Select records based on criteria and update those records once read

hi,
I am very new to bpel and DB adapters.
I have a requirement where in I need to query two tables to fetch some records and update these selected records with a new value for field to indicate that bpel has processed these records.
Once I select these I needs the output to be mapped to the output variable.
I am able to select the records based on criteria , but how will i lock these records so that these records do not get processed again. This should be a very simple usecase just that I am not aware.
Thanks,
Robin

Once you have finished reading the records fire an update query , update some field in the table so that it does not get picked up next time.
if you are using polling for picking up the records, then use logical delete scenario, refer....http://docs.oracle.com/cd/E15523_01/integration.1111/e10231/adptr_db.htm#BABEEBIH

Select list based on LOV - and allowing new values

Hi All,
I have a page that has a select list based on a dynamic list of values. I wanted to test out how the system was working, so I truncated all of my tables, and now my select list is blank (which makes sense). The problem is that I can't type anything into the select list. How can I make it so that if there isn't a value returned from the query that populates the LOV, I can just type one in? This also goes further in that if the value I wanted isn't already in the db, how does the user add in another value?
Thanks in advance,
Corey

Hello,
Well as you now know HTML based select lists don't work like that, that widget is called a combo box and there will be built in combo boxes in APEX 3.0, it's a fairly complex dhtml widget.
What you might want to do is provide a text item next to your select box and an Add New Value Option in your select list.

Right clicking PDF files and printing those with Acrobat Reader X

We have a Windows XP computer with Adobe Acrobat 7 Professional and Acorbat Reader X.
Now when we open PDF files they open with Acrobat Reader X wich is fine.
But when we try selecting PDF files and right click Print them they print with Acrobat 7 Professional.
The problem is with Adobe Acrobat Professional 7 it doesn't print all the files we selected.
We select 50 files and only about 10 are printed and those are always random.
So is there anyway to enable the print option to print with Acrobat Reader X ?

This is not a desirable situation. Adobe recommends against having Reader and Acrobat on the same machine, unless they're both version X, exactly because it can cause this kind of conflicts.

Selecting Records from 125 million record table to insert into smaller table

Oracle 11g
I have a large table of 125 million records - t3_universe. This table never gets updated or altered once loaded, but holds data that we receive from a lead company.
I need to select records from this large table that fit certain demographic criteria and insert those into a smaller table - T3_Leads - that will be updated with regard to when the lead is mailed and for other relevant information.
My question is what is the best (fastest) approach to select records from this 125 million record table to insert into the smaller table. I have tried a variety of things - views, materialized views, direct insert into smaller table...I think I am probably missing other approaches.
My current attempt has been to create a View using the query that selects the records as shown below. Then use a second query that inserts into T3_Leads from this View V_Market. This is very slow. Can I just use an Insert Into T3_Leads with this query - it did not seem to work with the WITH clause?    My Index on the large table is t3_universe_composite and includes zip_code, address_key, household_key.
CREATE VIEW V_Market as
WITH got_pairs    AS
     SELECT /*+ INDEX_FFS(t3_universe t3_universe_composite) */ l.zip_code, l.zip_plus_4, l.p1_givenname, l.surname, l.address, l.city, l.state, l.household_key, l.hh_type as l_hh_type, l.address_key, l.narrowband_income, l.p1_ms, l.p1_gender, l.p1_exact_age, l.p1_personkey, e.hh_type as filler_data, 1.p1_seq_no, l.p2_seq_no
     ,      ROW_NUMBER () OVER ( PARTITION BY l.address_key
                                  ORDER BY      l.hh_verification_date DESC
                  ) AS r_num
     FROM   t3_universe e
     JOIN   t3_universe l ON
            l.address_key = e.address_key
            AND l.zip_code = e.zip_code
          AND   l.p1_gender != e.p1_gender
             AND   l.household_key != e.household_key
             AND l.hh_verification_date >= e.hh_verification_date
SELECT *
FROM got_pairs
where l_hh_type !=1 and l_hh_type !=2 and filler_data != 1 and filler_data != 2 and zip_code in (select * from M_mansfield_02048) and p1_exact_age BETWEEN 25 and 70 and narrowband_income >= '8' and r_num = 1
Then
INSERT INTO T3_leads(zip, zip4, firstname, lastname, address, city, state, household_key, hh_type, address_key, income, relationship_status, gender, age, person_key, filler_data, p1_seq_no, p2_seq_no)
select zip_code, zip_plus_4, p1_givenname, surname, address, city, state, household_key, l_hh_type, address_key, narrowband_income, p1_ms, p1_gender, p1_exact_age, p1_personkey, filler_data, p1_seq_no, p2_seq_no
from V_Market;

I had no trouble creating the view exactly as you posted it. However, be careful here:
and zip_code in (select * from M_mansfield_02048)
You should name the column explicitly rather than select *. (do you really have separate tables for different zip codes?)
About the performance, it's hard to tell because you haven't posted anything we can use, like explain plans or traces but simply encapsulating your query into a view is not likely to make it any faster.
Depending on the size of the subset of rows you're selecting, the /*+ INDEX hint may be doing your more harm than good.

Select Materials based on Characteristics

Hello,
I would like to select specific materials (MARA) based on the assigned characteristics and values (AUSP).
My first approach would be the following: select table AUSP with the characteristic and value, then select MARA with MARA-CUOBF = AUSP-OBJEK.
But, the problem is, that there is no index on the field MARA-CUOBF.
Is there another way to select material based on characteristics and values? Does there any index table or reference table exist?
Thank you for your assistance in advance.
Best Regards,
Kurt.

Hi Kurt,
there is a way if u know the characteristic of the material.
give characteristic in AUSP-ATINN field in AUSP table.
collect all OBJEK's for that characteristics.
then go to table INOB, select objek from inob into itab where cuobj = ausp-objek.
INOB-OBJEK gives u a combination of material number and batch number for that material number. ( there might be different batches for one material).
so collect inob-objek and split into matnr and batch.
there u get all materials according to ur characteristic
and also collect those objeks where ur matnr is there.
and regarding to that matnr and batch in MSEG table u can do rest of the stuff....
reward if it helps

I have an 8500a how, once I select the apps I want and add to the printer. How do i get them to work? And is it always this slow....

Hey jmknights!
While I can't speak to how quickly the apps will work, I may be able to help you with how they work. Once you have the apps added to the printer you would select the app you want to print from on the printer's front panel. Once inside the app, select what you want to print and if all goes as it should, the printer should begin printing the requested information within a few seconds.
Hope this helps!

When i try to update my iPhone 3gs with new IOS and it won't restore and update

i Tried to update my 3Gs with the new IOS 5 and now it has the plug into itunes sign. I plugged it into itunes and it told me its in recovery mode and it needs to be restored. when i click restore i can only restore and update it but once it is don extracting the software and preps it for restore it tells me it has an unknow error. when i hit ok it tells me to restore it again. i tried all the troubleshooting steps none helped. Any ideas?

I have spent the better part of three days on this. Yesterday I took it to the Apple store and they looked at it and tried to DFU (hold the lock button for 5 seconds, then press the home button along with the lock button for 10 seconds, THEN, let off the lock button continuing til the 'connect to itunes' symbol.
They say that my phone has a bad memory module or logic board. Funny, it worked fine up until I updated. Seems to big of a coincidence to not be related.
The only thing that seemed to get access was using redsnow unlocking tool (my phone is NOT unlocked). I was desparate to try anything. I tried to load a different firmware but still no luck.
I have a blackberry through work that is paid for, so I guess its time to get rid of my iphone plan.

The bottom row of apps is unresponsive. The slide to unlock the phone works fine. I have tried restoring and updating, but it has not work. Does anyone have any suggestions?

The bottom row of apps is unresponsive to touch. The slide lock in the same location works. Does anyone know how to fix this problem? I have tried restoring and updating. Thanks!

JDBC Sender - Different number of records selected and updated.

Hi people,
We have a JDBC -> Abap proxy scenario. The JDBC sender is pooling an Oracle database to retrieve data from a table X, each 30 minutes. The select and update statements in jdbc sender are below
SELECT FIELD1, FIELD2, FIELD3 FROM MY_TABLE WHERE STATUS = 1
UPDATE MY_TABLE SET STATUS = 2 WHERE STATUS = 1
Sometimes the message sent to Abap proxy has, for example, 400 records. Looking at runtime workbench, message monitoring, for the same message there is a log like this
Channel SENDER_JDBC_CHANNEL: Query executed successfully. Start update
Channel SENDER_JDBC_CHANNEL: 510 row(s) updated successfully
Someone has already experienced something like this? How can I handle this to guarantee to update only those read records?
regards.

Hi All,
Even we are facing the same problem.
In our scenario, receiver is SAPR3. (IDOC)
Will this parameter serialization work in our case?
1. SELECT XBLNR, WERKS, MATNR, MDV01, BACKFLQUANT, STATUS, SAPTIMESTAMP, PITSTIMESTAMP, PMTIMESTAMP, BATCH FROM PMBPITS.PITS_UNITY WHERE STATUS = '01' and rownum<200 .
2. UPDATE PMBPITS.PITS_UNITY SET STATUS = '02' , SAPTIMESTAMP = sysdate WHERE STATUS = '01' and rownum<200 ( currently the value is rownum < 5 )
Thanks!!

How to select and duplicate the records and update some column values using cursor

Hi ManuGT
If I understand what you need then you ask for:
1. updating all current rows (920 rows in the table now)
2. insert new rows which are duplicates of the preiviews rows, but with value 'CCC' insteade of 'BBB'
If so, there is not reason to use a cursor and it is highly NOT RECOMMENDED to use ant type of loop.
You should work with SET and do it all in 2 simple queries:
-- first we duplicate the existing rows,
-- but we use the values 'CCC" and '20140107' for the new rows values
INSERT test (SourceName, InternalValue, ExternalValue, StartDate, EndDate)
select SourceName, 'CCC', ExternalValue, '20140107' , EndDate
from test
where
-- You can use any filter that you need if you dont want to update all rows
InternalValue = 'AAA' and ExternalValue = 'BBB' and StartDate = '20140101' and EndDate = '20140630'
-- Now we update the old rows (check the filter! I get only the old rows since I filter the new rown out)
UPDATE test
SET EndDate = '20140107' -- I use date in format yyyymmdd, You can use other formats as well
where
-- You can use any filter that you need if you dont want to update all rows
InternalValue = 'AAA' and ExternalValue = 'BBB' and StartDate = '20140101' and EndDate = '20140630'
Unfortunately you did not post DDL+DML! Therefore we cant see your table structure and the data sample and we can only guess. I used Saeid's post as the basic DDL+DML.
Please next time post DDL+DML
here is the full code with the DDL+DML that i used:
-- This is our DDL - A create table query:
create table test
( id int identity(1,1) primary key,
SourceName nvarchar(3),
InternalValue nvarchar(3),
ExternalValue nvarchar(3),
StartDate date,
EndDate date
go
-- This is our DML - A query that insert some sample data
declare @i int = 1 ;
while @i < 921
begin
insert test (SourceName, InternalValue, ExternalValue, StartDate, EndDate)
values ('XXX', 'AAA', 'BBB', '1/1/2014', '6/30/2014' ) ;
set @i += 1 ;
end ;
GO
-- Here is the solution for the problem as I understood your needs:
-- first we duplicate the existing rows,
-- but we use the values 'CCC" and '20140107' for the new rows values
INSERT test (SourceName, InternalValue, ExternalValue, StartDate, EndDate)
select SourceName, 'CCC', ExternalValue, '20140107' , EndDate
from test
where
-- You can use any filter that you need if you dont want to update all rows
InternalValue = 'AAA' and ExternalValue = 'BBB' and StartDate = '20140101' and EndDate = '20140630'
-- Now we update the old rows (check the filter! I get only the old rows since I filter the new rown out)
UPDATE test
SET EndDate = '20140107' -- I use date in format yyyymmdd, You can use other formats as well
where
-- You can use any filter that you need if you dont want to update all rows
InternalValue = 'AAA' and ExternalValue = 'BBB' and StartDate = '20140101' and EndDate = '20140630'
-- Here we just check how the result look like :-)
select *
from test ;
-- And since we do not realy need this table in our server... Here we clean the DDL (you probaby DO NOT WANT TO EXECUTE THIS!)
DROP table test
GO
I hope this was useful :-)

How to select records based on Max/Min on different columns and group by

I have a table with 5 columns(a,b,c,d,e), i need to select records based on MAX(c),Max(D) and Min(e) group by a,b. i am trying using : select max(c),max(d),min(e) from table group by a,b. this is not working. its giving me 1 6 1
a b c d e

when i group by a,b i am expecting the record 1 6 3

when i group by a,b i am expecting the record 1 6 3It looks to me like "1 6 1" is the correct answer. You're asking for the lowest value of e, and 1 is lower than 3.
Maybe you don't want MIN (e). Explain why you want 3 (that is, how you decided that 3 is the correct value for the last column) and someone will help you code it.

Whenever you have a problem, you should psot CREATE TABLE and INSERT statements for your sample data. That way, the people who want to help you can re-create the problem and test their ideas. It often helps to clarify the problem, too. since this is your first message, I'll do it for you:
CREATE TABLE     table_x
(       a     NUMBER
,     b     NUMBER
,     c     NUMBER
,     d     NUMBER
,     e     NUMBER
INSERT INTO table_x (a, b, c, d, e) VALUES (1, 1, 1, 2, 1);
INSERT INTO table_x (a, b, c, d, e) VALUES (1, 1, 1, 6, 4);
INSERT INTO table_x (a, b, c, d, e) VALUES (1, 1, 1, 6, 3);
COMMIT;
