• Problem with deployment on Simulator ("program file does not exist")

  Hello

  I currently have a problem with a project, I can't deploy it more in the Simulator: I always get an error "the file does not exist.

  The project itself can be compiled without any isse. I can also deploy the application on my phone without problem. But when I'm trying to deploy on the virtual machine, it says:

  Program file does not exist
  /Users/..../HFR10/arm/o.le-v7-g/HFR10 not found
  /Users/..../HFR10/arm/o.le-v7-g/HFR10 not found
  /Users/..../HFR10/arm/o.le-v7-g/HFR10 not found
  

  # the application is called, HFR10...

  What is strange, is that it looks at the folder "arm", which does not exist when I compile for the virtual machine since the architecture should be "x 86"... ".

  In the x 86 folder, I can find the compiled application...

  I tried to update the descriptor of bar:

      
         armle-v7
         HFR10
      
      
         Qnx/Cascades
         armle-v7
         HFR10.so
      
      
         armle-v7
         HFR10
      
      
         x86
         HFR10
      
  

  And modified the Simulator-Debug field that used to point to the folder 'arm '...

  but after a cleaning + reconstruction, I line have the same error, and he always looks inside the arm folder...

  No idea of what the problem is? This problem appeared when I moved from momentic 2.0 to the 2.1 beta...

  But I guess that he changed something in the configuration file, because even if I go back to momentic 2.0, I still have it exactly the same problem...

  Thank you!

  UM... In the dialog box "edit configuration", I spend 'use the workspace settings' to "Enable auto build" and it works to restarted...

  

  It's strange, the application was already built and available in the x 86 folder...

  In any case... Perhaps it would be useful for someone else...

• insert this line does not exist

  Hi all
  
  I need to insert a line using the daily procedure. Insert must only be performed when this line does not exist in the table. Please suggest me a decision. I know it's simple question, sorry for disturbing (Burns my brain).

  Hello

  Use MERGE.
  http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_9016.htm#sthref9082
  If you use Oracle 10 (or higher) then you don't need a section "WHEN MATCHED.

  If you want to know, post a small example of data (CREATE TABLE and INSERT statements, showing all the tables involved, as they exist prior to the INSERTs in question). Put one or two unconditional instructions INSERT (including an example of each matching rows found and not found) and the results you want (that is, the content of the table changed after the INSERTs).
  Always tell what version of Oracle you are using.

• You want to capture update dates, with trigger on a view to refresh quickly materialized. But trigger on MV consider inserting and updates are inserts only.

  Oracle Database 11 g Enterprise Edition Release 11.2.0.4.0 - 64 bit Production

  CORE Production 11.2.0.4.0

  AMT for Linux: Version 11.2.0.4.0 - Production

  NLSRTL Version 11.2.0.4.0 - Production

  I create the structure of the table like that.

  create table test1 (a primary key, b (2) char number, date c, d varchar2 (10), date of e);

  create table test2 (number of ab, cd (2) tank, date of the ef, gh varchar2 (10), date of the ij, kl varchar2 (100));

  Create materialized view log on test1;

  create materialized view fast refresh test1_v on commit in select * from test1;

  I have create a trigger of the sample

  CREATE OR REPLACE TRIGGER test1_trig

  AFTER INSERT OR UPDATE OR DELETE

  ON test1_v

  FOR EACH LINE

  DECLARE

  lr_test2 test2% ROWTYPE;

  lv_error VARCHAR2 (4000);

  BEGIN

  lr_test2. AB: =: NEW.a;

  lr_test2. CD: =: NEW.b;

  lr_test2. GH: =: NEW.d;

  IF THE INSERTION

  THEN

  lr_test2.IJ: = SYSDATE;

  lr_test2.KL: = 'INSERT ';

  INSERT INTO test2

  VALUES lr_test2;

  THEN

  lr_test2.IJ: = SYSDATE;

  lr_test2.KL: = 'UPDATE ';

  UPDATE test2 = lr_test2 ab WHERE = LINE: OLD.a;

  ELSIF REMOVAL

  THEN

  DELETE FROM test2

  AB = WHERE: old.a;

  END IF;

  VALUES ('test1_trig',

  : OLD.a,.

  "test1_trig,"

  LV_ERROR,

  SYSDATE);

  COMMIT;

  END test1_trig;

  /

  So, if check you my code,.

  When I insert EF = SYSDATE, IJ = SYSDATE.

  Update EF is not changed, IJ = SYSDATE.

  So I like to capture their insertion and update dates.

  But if updates or insert arrives on the materialized table. The trigger themselves as an INSERT only.

  So how do you capture the updates?

  I use the statemnet with out merger with performance and also able to capture the update dates.

  CREATE OR REPLACE TRIGGER test1_trig_merge

  AFTER INSERT OR UPDATE OR DELETE

  ON test1_v

  FOR EACH LINE

  DECLARE

  lr_test2 test2% ROWTYPE;

  lv_error VARCHAR2 (4000);

  BEGIN

  IF THE REMOVAL

  THEN

  DELETE FROM test2

      AB = WHERE: old.a;

  ELSIF INSERTION

  THEN

  MERGE INTO test2 one

  B using (SELECT 1 FROM DUAL)

  WE (ab =: new.a)

  WHEN MATCHED

  THEN

  UPDATE the VALUE ab =: NEW.a.

  CD =: NEW.b,

  GH =: NEW.c

  IJ = SYSDATE,

  KL = "Update"

  AB WHERE =: old.a

  WHEN NOT MATCHED

  THEN

  INSERTING VALUES (: NEW.a,)

• Help with this sql. Only select employees in a separate Org?

  Hi guys, simple query.
  

  create table balancetest(emp_id number, balance_id number, balance number, org number);
  
  insert into balancetest values (111, 1, 1, 0);
  insert into balancetest values (111, 1, 1, 0);
  insert into balancetest values (111, 2, 1, 1);
  insert into balancetest values (222, 1, 2, 1);
  insert into balancetest values (333, 3, 4, 3);
  insert into balancetest values (333, 3, 4, 2);
  
  commit;
  
  SQL> select * from balancetest;
  
      EMP_ID BALANCE_ID    BALANCE        ORG
  ---------- ---------- ---------- ----------
         111          1          1          0
         111          1          1          0
         111          2          1          1
         222          1          2          1
         333          3          4          3
         333          3          4          2
  
  6 rows selected.

  As you can see, emp_id 111 appears on different Org (0 and 1). I need to calculate the balance, but the requirement says that I need to get employees appearing only in 1 body. It won't matter what org is selected (business rules provide balance will be the same), as long as if an employee is in the multiple org, this employee is selected only once for an org. So my result will be something like:
  

      EMP_ID BALANCE_ID    BALANCE        ORG
  ---------- ---------- ---------- ----------
         111          1          1          0
         111          1          1          0
         222          1          2          1
         333          3          4          3
         333          3          4          2

  or,

      EMP_ID BALANCE_ID    BALANCE        ORG
  ---------- ---------- ---------- ----------
         111          2          1          1
         222          1          2          1
         333          3          4          3
         333          3          4          2

  In other words, an employee should appear only in 1 org my result.
  
  any ideas? I tried:
  

  select * from balancetest bal1
  where not exists ( select bal2.emp_id from
                             balancetest bal2
                             where bal2.emp_id = bal1.emp_id
                             and bal2.org <> bal1.org
                             );

  But I guess that's not as simple as that!

  Hello

  You can find the smallest number org for each employee like this:

  SELECT    emp_id
  ,         MIN (org)  AS min_org
  FROM      balancetest
  GROUP BY  emp_id;
  

  You can get the desired results by selecting only the lines in balancetest that corresponds to a line in that the result above. There are several ways to do so, as a join:

  WITH  g  AS
  (
      SELECT    emp_id
      ,         MIN (org)  AS min_org
      FROM      balancetest
      GROUP BY  emp_id
  )
  SELECT  b.*
  FROM    balancetest  b
  JOIN                 g  ON  b.emp_id = g.emp_id
                          AND b.org    = g.min_org;

• Select with Where not in (subselect)

  Hello
  Are there any special about 'no' in the ORacle sql (10g) that it returns me all the lines, unlike SQL Server with the same code:
  

  select count(*) from t1_ups where  id_ups not in (select b.id_ups from t1_dups b)
  COUNT(*)               
  ---------------------- 
  0 
  
  vs.
  select count(*) from t1_ups where  id_ups not in ('abc', 'def','xyz')  --select b.id_ups from t1_dups b)
  COUNT(*)               
  ---------------------- 
  16 
  
  DDL:
      "id_ups"            VARCHAR2(20 BYTE),   is the same for both tables.

  I see that to remove < not > it works fine. is there any GOLD-> happaned plate AND with the negation?
  My overall task is to make the UNION "with replacement" when if any records exist in id_dups they will replace those of id_ups, so I try to make it into several parts.
  
  Thank you

  Use NOT EXISTS instead of NOT IN.

  select count(*) from t1_ups u where
  not exists (select b.id_ups from t1_dups b where b.id_ups= u.id_ups)
  

• To only convert NOT EXISTS query JOIN plain

  Version: 10.2.0.5
  
  Developers have complained that the following query works very poorly and hooked most of the time.
  
  

  select distinct cust_id from cust_track_dtl TD
       where not exists 
       (select 1 from cust_master CM where TD.cust_id = CM.cust_id 
       and CM.rgn_code = TD.rgn_code
       CM.rgn_code = 'AP'
        )
  and TD.stat_code = 'C'
  and TD.proc_flag = 'Y'
  TD.rgn_code = 'AP'  ; ----------------> Is this logically correct ?

  CUST_TRACK_DTL table in the outer query has 2 million records
  
  CUST_MASTER table in their inner query(sub query) has 30 million records

  Currently, we are only at the design phase. I'm a bit confused about the
  

  rgn_code = 'AP'

  appearing in internal and external queries.
  
  I think that the motion seeks to recover all customers who are not the "AP" region, but the outer query WHERE clause has

  TD.rgn_code = 'AP'

  Is there something wrong with this logic?
  
  If it is logically correct, how can I convert this request with simple JOIN (ie. How can I get rid of NO thing EXISTS)?

  Your original. Rgn_code = "AP" is not necessary in the subquery but will change the results of the outer query.

  select distinct cust_id from cust_track_dtl TD
    left outer join cust_master CM
      on (TD.cust_id = CM.cust_iid AND
          CM.rgn_code = TD.rgn_code)

• That IS NULL is done by replacing the NOT EXISTS operator with an outer join?

  DB version: 10 gr 2
  
  An example of searchoracle.target.com
  
  The query that contains a NOT EXISTS operator

  SELECT M.ModulId, M.Modul FROM MODULE M
  WHERE NOT EXISTS
  ( SELECT PROJEKTMODUL.IdModul 
    FROM PROJEKTMODUL 
    WHERE M.ModulId = PROJEKTMODUL.IdModul 
    AND PROJEKTMODUL.IdProjekt = 23 )

  is replaced by an equivalent outer join query
  

  select distinct

       , M.Modul 
    from MODULE M
  left outer
    join PROJEKTMODUL
      on M.ModulId = PROJEKTMODUL.IdModul

   where PROJEKTMODUL.IdProjekt is null

  I do not understand what

  PROJEKTMODUL.IdProjekt is null

  fact in the above rewritten query.

  He is to perform an anti-jointure. As far as I know Oracle (starting with version 10g - I thought that release 1) rewritten a Join Anti that resembles your second query of your request NOT EXISTS and NOT IN.

  Look at the results of the query without the predicate IS NULL and see what records (from this set) must be selected to show the same results as the first query. Areas of interest match the predicate IS NULL.

• Email not sent by INSERT trigger with utl_mail

  Hello
  I have a trigger that is sending an e-mail whenever a particular column (ATTRIBUTE11) is inserted with the value or updated.
  E-mail should be sent when the table (ATTRIBUTES) is inserted with a value of ATTRIBUTE11 (IE, ATTRIBUTE11 is not null)
  An email must not be sent on the update of the same value in this column (former. ATTRIBUTE11 = new. ATTRIBUTE11) and also an email must not be sent if the table is inserted without value in ATTRIBUTE11
  
  ATTRIBUTES of table has a structure:
  Account varchar2 (20);
  Attribute11 varchar2 (20);
  user_name varchar2 (20);
  
  Triggering factor:
  CREATE OR REPLACE TRIGGER "TPP_SND_EMAIL".
  AFTER INSERTION OR UPDATE OF ATTRIBUTE11
  ON GENEVA_ADMIN ATTRIBUTES.
  REFERRING AGAIN AS NINE OLD AND OLD
  FOR EACH LINE
  WHEN)
  OLD. ATTRIBUTE11 <>NEW. ATTRIBUTE11
  )
  DECLARE
  MSGBODY varchar2 (50);
  BEGIN
  () UTL_MAIL. Send
  sender = > "hemanth11"yahoo.co.in"
  recipients = > "[email protected]"
  subject = > "Test mail through utl_mail.send."
  message = > msgbody,.
  mime_type = > ' text/plain '.
  );
  EXCEPTION
  WHILE OTHERS THEN
  dbms_output.put_line (' error: ' |) SQLERRM);
  END TPP_SND_EMAIL;
  /
  
  * One Email is not sent whenever a new row is inserted in this table whose value ATTRIBUTE11 (this happens). *
  The trigger is activated an email successfully each time an update happens on the column.
  
  Do we not have an option to manage the when clause differently for INSERT and UPDATE differently or is theer a way to manage the same in the trigger above.
  
  Please help me in this regard.

  It is always wrong.

  What happens if this code UTL_MAIL ends up with slow network response or an SMTP server overloaded? What happens if the SMTP server is down and the mail cannot be sent? What happens to the transaction then?

  Your code is involved not only with the execution of the transaction, but also the integrity of the transaction. It is absolutely not a single justification for this approach to coding a ULT_MAIL delivery within a trigger. Is bad.

  The right approach creates a notification or an event to create and deliver an e-mail message. Where the process that will make this event or act on this notification
  (a) may have retry mechanisms for mail failures
  (b) has no impact in any way shape or form on the transaction that created the event or notification

  Violate this fundamental principle to your own (and the base of data and transaction) risk.
