5, 51, NULL, 'E3', 'E3'
UNION ALL Select 6, 61, NULL, 'F1', 'F2'
UNION ALL Select 6, 62, 't', 'F3', 'F3'
UNION ALL Select 6, 62, 'f', 'F4', 'F4'
Select 'Before', * from @Usr_Sessions
OP_Query:
BEGIN TRAN
UPDATE A SET is_ended_at_trustable = 't' from @usr_Sessions A-- Select * from @Usr_Sessions "a" --
WHERE (
EXISTS (
SELECT 1
FROM @usr_sessions "b"
WHERE "a"."ended_at" = "b"."started_at"
AND "a"."usr_space_id" = "b"."usr_space_id"
AND "a"."account_id" = "b"."account_id"
) ) AND "a"."is_ended_at_trustable" IS NULL
Select 'After 1', * from @Usr_Sessions
ROLLBACK TRAN /* Just to reset test data to original form, so second query below runs against original data */
Dodge_Self_Join:
With X as
Select *
, count(case when started_at = ended_at and is_ended_at_trustable is null then 'x' else null end)
over(partition by account_id, usr_space_id) as Updatable
From @Usr_Sessions
Update X
set is_ended_at_Trustable = 'T'
where Updatable > 0 -- EDIT -- fixed error, previously said "updatable = 1"
Select 'After 2', * from @Usr_Sessions

How to avoid the message in the dashboard report

Hi,
I am developing Dashboard reports(graphs) using WAD. Query and WAD are working fine. I need to put a variable for Calendar Month or Year in the graph .I am populating the Variable with default value initially and I am getting the correct result . But if I change the Variable value second time, I am getting a message (type I(information) ) in the same screen which says that 'You cannot change variable ZCALYEAR_WT01 for charact. 0CALYEAR during query navigation' . And below is the detailed information about the error message.
The Can be changed in query navigation property has been set for variable ZCALYEAR_WT01, characteristic 0CALYEAR. However, the variable is used in the query in such a way, that the system is unable to apply this change-option.
This can, for example, occur under the following conditions:
Characteristic 0CALYEAR is filtered by additional restrictions (the restrictions must be joined using an OR-connection)
A second characteristic, which is restricted by a variable, is compounded to charcteristic 0CALYEAR.
Variable ZCALYEAR_WT01 is a hierarchy node variable, but the hierarchy has not been determined uniquely.
A variable can be changed during query navigation only if it is used exclusively in a drilldown-characteristic, and there are no further restrictions to the characteristic other than this variable. There must be no additional characteristics with variables compounded to the characteristic you are working with. For variables for hierarchy nodes, the hierarchy must be determined uniquely and agree with the set display hierarchy.
Also, if the characteristic value is moved, for example (ZCALYEAR_WT01 - 1), the variable is no longer able to be changed when navigating queries.
System Response
The entry ZCALYEAR_WT01 Can be changed during query navigation is not applied.
Procedure
I checked the query definition and it is not having any offset or any other restrictions for Calendar Year
It is used for finding the total quantity by country for the year .Hence Quantity keyfigure is added in the Keyfigures and Country is in the Rows and Calendar Year is restricted with Variable in the global filter .There are no other fields and no other restrictions .
I am still trying to figure out why the warning apprears in the DashBoard. Since this Dashboard report will be used by the Power users and this warning message will be annoying to them .Hence I need to find how to avoid this message.
Kindly do let me if anyone has faced this and solved earlier.
Thanks for your time.
Thanks & Regards,
Raja

Hi Nick,
Thanks for your suggestion and it worked for me I added the 'System message' web item and set the visibility to 'Hidden' .Now I am not getting any message. Thank you for both.
Thanks & Regards,
Raja

follow steps
1)     Execute query so we can get data set
2)     Clear matrix and data source (omatrix.clear(), oDBS.Clear())
3)     Open loop
4)     Insert record to oDBS using oDBS.InsertRecords(oDBS.Offset)
5)     Then set value using oDBS.Setvalue(u2026u2026
6)     Move next record
7)     Finally close the loop
8)     Matrix load from record set using oMatrix.LoadfromData()
it will be work
