Thank you,

As well as EXPLAIN PLAN, let us know what proportion of rows are visited by this query. It may be that it is not using a full table scan when it should (or vice versa).
And of course we'd need to know what indexes are available, and how selective they are for the predicated you have in this query ...

How to select this field for the extractor?

Hi Gurus, I hope you are fine!
I need to extract the field     PRED_OPPT_GUID   form the Data source 0CRM_SRV_CONTRACT_H inside CRM system.
If I go inside CRM to:
Transaction SBIW -> Settings for BW Adapter -> Maintain DataSource and Enhance BW Adapter Metadata ->
tipe "0CRM_SRV_CONTRACT_H" and press change buttom -> Mapping TAB
there I can see the field I need "PRED_OPPT_GUID" but this is not selected at the "BW Selection" Column , I guess this is the cause why I am not receiving this field from the extractor, Am I right?
If yes, How can I select this field for the "BW Selection" Column? (the system does not allow me to click it directly)
if not, what is the proper procedure if I need to extract this field ? because this is the key field for the DSO
" Service Orders: Header Data "
Thanks

This is what i can see inside the ROOSFIELD table:
Filtered by data source = 0CRM_SRV_PROCESS_H
Comparison with another field:
BILL_TO_PARTY (working properly)    columns:        SELECTION = X              NOTEXREL= Y
PRED_OPPT_GUID (Not working)           columns:        SELECTION = (Empty)    NOTEXREL= Y
I think that if I try to change the Selection field to X it will cause inconsistencies with the SMOXRELP table am I right ?
I tried to change using the system and not directly into the tables, but thaere was an inconsitecie between these 2 tables.
Why is no able this field taking into account that this is the KEY FIELD inside the standard DSO? it has no sense to me.
What do you think?
regards.

How to write selection Query for the following requirment.

Hi All,

Hi,
Its easy for you if you learn SELECT with JOIN to complete your task. So SEARCH the forum with SELECT statement and you will get a lot of examples using which you can write your own.
If you struck up anywhere revert back.

In general case, you cannot write this query.
This is one of the limits of relational database concepts. The number of columns must be known up-front. In the SELECT clause, you have to list and name all columns returned by the query. So you have to know number of departments. (There are some workarounds - you can return one column with concatenated values for all departments, separated by space character).
If you know that you have 3 departments then you qurey will return 4 columns:
SELECT
   e.job,
   SUM ( CASE WHEN d.deptid = 10 THEN e.sal ELSE NULL END) d10,
   SUM ( CASE WHEN d.deptid = 20 THEN e.sal ELSE NULL END) d20,
   SUM ( CASE WHEN d.deptid = 30 THEN e.sal ELSE NULL END) d30
FROM dept d, emp e
WHERE d.deptno = e.deptno
GROUP BY e.job

How to find out query for the deleted record.

Hi Guys,
We are using Oracle9i release 1. We are about 5 employees who are working on the same application. All Employee are connected to the same Schema (User)
User: Employee/web
Now one of the user have deleted like 200,000 records from a table. We just want to trace out the query by which these records were deleted.
From which file i can get the log of executed queries so that i can recover the data.
Just want to know the query executed for this deletion of records?
we are using windows server.
Regards,
Imran Baig

If you do not need an exact query, but only the way you can reconstruct the data, LogMiner can be solution for you. Below I have put a simple example you can review it if you want.

Some Basic steps How to tune this Query

Hi
as I tried to say is that DECODE is just hard to read, but not a performance issue.
What do you do in the XXHDNL_OM_QUI_BAT_PLAN_EXT_PKG.check_push_or_pull(oeol.line_id) procedure?
But let me try the DECODE... not 100% correct as I can't test but you'll get the picture:
SELECT
FROM
WHERE oeol.flow_status_code IN
CASE WHEN oett.name = xxhdnl_om_common_util_pkg.g_push_line_type THEN
   CASE WHEN oeol.shipment_priority_code = 'EXPRESS' THEN
      CASE WHEN oeol.flow_status_code ='AWAITING_STOCK' THEN 'AWAITING_STOCK'
           WHEN oeol.flow_status_code ='STOCK_RECEIVED' THEN 'STOCK_RECEIVED'
           ELSE null END
      ELSE
      CASE WHEN XXHDNL_OM_QUI_BAT_PLAN_EXT_PKG.check_push_or_pull(oeol.line_id) = 'PUSH' THEN 'BOOKED'
         ELSE NULL END
ELSE
NULL
ENDThat is a 1:1 "translation" PLEASE add comments in nested statements.
And this is easier to read, as in CASE you can use AND / OR / IN ....
SELECT
FROM
WHERE oeol.flow_status_code IN
CASE WHEN oett.name = xxhdnl_om_common_util_pkg.g_push_line_type THEN
   CASE WHEN oeol.shipment_priority_code = 'EXPRESS' AND oeol.flow_status_code IN ('AWAITING_STOCK','STOCK_RECEIVED')
     THEN oeol.flow_status_code ELSE NULL END
   ELSE
    CASE WHEN XXHDNL_OM_QUI_BAT_PLAN_EXT_PKG.check_push_or_pull(oeol.line_id) = 'PUSH' THEN 'BOOKED'
         ELSE NULL END
ENDThe "oeol.flow_status_code IN" makes no sense as the output of/DECODE/CASE is always 1 value right? And I would use the logic on a select on table "oe_order_lines_all" and then use the calculated field as a JOIN criteria. Much easier to test and read.
But, please check the procedure which you call that can be deadly! The "case" is just "nice to have"

Hi.how to tune this query?

select *
from exp_final
where
to_number(to_char(process_date,'mm'))=to_number(to_char(sysdate,'mm'))-1

Both Sven's and theoa's suggestions are fundamentally different from the query OP referred to originally.
It maybe that the original query is completely wrong (that would be my instinct too).
Original query:
select *
from exp_final
where
to_number(to_char(process_date,'mm'))=to_number(to_char(sysdate,'mm'))-1 implies that you want everything from exp_final where the process_date was in the same month as the current month -1, regardless of year. For example, run today this will bring back everything done in a December, whether it was December 1972, December 1815 or December 2010.
Whereas their suggestions rely on your query being wrong and what you really want to get is everything from last month - i.e. run today, fetch everything from December 2010.
Which is the correct requirement?

any help my dearsIf you can draw one simple tree example. Then it will be easy to create query. Because i am confuse about the output. Just draw one example of your desired output tree. Then it will help to find solution.
And while writing query or any example so use the 6 digit before and after your query or example to keep the formatting in orignal format. Otherwise it becomes hard to read.

How to modify this query to get the desired output format

I hv written a Query to display all the parent table names and their primary key columns(relevant to this foreign key of the child table).The query is given below...
SELECT DISTINCT(TABLE_NAME) AS PARENT_TABLE,COLUMN_NAME AS PARENT_COLUMN
FROM ALL_CONS_COLUMNS
WHERE CONSTRAINT_NAME IN (SELECT AC.R_CONSTRAINT_NAME
FROM ALL_CONSTRAINTS AC
WHERE AC.TABLE_NAME=TABLE_NAME
AND AC.TABLE_NAME='&TABLE'
AND AC.R_CONSTRAINT_NAME IS NOT NULL);
This query will display all the parent tables and their primary key columns.Now my problem is that how to modify this query to also display the foreign key column name of the child table.
I want the query result in the following format.The query should display the following columns.1)child table's name,2)child table's foreign key column name,3)the corresponding parent table's name,4)the parent table's primary key column name(which is the foreign key in the child table).
For Example I want the output as follows...
TAKE THE CASE OF SCOTT.EMP(AS INPUT TO YOUR QUERY)
CHILD_TABLE CHILD_COLUMN PARENT_TABLE PARENT_COLUMN
EMP DEPTNO DEPT DEPTNO
In this result I hv used alias name for the columns.The query should display this only for the foreign keys in the child table.In the query which I sent to you earlier will give the parent table and the parent column names,But I also want to append the child table and child column names there.
any help on how to tackle would be appreciated.

Try this query
SELECT c.table_name child_table,
     c.column_name child_column,
     p.table_name parent_table,
     p.column_name parent_column
FROM user_constraints a,user_constraints b,user_cons_columns c,
     user_cons_columns p
WHERE a.r_constraint_name=b.constraint_name and
      a.constraint_name=c.constraint_name and
      b.constraint_name=p.constraint_name and
      c.position=p.position
ORDER BY c.constraint_name,c.position

When I run the same query for the second time it's faster, I want to reset this behavior

I am running a query in oracle 11g select A from B where C = ':D' B has millions of records.
The first time i run it it takes about 30 seconds, the second time i run the query it takes about 1 second.
Obviously it's caching something and i want it to stop that, each time i run the query i want it to take 30s - just like it was running for the first time.
The reason I want to reset this is because for testing purposes I want to measure this query at the very first time.
Please help.
Thanks & Best Regards,
Dark

No - you do NOT want to do that. Not if you want to get results that really represent how that query will work in reality.
See these two AskTom blogs where he discusses the reasons for NOT doing this in detail.
